J P Enterprises Tuned and Polished Buffer Spring, .308 Rifle-Length

The J P Enterprises Tuned and Polished Buffer Spring (J P Enterprises part no. JPS-OSR.308) is a rifle-length spring built for .308-pattern AR-10 rifles, hand-tuned and polished to reduce friction and buzz compared to a stock buffer spring. J P Enterprises builds its springs to more consistent coil spacing and tension than typical factory-production springs, which translates to smoother cycling and less vibration transferred back to the shooter. A properly tuned spring matters for precision .308 AR shooters who want a stable sight picture through recoil and a soft-shooting rifle. It is a genuine performance upgrade for rifle-length .308 AR-10 owners chasing smoother, more consistent function.
