The Geissele Maritime Bolt Catch gives users larger, easier-to-reach controls for faster bolt lockback and release. It fits any lower receiver built to accept a mil-spec M16/M4 bolt catch and increases the contact area to make function smoother when locking the bolt or releasing it after a reload.
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:
- Fits mil-spec M16/M4 lower receivers
- Larger contact area
- Aggressive checkering
- Made from heat-treated 8620 steel
- Manganese phosphate coated
Extended levers improve ergonomics for left-handed shooters, letting them operate the catch with the index finger of the support hand for fast and efficient use. Aggressive checkering on the levers provides positive tactile feedback when wearing gloves or working in low light. Made from heat-treated 8620 steel and finished with a manganese phosphate coating.

The only bolt catch choice for me. *GEISSELE please include the plunger and spring*
by Aaron -
I use this bolt catch for ALL AR builds. Great fit and function. The only detractor I have is Geissele needs to include the plunger and spring with it in one kit. I can't tell you how many times I've forgot to order them when I buy one of these.
Far superior to tennis racket
by Kentucky Hot Brown Spring Roll -
A lot better than the traditional bolt stop. I like how the crunch roll pin is a little oversized. I know some purist go for the flush fit, but it makes installation easier. The only down side is trigger install/re-install might be problematic.
Great, but will not fit Tippmann rifles
by Capt-J -
To help with my little T-rex hands, I paired this beautiful Geissele Maritime bolt catch with a Troy Ambi mag release for my Tippmann AR style rifle. There was no interference between the Geissele and the Troy. Normally that would be the end of it. However, when I re-assembled the upper, I found that the stock bolt catch was proprietary to Tippmann rifles, and the Geissele bolt catch would not function. So, except for Tippmann rifles, the Geissele Maritime bolt catch is great. Primary Arms customer service was great - no problem with the return.
DON'T FORGET TO ORDER PLUNGER AND SPRING
by AaronC
As a lefty, and for anyone else, this is my go-to bolt catch for all builds. Just be sure to order a plunger and spring for new builds as this only comes with the roll pin.
If you use an ambi mag release, this could interfere with that, but you can trim the bottom of the catch and repaint it as other have suggested.
nice upgarde

i replaced the bad lever with this, in my opinion this bolt release from Giselle is much better and looks nicer
Works perfectly

Lil big and kinda bulky but works great and this thing is tough
The only bolt catch you need
by Dan
This bolt catch is amazing, well made, and functions perfectly. Love the extended surface area top and bottom, makes charging the rifle a lot easier. The textured surface ensures contact is unmistakable, no more fumbling my hand around like with the mil-spec bolt catch my AR came with from the factory. Even when it's a part as small as this, Geissele is capable of showing off its superior designs and craftsmanship.
Works as advertised.
by Mike -
Excellent finish as expected from Geissele. Requires minor trimming to clear hammer pin removal on milspec lowers along with the fact that it is a little over priced drops score to 4 of 5 stars.
AWESOME!
by Ed B. -
Easy install and is a great addition to any setup over the Mil-spec option.
Awesome upgrade
by Cory
I've used this bolt catch on 5 AR-15 build to date and have had no issues whatsoever. Works well with the Troy designs ambi mag release as well as the CMC trigger with anti-walk pins. Though it can be a bit finicky installing the anti-walk pins if this bolt catch is already installed.
Only issue I've run into so far with them is that they are not compatible with the Aero Precision M5 lower receiver. It will fit just fine on it, but there isn't enough room on the receiver for it to raise the bolt catch as needed. This is the only type of lower receiver I've tried it with so it may fit others just fine.
Other than that small issue, they're a solid upgrade to any AR-15 lower that I've come across.
