J P Enterprises Tuned Buffer Spring, Carbine-Length

The J P Enterprises Tuned Buffer Spring (J P Enterprises part no. JPS-OSC) is a carbine-length spring built for standard AR-15 platforms, hand-tuned to more consistent coil spacing and tension than a typical factory-production spring. That extra consistency reduces friction and buzz in the buffer system, giving smoother cycling and a more settled sight picture through recoil. A tuned spring is a simple, low-cost upgrade that many AR-15 builders add alongside a quality buffer for a more refined-feeling rifle. It is a genuine performance part for carbine-length AR-15 owners who want smoother function without a full internals overhaul.
