The J P Enterprises Silent Captured Spring Gen 2 (J P Enterprises part no. JPSCS2-10) combines the buffer weight and spring into a single captured unit built specifically for .308-pattern AR-10 rifles. J P Enterprises scales the Gen 2 design up to handle the larger buffer tube and heavier reciprocating mass of a .308 AR-10, eliminating the spring buzz and rattle common with a traditional separate buffer and spring. The self-contained assembly keeps components properly aligned inside the buffer tube, simplifying installation compared to sourcing a matched buffer and spring separately. It is a genuine performance upgrade for .308 AR-10 owners who want quieter, smoother cycling, particularly valuable on suppressed builds.
