This is a 5 – position collapsible stock for an AR15 rifle. Works with any existing Mil-Spec Bolt Carrier allowing use with both gas impingement and gas piston systems. Requires only one-handed operation and will lock in the closed, intermediate and extended positions. Supplied with Springs and buffer.
H1 Buffer is standard size buffer (3.9 oz)
H0 Buffer is 3.1 oz
H2 Buffer is 4.6 oz

PWS MK1 MOD1 uppers, rifles and pistols produced from 01-01-13 to 12-31-15 were equipped with a carrier with added mass in the tail that requires our PWS specific smaller diameter buffer for the ARC Stocks.
For all PWS MK1 MOD2 uppers and firearms, the carrier has the standard carrier tail bore dimensions and is compatible with our standard diameter buffers
