Super 42 Braided Wire Buffer Spring and Buffer Combo

Super 42 Braided Wire Buffer Spring and Buffer Combo

Super 42 Braided Wire Buffer Spring and Buffer Combo

$65.00

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.

NOTE:  The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions. We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.

Super 42 Braided Wire Buffer Spring and Buffer Combo

Full Description

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.


Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock. The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.


NOTE:  The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions.
We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.


Additional Information

Notes The Super 42 spring and Geissele buffer are designed to work together as a set; the spring will not fit over a standard buffer. If installed with a standard buffer damage to the rifle or receiver extension will occur.

DD MK18 - COLE

Add this to my DD MK18. The gun runs both suppressed and unsuppressed without changing the buffer. Feels much smoother. WOuld recommend for anyone with a SBR that's just a tad over gassed as the DD MK18 is.

BEAUTIFUL - Aaron

This thing is smooth as butter. No rattling, no unnecessary vibration when firing, no bolt bounce. Haven't had anyone mention this but one thing I like about it is that when you lubricate it with oil really well before you shoot, I have found that with it cycling it throws a little bit of oil toward the bolt. I like that because it helps keep it from drying up after several rounds and helps keep it easier to clean. I'll never use another buffer system.

Barrel 7.5 Ar Pistol - Rene

I bougth this kit for my Ar pistol. It's seems amazing . I have a geissele Trigger SSA -E and is the best in the market. Next Saturday I will go to the range but any of you had used this in this type of AR Pistol ?

Great product - Marvin

Running this as an H2 in a 10.5 inch pistol, with a flash can, in 7.62x39. Flawless and perceived recoil is on par with a 5.56. Kick ass product!

exellent - Teemu

Very good product.....

May 21st, 2018

Excellent - Mhmjr

Running this as an H2 in a Hardened Arms 10.5 inch pistol, with a flash can, in 7.62x39. It is flawless and the perceived recoil is on par with an M4 in 5.56. Great product.

Twang is Gone - Keith

I was somewhat surprised my REC7DMR (556) was so noisy and twangy every cycle. Just sounded cheap. Threw this spring in and problem solved. Runs far more quiet than before.

It's a good product - Dirk

I put this in a Colt rifle that has a 14.5 inch Colt socom barrel on it. It was already perfectly gassed. I can't say it improved the recoil pulse any. There isn't that rusty trampoline spring sound anymore, though. The ejection pattern may have shifted from 3:30 to a strong 4 oclock position, and makes a smaller pile of brass. You can definitely feel the increased resistance of the spring when charging the rifle. I think this is best suited for over-gassed rifles. Otherwise, the jp tuned and polished springs are good enough for "twang" removal. Typical outstanding Geissele build quality. Satisfied.

April 21st, 2018

Excellent combination - Will

Ordered the tungsten weight as well to help calm my MK12 builds over gassing problem. Worked like a dream. Noticeable felt recoil and slowed the carrier down. If you need a spring and buffer look no further.

Flawless - Even 300 Blackout Suppressed - David

I simply don't build or own an AR15 without this buffer and spring combo. Hands down the best improvement you can make to your firearm. I routinely shoot 300 Blackout suppressed with this product FLAWLESSLY. I haven't tried unsuppressed but what would the point of that be? Thank you Geissele!

March 28th, 2018

Excelent, a must for any build - Dale

I got one on sale out of curiosity. Well, like all geissele products you wont be disappointed. during the first mag I could tell the rifle just ran smoother than normal. I have about 8 mags through it now it is my favorite rifle, had several others shoot it and everyone noticed the difference in the way it ran. The only problem is now I need to change out the rest of my ar's , maybe Bill will offer a bulk discount. lol

Best Upgrade to my AR-15 - James

Like many who own the M&P 15 Sport 2 is the "springy" feeling you get during the recoil. I changed out the stock buffer spring and tube with the Geissele Super 42 Braided Wire and Buffer Tube. I promise this will be one of the best upgrades and I advertise this product on my M&P 15 Sport Owners Group on Facebook.

March 18th, 2018

Worth every penny. - Somguy-_-

Now I haven't seen a whole lot of reviews other than on this website and like a YouTube video. The moment I put this in and the 1st shot fired it was like day and night. I put 500 rounds through right after that. Fired so smooth, reduction of recoil, cut the sound a good deal.
Just a note, it comes with a H1 buffer but with combination of the spring it feels like an H2.
Aero precision upper, lower jp trigger with bcm bolt in 556.

Excellence at Every Level - Shwell

The Buffer and SPring combination is something many new builders take for granted. Many owners ignore it and believe any buffer/Spring combo will do. In my experience, the occasional Planker may be able to get by. Let's face it, 2 range trips per year isnt going to amount to any substantial abuse.

I am not an occasional shooter, I shoot weekly. I shoot thousands of rounds monthly, so I have experienced stoppages and damage based on improper buffer combos, as well as the effects of using cheap buffer combos. By cheap, I mean "CHEAP"... That $20 combo from the gunshow isnt going to hold up.

The Super 42 combo doesnt fall in that category, and it isnt expensive either. I can shoot my guns with confidence knowning the buffer will not fall apart, or that the spring wont snap in the middle of a 1200 round class. This translate to a buffer combo I am confidently adding to Duty grade firearms.

My Guns cycle smoothly without the "Twang" I have become used to over the years. I am slowly adding this combo to all of my AR's, and the odd chance that I need it to be heavier, Geissele has that covered by offering Tungsten weights. Smooth, Quiet, Affordable, and Effective.

No Twang - Mark

Before I shot my first ever AR build I tried one with a regular buffer and spring, and it felt cheap due to the rattle and twang. I realize this is probably just fine in practice, but my new rifle feels simply awesome by comparison with the Super 42. Hard to believe all that is going on under my cheek with this thing installed. I would say with less distraction it can't hurt my accuracy either. It's going in my 224 Valk for sure.

February 8th, 2018

Good to go - Jose

I ordered the spring and extra weight about 6 months ago for my 10.5 inch Noveske sbr. Rifle already ran like a champ but with the new spring it is even better than befor. Less felt recoil and the chatter in the rifle is gone. Just ordered my second one for my Radian Arms AR.

the best - willie

geissele has done again before mine cabin length gas system and a the annoying sound that everyone hates instill the super 42 spring with buffer the noise is gone and the recoil inplsue almost feels like a mid length with put this in every ar build from now on

January 26th, 2018

the best - willie

geissele make the best product for the price before my ar15 cabin gas system has a petty wired recoil inpulse and makes that anoying noise

Simply Amazing - Jack

I read the reviews and was a little skeptical on the difference that a buffer and spring could make. I was dead wrong, this thing is absolutely amazing. Like most have said, the twang is gone, and my rifle cycles considerably smoother. The ejection pattern is consistently at 4 o'clock now making it easier to collect my brass for reloading. The muzzle doesn't rise at all after firing, in fact it drops now. I'm using the Super 42, H2 buffer, SD3G trigger, and 16" Adams Arms Carbine gas piston upper assy, This rifle is an absolute joy to shoot now. Thanks for the great products Geissele!!!

Geissele Quality - Nate

I have seen many reviews proclaiming the quality and reliability of Geissele products. I had to find out for myself, so I purchased this buffer spring and buffet kit for my Daniel Defense 14.5" mid-length M4. This simple upgrade(investment) has exceeded my expectations! Reliable cycling every time with all ammo types and greatly improved overall felt recoil. My next investment will be a Geissele SSD-E trigger.
I'm proud to have your components

Significant AR-15 Improvement - RobOtto

Colt 6920: this buffer spring and the SSA-E trigger has transformed my AR into a fantastic rifle. Lightens recoil, smooth shooting. Just the perfect balance of perfection (for me).

December 20th, 2017

Simply The Best! - Gunner B

What can I say? Love at first pull. I am a professional trigger puller retired from the US Marine Corps and a current law enforcement officer. I have 25 years of pulling triggers on the AR platform. Smooth reciprocation each time and no more twang! Purchasing one for each of my ARs is my only complaint now. I am glad to see quality US made components which are produced literally right around the corner from where my Mom lives and in the same town where my brother is a LEO.

Suppressed 300blk - Bryce

I have a 8 inch 300blk and it's true it doesn't like subsonic ammo. Unless you run a can, then it runs great. And what's the point of subsonic if you're not using a silencer?

November 24th, 2017

It's too good... - Brandon

I love the spring and buffer and it works better than any regular mil-spec spring and biter I've used. I give it 4 starts and this comment because it bent the tip of my buffer spring retaining pin. Honestly, it is probably that the retaining pin is of inferior quality compared to Geissele products (As most products on the market are).

November 5th, 2017

Great product - Rogerdodger

Smooth and quiet, I followed directions on package and put quality firearm lube on spring , go juice Alg grease , my rifle a Daniel-Defense v7 Lw is smoother now , also my ejection pattern changed a little but as long as your rifle ejects every time it doesn’t matter my rifle now ejects to 330 position with this spring and buffer but I was never concerned about ejection I just wanted a new spring after several thousand rounds through my rifle

Suppressed SBR - V_LVI

Running a BCM 11.5" with a SIG SRD556 QD and Gemtech Suppressed BCG. The Super 42 was noticeably more reliable than standard spring and H buffer which would occasionally fail to chamber a round completely. Did not have this issue with the Super 42. Consider this a must have on DI suppressed.

October 22nd, 2017

Best on the market - Robert

When i purchased my bcm it had a mil spec spring and buffer and wasnt terrible , but had a little twang and just wasnt as smooth as my other rifle with the super 42 , so i ordered my 2nd super 42 and wow what a difference in the smothness of the rifle and absolutely no twang . This is one of those parts that will go in every rifle i own. Thankyou geissele crew for making products that are not only worth every penny but also that i can trust my life with

No equivalent! - OnlyTheTip

This combination will positively impact how the AR15 functions. It virtually eliminates the shortcomings, flaws, and annoyances that other buffer springs suffer from. You will notice smoother cycling, and the undesirable noise is virtually eliminated from within the buffer tube, recoil is also mitigated. In my opinion this upgrade will make a huge performance impact, and is hands down the easiest, least costly performance enhancement available on the market.

Best in the market - Ken

I built a lower and use nothing but GEISSELE lower parts kit mil-spec and purchase the ALG COMBAT TRIGGER ALF Defense, and purchase a SUPER 42 BRAIDED WIRE BUFFER SPRING AND BUFFER COMBO, totally happy with my purchase best trigger I have ever used the super 42 buffer spring is the best out there what a difference Bill GEISSELE and his team and engineers , are the best in the business for high-performance triggers and accessories for mil-spec rifles a 5 star rating********************

A tank - Robert

This spring and buffer are built like a tank , and you can really feel a difference

June 20th, 2017

Best Spring Ever - Andy

This thing is like nothing out there. Spring noise gone, less recoil, greatly improved feeding etc. No enough good things I can say about this combo. They always seem to impress me. Buy immediately if you are looking to purchase. As always, Another excellent product from Geissele.

June 18th, 2017

The best spring I've used - Aaron

I put the Super 42 in my 16" carbine which is horribly over-gassed. I swapped one of the steel weights with a tungsten weight I had in another H buffer I had laying around to make it an H2. All I can say is wow. I can not believe what a difference this made. The rifle now recoils straight back into my shoulder and the muzzle doesn't jump like it used to. The only problem is that now I need to buy them for the rest of my rifles.

June 10th, 2017

Excellent product - Robert

Nice smooth recoil impulse, no twang . Exactly what there described to do

June 9th, 2017

Great for Suppressed Guns! - Paul

I was running my suppressed BCM 11.5" SBR in a carbine course and it had gotten very dirty. After awhile it began having issues chambering a round after performing a magazine reload. It was just VERY SLUGGISH and I'd have to hit the Forward Assist in order to get the bolt to go all the way forward and chamber the round. This was with a standard H2 buffer and recoil spring.

I then realized I had a brand new Super 42 spring and buffer combo in my car, so I swapped them out.

Once the Super 42 was installed, there was IMMEDIATE IMPROVEMENT!! For the rest of the evening and night I had ZERO issues with my carbine failing to chamber any rounds. The Super 42 just has more force behind it and it loaded my magazines of 30 rounds just fine.

The Super 42 performed perfectly and I bought several more immediately afterwards!

June 6th, 2017

Great combo for SBR - Justin

Purchased the spring and buffer in an attempt to tame a 11.5" SBR. Added an extra Geissele tungsten weight to make the buffer H2 weight. Noticeably smoother shooting than the standard carbine spring and H1 buffer that the SBR came with from the factory. Haven't found a factory .223/5.56 round it will not cycle reliably. Thumbs up emoji.

April 16th, 2017

Very Nicely Done!! - Tyler

All I can say is WOW!! I ended up swapping out my mil-spec buffer/spring combo on my Colt LE6920 and what a difference!! Geissele did a wonderful job in taking something as simply as a buffer spring and making it a work of art.

April 12th, 2017

Great Spring, NEEDS RIFLE BUFFER COMPATABILITY!!! - Frankie 2 Lunch

This spring works fantastic in carbine buffer system as designed, and has allowed reliable feeding with steel case ammo with cheapo PSA Upper and Lower and lowest price PMags. Since installed with Super 42, has reliably fed 330 rounds of TulAmmo 62 gr FMJ. Also noticed little to no "scraping" sound inside buffer tube when pulling the charging handle. Gone is the sound of the infamous AR15 "Cheese Grater."

Only thing we need is a version for rifle buffer tubes. Weather or not all that would require is a new buffer or if that requires a new weight of buffer spring is unknown to me. After experiencing the quality and performance in bother this buffer spring and my SSA-E trigger, I am fully confident that these people can figure it out.

Keep it up ladies and gentlemen. Appreciate the quality.

March 13th, 2017

Simply The Best - Joe

Only Bill Geissele and his team could make a buffer/buffer spring a thing of beauty. It's a shame this thing is hidden away inside the receiver extension! The recoil impulse in my 16", mid-length RECCE type build completely changed, for the better. Muzzle jump disappeared, absolutely zero spring rattle or twang and my ejection pattern went from 2 O'clock (running M855) to 3 O'clock. I was able to stay on target much easier and snap off follow up shots quickly and accurately. If you're looking for the solution to today's typically overgassed ARs, this is it.

February 5th, 2017

Regrets...I've had a few - Capo

Buying this is not one of them. Not buying MORE of them for all of my ARs is. I just received mine in the mail today and have dry fired a few snap caps just to get the feel for the spring/buffer combo. This is incredible, even without actual live firing I can tell that this just feels right. Thank you for another great product

December 4th, 2016

The best buffer/spring combo available! - James

I had been on a search to find the ultimate buffer and buffer spring for my AR-15 build. I found it. I've known about twisted wire springs for a long time and was hoping someone would make one for the AR-15, leave it to Geissele to bring it to market. For a buffer spring application twisted wire is superior to round and flat wire due to it's dampening qualities and extreme durability. The increased spring rate of this spring helps to eliminate bolt bounce and stripping rounds from the magazine, especially with steel cased ammo. I really can't say enough about this spring and buffer other than your AR needs it. Thank you Geissele!

December 2nd, 2016

Absolutely perfect - Michael

I had been looking for a spring/buffer combo for a new build. This is perfect, no spring noise, sends the bolt carrier group home every single time without the slightest hiccup. I only put the best parts into my guns and this is not only the best spring I have ever used but the price for both the spring and the buffer you just can't beat it. Well done Geissele, yet again another fantastic product.

September 30th, 2016

Typical Geissele! - Dave

Another great Geissele product! Works flawlessly and with much less spring noise.

July 30th, 2016

Well made - Mitchell

Very well made product. The finish on the buffer is even. The spring feels very smooth.
This helped my rifle cycle wolf and tula much easier.
I recomend it!!
