The J P Enterprises Silent Captured Spring Gen 2, H2 (J P Enterprises part no. JPSCS2-15H2) combines a heavier H2-weight buffer with its captured spring design in a single unit built for standard AR-15 platforms. The added H2 mass slows bolt carrier velocity more than the standard-weight version, which helps tame an over-gassed rifle, a suppressed build, or a shorter-barreled carbine that cycles harder than intended. Like the standard Silent Captured Spring, the H2 version eliminates the buzz and rattle of a traditional separate buffer and spring for quieter, smoother function. It is the right choice for AR-15 owners who need extra buffer weight along with the Silent Captured Spring’s quiet, self-contained design.
