JP's 9mm 5H2 Silent Captured spring will increase the reliability of your pistol caliber carbine, allow for more weight tuning options and speed up accurate second shots. The extra mass in the free float buffer weights helps the blowback style action operate smoothly and consistently. This effect is known as the "dead blow hammer effect", meaning that the weight transfer is spread out over time, smoothing out the reciprocating mass bottoming out and closing. It will also help to reduce the stroke length of your operating system, especially when used with the JP 9mm bolt. Another great benefit of this product is that it will mitigate the amount of bolt bounce, which in turn leads to a faster firing impulse. Using all tungsten weights, this buffer is quite heavy and works great with suppressed SBRs and pistols.
