The Samson Manufacturing B.R.E. (Bufferless Receiver Extension), part number 04-06143-01 (black version), is a specialized 6-position adjustable carbine receiver extension designed for bufferless firearm platforms. It allows you to mount standard mil-spec AR-15 adjustable carbine stocks (stock not included) on guns that don't use a traditional buffer tube.
