Abstract:
The present disclosure provides a buffer kit or assembly for an AR-15, M16, M4 carbine, SR-25, AR-10 and LR-308 type firearm with enhanced fatigue resistance. The buffer assembly includes a weighted buffer, a spring, and a buffer tube. The spring is helically shaped and is formed from multiple wire strands. The stranded wire spring has a greater nominal wire diameter, in comparison to prior art single wire springs, and thus the stranded wire spring itself has a smaller internal diameter. The shoulder of the weighted buffer is provided with a reduced diameter to accommodate the smaller internal diameter of the stranded wire spring.

Claim (Index 7):
A buffer and spring assembly for a firearm comprising:\n (a) a buffer including a buffer housing defining a sleeve portion, a collar portion, and a shoulder portion, wherein the shoulder portion has a first diameter and the sleeve portion has a second diameter smaller than the first diameter, the shoulder portion being located between the sleeve portion and the collar portion; and (b) a helical spring extending between a first end and a second end, the helical spring being mounted to the buffer such that the sleeve portion and the shoulder portion are within an interior space defined by the helical spring and the first end abuts the collar portion, and such that the helical spring is in direct contact with the shoulder portion; wherein the helical spring comprises three strands of wire that are twisted together and wrapped to form the helical spring.
