(Bufferless Receiver Extension, brand part number 04-06143-32) is a 6-position adjustable carbine buffer tube built to seamlessly integrate with mil-spec AR-15 carbine stocks, finished in flat dark earth. It ships with a folding Picatinny stock adapter that mounts to buffer-less platforms including the Brownells BRN-180, Sig Sauer MCX, and Sig Sauer MPX, and the folding mechanism itself can be removed and reattached for a right-side fold.
