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 13):
A buffer and spring kit for a firearm comprising:\n (a) a buffer including a buffer housing defining a sleeve portion, a collar portion, and a shoulder portion, the shoulder portion having a first outside diameter and 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 configured for mounting to the buffer such that sleeve portion and shoulder portion can extend within an interior space defined by the helical spring with the first end abutting the collar portion and with the helical spring being in direct contact with the shoulder portion; wherein the helical spring includes between  20  and  40  active coils and a free length of between 8.5 and 12.5 inches; and wherein the helical spring is formed from a first wire, a second wire, and a third wire that are braided together to form a stranded wire, wherein each of the first, second and third wires is a steel wire having a diameter of between 0.042 and 0.052 inch.
