Comparison J P Enterprises 308 Ar Captured Springs Gen 2 H2
Weighing approximately 4.7 oz. The H2 buffer is heavier than the standard spring. 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. The Gen 2 Drop-in captured-spring recoil system helps your AR function more smoothly and quieter without any permanent modifications. Recommended for use Mfg: J P Enterprises. Fits buffer tubes for both M4-style collapsible stocks and also, using the included spacer, the longer tubes for fixed rifle stocks. The buffer includes two Tungsten weights in addition to one steel weight.
