Fantastic Trigger - Charles

I cannot imagine how any trigger could be better. Many have said breaks like glass. I can't dispute that. Will be buying more

Fantastic 2-Stage Trigger - Breaks Clean and Predictable - TMHGator

The Geissele 2 Stage (G2S) is a fantastic trigger. I put one in my new Mossberg MMR Hunter and zeroed my optic 2 weeks ago. I dare say if I would have left the crappy mil-spec trigger in this rifle, I would not have been able to achieve 3/4 groups consistently at 100 yards with this rifle. Deer rifle season in my State opened this weekend and with this rifle I easily filled my two doe tags with two large healthy does at a little more than 100 yards. I love this trigger and will put more of these in my other target/hunting purposed AR's.

AR built - Steve

My first AR built, use the G2S two-stage trigger after 150 rounds it shot flawlessly. Easy to install crisp clean trigger pull. I emailed for technical information they answered quick within days. Would recommend this to anybody for either upgrade or their first built.

Oustanding - Aaron

If you're holding back because of the price, dont! This trigger will be the greatest investment for your ar platform. For the price it's well worth it for the performance given.

Can't go Wrong - Ben

Ordered this as a college student... took me awhile to save up. I was considering forking out a little extra for the SSA but opted to go with the G2S as I knew it would be a significant improvement over the stock trigger in my DPMS carbine. Boy was I right!

Smooth as can be, and I was wondering how the 2 stage would feel during "rapid" fire and you don't feel a wall of any sort (probably because the stage 2 weight is lower). The whole weapon feels higher quality, like driving a cavalier and going to a Ferrari.

I will admit, however, the installation was a little tricky. Getting that hammer pin in was a heck of a job which required some elbow grease and a hammer wrapped in a leather glove, but at least I know it's not going anywhere. You get plenty of oil with it too, which is a plus. I don't think the "fitting pin" was really a necessity but being new to all this they got me there. I would've just used a regular punch. Would be nice if there was a slave pin to keep it all aligned when you throw it in but not too bad.

For God and country!

WOW What a Difference - Charles

Read about them, now that I shoot the G2S trigger it now needs to go in all my AR platforms. This is an easy install. Watch Mr. Geissele's install video and have the tool or a correct size punch and you can do this. This improved my shot group. Thanks for all the swag too.

About triggers - Gary

If I had known about Geissele triggers before I bought two timney soldiers I never would have them there good triggers but there not Geissile, I'm going to try and sell one of them to a friend a but the G2S, my son bought one for his MMR and a friend of mine bought the SD-C I installed both of them easy as pie both a great triggers anyone reading these buy Geissele triggers you won't be disappointed. I give it 5 stars but it will only let me give it three.

Excellent. - Christopher

This trigger is just... wonderful. The reset is distinct and short. The break is so crispy clean. Takes all the guess work and anticipation out of it. Would recommend it to anyone looking for a quality built, reliable trigger for long range, plinking, damn near anything you want to do with it. Great job Geissele.

Great Trigger - James

I ordered this trigger as a poor college student not wanting to spend $250-$300 on a trigger. I was not let down at all. This is a fantastic trigger for anyone except maybe a match shooter. The G2S exceeded my expectations. They threw in a free swag pack with my order and I was expecting a couple stickers. I got multiple stickers, patches, and a black "G" logo hat. I looked at the prices and it was about $25 worth of free swag including the 45th President sticker that isn't sold on the website. This was my first experience with Geissele and after being able to feel the quality first hand and how much this company cares about its customers through the swag, I will definitely be buying more Geissele products and recommending them to everyone.

It surprised me - Kyle

I have had a super tricon in the past and now have two sd-e triggers. I am not sure if I got lucky on this one or what, but I swear this feels almost as crisp as my sd-e. I was expecting it to feel like my old tricon, but it doesn't; it feels better. It is smooth and there is no slight creep in the break like my tricon had. Picked it up on sale, couldn't be happier for the money!

Thanks Mr. Geissele ! - 7th-11B

i think it's fair to say Geissele makes some of the best triggers in the business . what impresses me about this company is the fact that Geissele didn't forget "the average joe . " i'm not rich, but i enjoy nice things just like everybody else ! i picked up (2) G2S and (1) Rapid Fire triggers on sale . now this average joe gets to enjoy a quality trigger . Thanks Mr.G .

No Difference - Tom

Just got it installed in my sbr and seriously thought it was my SSA-E. This is one reason I love Geissele products, even the inexpensive ones are top notch.

November 14th, 2017

Pretty Good - Brad

This is my first Geissele and although it's the cheapest version they offer I find it to be very smooth and the reset is excellent. That said, I replaced a POF single stage which was noticeably heavier although rated at the same overall pull weight. However, since installing the G2S I have had some failures to fire. I can't definitively say that its specifically related to the trigger but the POF hits noticeably harder than the G2S and I never experienced a failure to fire with the POF. Regardless I intend to try one of the straight trigger options offered in the near future. I like free stuff although I only found use for the trigger pin tool and gave everything else away. For the price when it's on sale I would absolutely recommend trying this trigger.

Great Trigger - Joe

First stage is smooth, the second breaks like glass. And gets better every time I go to the range. Also the folks at Geissle was Great to contact me on my Veteran Discount. Plus the swag was truly appreciated.

OK but not excellent - Hauptmann

After receiving the wrong trigger component and getting a replacement, G2S was installed into my AR-10 .308. While better than the Armalite trigger, this pull's second stage is noticeably draggy before drop off and I would not buy another for any scoped rifle. I have one of the Geissele higher priced trigger units and the difference is night and day. While several buyers seem as pleased with the "swag pack", I would have been better served with a crisper trigger.

August 10th, 2017


Price, performance, quality and to me most important, reliability. You can't beat this trigger. That is not my opinion it's a FACT. Swag pack was great as well. Best company to do business with.

how every AR trigger should be made - bill

bought this for my dpms oracle, helped but gun was not worth keeping. then put it in an early bushmaster and that made me happy! will probably replace all of my ar triggers now. not too light like a target trigger, just right with full feel of being in control. GEISSELE people very nice and the hat is probably the best i haveever seen!

What a Difference - FirstStateMark

Replaced my mil-spec trigger in my Ruger AR 556 with this G2S. Was very pleased at the range with the trigger pull. Groups on target were closer together then with the mil-spec trigger. Took a little while to get use to the light trigger pull but well worth it. I love the crisp trigger break of the G2S. Very affordable and well worth the money. Instructions were very good. I'm no AR aficionado and had no trouble installing this myself.

Excellent trigger - Autumn

This trigger came in the mail faster then expected which is a great testimony to Geissele's customer service. The trigger itself is crisp and has a clean reset each and every pull. My swag bag was better then I had hoped for, hat, patches, and stickers. I will be doing more business with geissele in the future.

Easy install - John

Had this in my DPMS AP4 within an hour including making my own trigger slave pin from a 10p nail. Hammer install tool included with Black Friday deal. Trigger is awesome in function as two stage nd soooo smooth. Buy it!

Best upgrade over milspec - Jake

This trigger replaced an ALG ACT Milspec trigger which was excellent, however always felt the rifle was capable of better accuracy. The range trip today verified it. Another order for a second rifle was placed ASAP. This is a great trigger over milspec.

August 6th, 2016

The very improvement my rifle needed - Jake

Received my 1st order yesterday and immediately placed another for a second rifle before ever hitting the range! The range visit with the G2S was a vast improvement over the heavier (but excellent) ALG
ACT milspec triggers. My experience was after shooting a relatively nice MOA group I would have a flier. Well not any more! With good rifle components expect MOA or sub MOA with this trigger!

GS2 - Paul

My 1st build I bought the SSE what a trigger, so smooth. Later built a AR pistol and was undecided on the Geissele or the LaRue. The LaRue was a $199.00 "I need it now", or $95.00 I can wait, but turned out the wait was like 90 days from what I was told.
The GS2 is no comparison to the SSE but for the money spot on. Yes went with the Geissele.

G2S in a DPMS - Aldo Rain

this here trigger is nice
very easy to install
this Geissele fella seems to be pretty smart

Vast improvement over factory - Rocky

I received this trigger within 5 business days. I am very happy with what I got. The G2s installed in less than 15 min, and the swag pack was a great touch. The trigger is great compared to the factory trigger. The only thing I could think of to compare, is driving a Pinto vs a Ferrari.

February 10th, 2016

Excellent trigger. Great value. Smooth as silk with clean break. - Jeremy

Installed this awesome trigger on my Ruger AR 556 and I couldn't be more happy with this great upgrade from the factory trigger. It's smooth as silk through both stages and the break is crisp and clean. Great value for such a quality product without breaking the bank. Highly recommend for any long gun platform. The swag pack that came was also a nice plus. Geissele keep up the great work with awesome products.

January 18th, 2016

Exactly as promised,..AWESOME Trigger ! - Douglas

I recently bought the G2S trigger and wanted to wait til' I tried shooting it with ammo, on targets, a couple of times before writing a review.
I shot MOA and sub MOA with 2 different handloads @ 100 yards in my new Adams Arms piston 16" Carbine with 1-7 twist ( using 50 and 55 grain bullets).
Can't wait to try 65 and 69 grain bullets! the G2S is fairly easy to install and comes with good directions,.. LOVE this trigger !

December 20th, 2015

Nothing is better - Chayson

I bought 2 of these triggers to finalize that I no longer have a AR platform that doesn't have a Geissele trigger. This is a great trigger to replace a carbine mil-spec trigger. I'm still confused how a 4.5lbs trigger pull feels so amazing. When the 1st stage gets taken up there is only that 2lb 2nd stage waiting. It feels better than than any mil-spec with all the polishing and spring kits in the world.

December 12th, 2015

Great trigger plus extras - Christopher

Installation of the trigger was easy. Coming from a standard mil spec trigger this thing makes a world of difference. A little bit lighter, but SO much smoother. Also shot SSA-E on my buddy's AR but this one gets the job done for a lot less $$. Especially since its not a precision/long range rifle. I got this on cyber Monday($115) and Geissiele threw in an installation tool and a swag pack(hat, stickers, and patches) for free

December 10th, 2015

Massive difference for every AR - Nick

Have these in several builds, ran through several classes, 2 deployments....they are indestructible. Picked up on Black Friday for an absolute steal at $115. Installs in 10 minutes with a #8 punch (if you don't get the free install pin).

You could spend $250-$350+ for some Gucci-looking trigger or get this and reap the benefits of flawless production, improved shot-groups and dependable performance. Came with free shipping and wicked swag bag as well.

December 8th, 2015

What a difference... - Jackson

Was really undecided about spending the money on this trigger but when I saw the price drop that did it for me. Easy install and can not believe the difference compared to my trigger even with a swap in the springs. The 2 stage is great an I love the reset for the next shot. Well worth the money!

Great Trigger - Robert

Clean, crisp, best trigger for the money. Install was easy.

Awesome Trigger! - SoCal Shooter

I absolutely love this trigger. I did a lot of research before selecting Geissele and decided on the G2S for my DDM4. The workmanship and quality is outstanding and it's clearly a precision built part that's made to last. Installation was fairly straight forward but you have to read the directions and be patient & precise (it took about 20 minutes). I put about 500 rounds downrange in the 2 weeks since I installed it and my accuracy at medium range off hand has improved significantly. Trigger is smooth and feels great. If you're shooting off the reset, there is no stage 1 which is sweet because it makes follow-up shots even easier. Just ordered another for my other DDM4. If you're interested in making your AR look good, but plastics. If your interested in accuracy and performance, buy a Geissele trigger.

December 1st, 2015

Should have bought this a long time ago. - Michael

Easy install feels great compared to my milspec trigger. I haven't had it at the range yet but I have no doubt I will be pleased.
