Product Description
The Luth-AR A2 Rifle Buffer Tube (rifle buttstock extension tube) is a durable, A2-style receiver extension engineered for AR rifle buffer systems. Built from 6061-T6 aluminum and finished in hardcoat anodized black, it is designed to fit both .223/5.56 AR-15 platforms and .308/7.62 AR-10 platforms and pairs with an A2 fixed buttstock (including A2-style stocks such as the Luth-AR MBA-1/MBA-2). Note: installing an A2 rifle buffer system on a carbine may affect function; there is no difference between “.223” and “.308” A2 tubes—this tube is the same for both.
