Ar-15 Silent Captured Springs Gen 2 H2 - Ar-15 Silent Captured Spring Gen 2 H2 W/ Alt Spring Pack

The Gen 2 Drop-in captured-spring recoil system helps your AR function more smoothly and quieter without any permanent modifications. The carefully balanced, custom-ground buffer spring, combined with the JP LMOS buffer, greatly reduces friction and vibration - say goodbye to the annoying “spoon over a cheese grater” noise of conventional springs and buffers. Fits buffer tubes for both M4-style collapsible stocks and also, using the included spacer, the longer tubes for fixed rifle stocks.   The H2 buffer is heavier than the standard spring. The buffer includes two Tungsten weights in addition to one steel weight. Weighing approximately 4.7 oz. Recommended for use Mfg: J P Enterprises
