Questions & Answers
Will this work with a AR-9 Glock Mag platform? Expert Answer

The Geissele Maritime Bolt Catch works with Mil-Spec dimension AR15's and may not be compatible with Billet receivers according to the manufacturer. So if your AR9 is Mil-Spec dimensions it might work.

Function good - damaged my BCA 300BLK Upper by Dave-in-Texarkana, Verified Owner, February 24, 2026
This installed and functions well. My son has several and really likes them as why I tried this. One caveat and the star off, the 'flying boat tail', to the right of the upper release button as you look at the release straight on, is very wide. It...

Favorite Bolt Catch I Own by DM354, Verified Owner, January 6, 2025
I prefer this over any standard bolt catch as well as the bolt catch on my Daniel Defense. Pretty inexpensive upgrade to make life easier.

Perfect solution by Mark Guy, Verified Owner, August 20, 2024
The second flaw of my left hand Stag Arms AR-15 was the pitifully small bolt catch. The Geissele Maritime rectifies the issue of locking or releasing the bolt with your left index finger. The paddles are effective without snagging clothes or interfer...

Great Product but Not with Ambi Mag Release by robsrobbies, Verified Owner, March 29, 2022
I bought several of these and several Ambi mag releases. Except for my PSA, I could not use this product and the Ambi mag release together. You have to decide which you want. One other negative is that it comes with the lever and roll pin. For the p...

Improvement but at a cost by Packy14, Verified Owner, June 27, 2022
Just installed this.... but it is a huge pain in the butt to then change a trigger... especially if its a Geissele and you use their roll pin technique... because this will prevent you kicking out the small roll pin... you can only insert and remove ...

Product Info for Geissele Maritime Bolt Catch

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.image
