In addition, the extended controls add an increased functionality for left handed shooters who no longer must break their grip to manipulate the bolt catch.
NOTE: Required MIL-SPEC bolt catch spring and plunger are not included.
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 hammer pin hole. A small punch may be required to push the hammer pin out of the receiver from the left side, and the hammer pin must be installed from the right side of the receiver.
Features:
- Heat treated 8620 steel.
- Manganese phosphate coated

Great size
by James -
I use a few of these.
Be aware: The billet receivers are sometimes cut around the bolt catch and this G.A. is a wide fit.
It works perfectly on forged receivers. It is still on the larger side. I haven't done it, but I can see where it could be a snag point, but still it's a 5 star no brainer purchase.
Love it but

It does not fit in the BRO Tyrant.
Good for me
by Vincent -
I've heard about these breaking on people due to them being cast and not billet. However hasn't happened to me.
Something to consider...
Works great!

Another Geissele great product!
Super
by Allen
I run these on all my ar rifles. I'm left handed ,so a little twist of the hand and I'm right to the switch to drop the bolt. Speeds things up in three gun too. 👍
Top notch
by Kevin
Hands down best bolt catch on the market, I get one for every build, love the texture and large surface area
Not compatible with Forward Controls ambi mag release
by Matt
Quality materials and great value - but as the title says, not compatible on a rifle that has the Forward Controls ambi mag release installed unless you want to modify this with some grinding.
Almost 5 Stars
by Mark -
The Geissele maritime bolt catch is almost 5 stars. The one major flaw is the lower paddle for the bolt release is so wide that it blocks the trigger pin from being pushed out. The quick work around is to grind the edge down so its not as wide but for being Geissele they should have already known this and made it a bit smaller. Even with this minor flaw, all my rifles have this bolt catch. Definitely recommend this product.
Won't fit Aero AR308 Lower

Although this item comes up when searching for AR10 parts, it will not fit a Aero Precision M5 Stripped AR-308 Lower Receiver - DPMS Cut
My Favorite Bolt Catch

Well built, good quality. Doesn't fit with every upper but I put it on everyone it will fit on.
