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.

Helpful Positive Review 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...

Helpful Positive Review 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 ...

Helpful Positive Review Best $30 Buy for AR by Theodore, Verified Owner, August 10, 2023
This thing is pretty cool as the added real estate on the catch makes up for sloppy hand work by me. The knurling is substantial and helps out too. Like everything else made by Geissele, this is quality.

Helpful Positive Review Great upgrade! by Patriot Medic, Verified Owner, March 6, 2023
This is an awesome product to upgrade with for not much money compared to other upgrades. Gives a very generous amount of surface area on both sides of the lever. Not as necessary on the lower portion but having the extra surface on the part you use...

Helpful Positive Review Best of the best by Orin, April 5, 2023
It's a bolt catch. Made by Geissele. You really can't get any better. Easy install, Looks fantastic, and functions flawlessly. Just spend the extra $ it's definitely worth it. Need more words so blah blah blah......

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
