Maritime Bolt Catch

$29.00

The Geissele Maritime Bolt Catch is designed with the warfighter in mind and will work with any lower receiver designed to accept a mil-spec M16/M4 Carbine bolt catch. The increased surface area promotes ease of function when locking back the bolt or releasing the bolt after a magazine change. In addition, the extended controls add an increased functionality for left handed shooters who no longer have to break their grip to manipulate the bolt catch. Left handed shooters can easily reach the controls using the index finger of their left hand making magazine changes and locking the bolt back much more fast and efficient. Aggressive checkering covers the surface of the levers giving the Geissele Maritime Bolt Catch a textured surface that enables positive feedback to the shooters hand when being used with gloves or at night. Manufactured from properly heat treated 8620 steel and manganese phosphate coated, the Geissele Maritime Bolt Catch is intended to serve as an enhanced mil-spec replacement and assist in giving our warfighters overmatch capability with the M16/M4 carbine platform.

Please Note: A mil-spec bolt catch spring and plunger are required for assembly and are NOT included.  If the Maritime Bolt Catch is replacing an existing mil-spec bolt catch, please use care when disassembling the component from your lower receiver as you will need these parts to install the Maritime Bolt Catch.
Compatibility with billet AR-15 lower receivers is unknown. Please also note that the extended controls of the Geissele Maritime Bolt Catch will partially cover the pin hole for the hammer, a smaller punch may be required to push the hammer pin out of the receiver from the left side, and the hammer pin should only be installed from the right side of the receiver.

Incredibly well designed - Mark

The best Bolt catch on the market. Large paddles are super easy to manipulate. Fits Aero enhanced uppers with threaded pins. Installing them as default on all LEO upgrades.A must have item

Outstanding. Love it. Need more. - *Moose

I no longer serve but wish I had this when I did. If someone asked me to design the ideal bolt catch for my use/experience, this would be it. Will be picking up several more and giving them to friends/associates.

A nice upgrade - Scott

I purchased 1 for my M4 to see how it worked based on other Geissele products I have used. After using it a few times on the range and seeing that it made mag changes easier without having to concentrate so much on "hitting" the catch just right. I decided to buy another for my SAR. Friends who have used both loved the bolt catch and ordered their own. Definitely a worthwhile buy

Works with Norgon Ambi-Mag Release - Dale

Geissele makes great stuff and this is no exception. My only concern before ordering the maritime bolt catch was that I wasn't sure if it would work with the Norgon ambi-magazine release installed on my lower. Rest assured...they work great together. Well worth it.

AR10? - JEFFREY

Do you plan on making an AR10 model? Thanks

Great product, but one detail - grant

The catch is very nice and well machined. Fits great. My only gripe is the bottom paddle is large enough to prevent driving the hammer pin in through the left side. This isn't a problem with the higher-end Geissele triggers and mil spec triggers which can be installed from the right side. The only problem is when using it with the Geissele g2s trigger which needs to have its hammer pin driven in from the left side due to its pin retention design. Otherwise, when you drive the pin from the right with the g2s you have to clear two grooves in the pin to be retained by the third groove. Not a big deal at all, but it is a detail to consider. Fortunately I have a threaded bolt catch pin. It seems to me the product could be improved by removing an 1/8inch or so from the bottom paddle, to increase its compatibility with other Geissele products.

This is the one - Alain

very easy to install and works great

Southpaw upgrade - Roger

This bolt catch is a major improvement for a left handed person. You can now operate the bolt catch and bolt release with your left index finger. For those who've trained to operate a pistol slide release with your left index finger you'll find this upgrade right up your alley.

Install was fairly straightforward, ended up knocking out the old roll pin with a 3/32" flat side punch; this is a very tight fit. Installing the new roll pin was easier with a standard 5/64" roll pin punch despite the punch being one size too small. You can get these punches for pretty cheap straight from wildetool.

Best on the Market - Tyler

As an ambidextrous shooter, I love the ability this gives me to reload and lock the bolt to the rear with my left hand.

As someone who likes to go fast, I appreciate how much easier it is to send my BCG into battery while shooting right handed.

Excellent product! And detailed instructions, as always.

Nice add on - Adam

As a Tactical Bomb Technician operating with a SAWT element this makes it easier for me to clear the weapon especially at training with drills. Great kit at a good price.

Perfect bolt catch - Robert

This is the sec maritime bolt catch ive purchased for a new bcm build and once again its the cherry on top , easy manipulation , great looks and built like a tank every ar i buy will get one of these

Just buy it! - Juan

This bolt catch is amazing. I expected nothing less than Geissele perfection! Great size and nice feel and a perfect price.

Almost there - Frank

Concept is great. Works well. But ... the bolt catch pad should have the aft 1/4" removed to facilitate access to the hammer pin for removal

**Geissele Response: The hammer pin can be removed with a punch, it simply needs to be pushed out of the opposite side of the receiver.**

Best upgrade yet - Robert

I love my geissele trigger , but this bolt catch is perfect no searching or slipping , easy manipulation left or right handed , buy it

Like No Other Bolt Catch - Andy

This Maritime bolt catch is like no other on the market. Has great grooves and perfect finger handling regardless of left or right shooting. Excellent craftsmanship as always from Geissele. Looks awesome and fits like a glove. Highly recommend to anyone looking for a different bolt catch with Superior handling. Thank you Geissele

A great idea and functionally perfect but... - Peter

The Maritime Bolt Catch, as you can see, has a much larger footprint both for catch and release (no, you can't fish with it). The knurling on it is fantastic and it will be extremely grippy with naked hands or gloved. It feels more "positive" in the mounting slot than both factory catches I replaced with it. There is literally zero wobble like we see with the standard mil-spec catch sometimes. I feel very comfortable saying that I initially like it after dry fire practice over the last three days but I'll have much more to say after a few weeks of running it. There is in my humble opinion, one flaw in the device though that bothers me quite a bit but would never keep me from running it and that is the shape of the top of it. It absolutely looks like an afterthought. I mean, this thing could have been any uniform shape that allowed for lefties to reach it without breaking their grip. A simple rectangle would have been great. This thing looks like a placid penis or a drooping booger. But, alas, I will continue to run it as it just works and it works well. Thanks Bill.

Awesome bolt catch - Robert

Fantastic - Tim

I always fumble with A bolt catch even after over 40 yrs using one. Tried strike extended bolt catch. But bought ones these the instant I saw it. Easily installed. Fingers find and can operate this with ease. Even tried with gloves. Will buy others highly encouraged. Thanks

Really nice product - crabbysam

This bolt catch is exceptional, I've tried more than a few bolt catches in my day, they're really too big, to small, or both. I missed the big sale on these, so I bought one at DSGarms as they afford me a retired MIL discount.

I liked it so much I came back here to order one for every AR I own. Free shipping is always appreciated.

This Maritime bolt catch is just the right size and well made. Geiselle engineers got this one right!

Quality - Eric

Impressive in both form and finish. Every bit of the quality you have come to expect from Giessele. I am a left-handed shooter who has been handling AR’s for over two decades and this design is a great improvement over the stock bolt catch.

May 27th, 2017

Greatly Improved - Charles

The Maritime Bolt Catch is a superior design to stock or original M4/AR bolt catch. Machined perfectly, fit perfectly, functioned perfectly per Geissele's usual craftsmanship. The Maritime Bolt Catch offers the end user a much easier bolt catch to manipulate regardless of left or right handed, gloved, or bare handed. I would highly recommend to any user that needs every part of their M4/AR to exceed and excel when it counts.
