First Claim
Patent Images
1. In a repeating weapon of the class having a frame, a receiver, a barrel, a bolt, a bolt carrier, a gas cylinder ported to the barrel, a as piston connected to said bolt carrier slidably fitted into said gas cylinder to be shifted in one direction by fluid pressure in the cylinder, and an actuating spring opposed between said frame and said piston to shift said piston in its other direction, the improvement comprising:
- said spring being a coil springa spring guide in lateral-restraining relationship with said spring, said spring guide enabling the distance between the gas piston and the frame to vary, one end of said spring being attached to the piston, and the other end being releasably anchored to the frame and being bendable to permit the end of the spring that is opposed to said frame to be raised without raising the bolt carrier, said bolt carrier centering the spring, and having a slot therethrough to pass the spring laterally.

Abstract
A repeating weapon in which its bolt carrier is slotted to enable an actuating spring to move laterally, carrying with it a gas piston. The spring is anchored to the receiver in such a way as to be anchored or released by axial movement. This enables a quick and simple field stripping sequence.
