Stainless steel buffer designed specifically for pistol caliber conversions with collapsable stocks. The 7 ounce weight and longer length contribute to a shorter stroke and softer felt recoil. The sliding insert acts as an anti bounce weight. The unique shaped polyurethane bumper is designed to absorb energy for softer operation.
When converting a GWACS/Cavarms CAV-15 MKII receiver this buffer is required to prevent damage to the lower receiver.
Will NOT work with rifle caliber uppers.
Will NOT work with full length fixed stocks.

Combined with a New Frontier modular bolt and standard buffer spring it is really smooth in a 4" barreled upper with suppressor. 100% function on registered lower and locked back every time. Nice cyclic rate. You can hear the weights in the buffer if you shake the firearm, but I did not notice the noise when shooting.
