Flat music wire buffer spring delivers 7% more compression tension than a factory-spec spring for a longer operating lifespan, more reliable cycling, and elimination of the “raspy” noise during cycling. After extensive testing, the folks at JP concluded that the extra power produces a faster, more controllable recoil impulse and enables the weapon to press fully into battery with even with a lot of fouling present. Outer-diameter is ground and polished for smooth, quiet movement in the buffer tube. Rifle fits fixed stock rifles with A1/A2 buffer tube. Carbine fits collapsible M4-type carbine-length buffer tube. 308 Rifle – Fits AR10 and 308 AR fixed stock rifles with an A1/A2 buffer tube. 308 Carbine – fits AR10 and 308 AR carbine buffer tubes.
