Geissele Maritime Bolt Catch - 08-153
In stock
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. 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.
Please Note: A mil-spec bolt catch spring and plunger are required for assembly and are NOT included. If the Maritime Bolt Catch is replacing an existing mil-spec bolt catch, please use care when disassembling the component from your lower receiver as you will need these parts to install the Maritime Bolt Catch.
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 pin hole for the hammer, a smaller punch may be required to push the hammer pin out of the receiver from the left side, and the hammer pin should only be installed from the right side of the receiver.

Bolt Catch
The bolt catch has great quality, very large pads which is perfect for what i was looking for, only issue was that its more of a flat bolt catch, 180° from the top pad to bottom, vs most which seem to be about 210° clockwise. This causes an issue on aero m5 lowers which was my intended purpose for this bolt catch, but i will be installing on my palmeto instead.

Good oversize bolt lock.
It is my second one. It fits what I need and how I like.
USIt’s big enough
Does what it’s supposed to do. Makes it easy to engage bolt from locked position. Looks durable. Nice flat black color. Deep serrations to keep your fingers, gloved or not, from slipping. I like the bottom part of the catch the best. No more puny push nub. Now it’s easy to slam the bolt into battery.
Geissele Bolt Catch.
As other reviewers have stated, the supplied pin is too big to go through the hole in the bolt catch. I reused the original pin, no problems. The bolt catch works very well. Good, large surface areas for manipulating the catch.
USGreat piece
Functional as it should be. Makes things a bit easier to reach
