Add To:

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 faster 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.

This works on my ar 10 lower?
Miguel Martinez on Apr 14, 2019
BEST ANSWER: Yes I have it on my dpms AR10. Pretty much all inside lower and outer components in a ar15 are compatible on a AR10 so long as it has nothing to do with the mag well or buffer system.

I Like It!
The standard AR bolt catch is very functional but this redesign makes clearing type three malfunctions easier because it is easier to lock the bolt open. Other companies make a bolt catch release that is an improvement on the original design as well. They are less expensive...I have a Geissele trigger and it has been terrific, I chose this release because I trust the Geissele brand to deliver durable, functional and superior performance.

I'm glad I made the change.

Must have part!
Fantastic addition to any ar. The only thing I dislike about this, is having to buy one for every one my past and future builds.

Does what it does
The Geissele Maritime bolt catch is huge. Seriously, it seems massive on my rifle.
Worth it? We’ll see. I’ve not taken a class with it yet.

Great upgrade, looks nice. Interferes with the hammer pin though.
Great bolt catch, much more surface area. It DOES interfere with your hammer pin on the left side if the receiver. I notched mine with a Dremel to clear it, but you could just remember to push the pins out to the right too.

I like this very much. Positive contact when locking the bolt back or releasing it. Works I would recommend it for anyone that's looking to have a larger surface for the bolt release.
