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.
