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.

Seems made for the Sharps Bros Billet Upper! Perfect match!
Seems made for the Sharps Bros Billet Upper! Perfect match! I've outfitted both of my Sharps Bros Billet Uppers with this maritime bolt catch. It seems absolutely perfect match for this upper. Highly recommend.
USOutstanding Performance
This is an outstanding addition to a tactical or competitive layout. Ideal for one-handed, no-eyed, stress operated and non-dominant operations set-up. BE ADVISED: Right-left forward trigger pin removal is compromised with this device in place (e.g. field reduction of blown cartridge casing). I found easiest fix is using a threaded anti-walk that can be backed out from the right. There is enough room to remove a retaining screw. That is the ONLY hiccup to an otherwise “why on earth isn’t this the standard on every AR?!” product (AND AR15 DISCOUNTS IS DEFINITELY THE BEST PLACE TO BUY IT!).
USAR-15 Lower Parts Upgrade with Geissele
I’ve been slowly upgrading parts for my 6.5 Grendel rifle and was happy to add this Geissele Maritime Bolt Catch. It has a great feel installed easily and it pairs nicely with the Geissele SSA-E trigger this lower has.

USA must have
Like the title says, it’s a must have for any AR I own. Do you need it, in reality no, the standard mil spec catch has done the job adequately for generations. But once you try it out, it’s one of those parts you wonder where it’s been all your life. And like every other “G-man” product adds some flair to your rifle.
