The Redi-Catch allows for the bolt to be locked open by pressing the
magazine catch with the trigger finger while pulling the bolt back with
the left hand. The result is a more ergonomic and rapid bolt lock back.
Because of the elasticity of the spring steel wire, the magazine
catch button can be depressed at any time or the entire time the bolt is
being pulled back, as the bolt catch paddle can move through the
different stages of the cycle.
Unlike existing devices, the bolt catch activation timing becomes
irrelevant and the reliability of the bolt catch engagement is at
Installation is a breeze. Simply remove the existing magazine catch
and replace with the Redi-Catch. Then place one end of the "S" shaped
flexible spring steel wire in the Redi-Catch hole and making sure the
wire is in the groove near the top of the Redi-Catch post, place the
other end behind the bolt catch paddle.
Please note that with the Redi-Catch installed, the pressure required to
press the magazine release button is increased (both the mag catch
spring and bolt catch spring are being compressed), We do not consider
it a negative or compromise in light of what Redi-Catch offers to the
user, rather an added feature to mitigate accidental/unintentional mag drop.
Depending on the receivers, Geissele Maritime Bolt Catch's lower paddle's lower edge might need to be filed to clear the mag catch.
