Built around a \u003cstrong\u003e6-position, 7.8\" hard-coat anodized 6061-T6 aluminum tube\u003c\/strong\u003e with a \u003cstrong\u003eslanted back\u003c\/strong\u003e profile, this assembly is a direct fit for AR-15 lowers cut for the commercial buffer tube standard.\u003c\/span\u003e\u003c\/p\u003e\\n\\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eTube and thread dimensions are \u003cstrong\u003ecommercial-spec at approximately 1.17\" diameter\u003c\/strong\u003e, which matters when pairing this tube with a buttstock and castle nut: commercial and mil-spec buffer tubes are not interchangeable with the same furniture. If you are building or rebuilding an AR-15, confirm the standard of your lower and your intended stock before purchase. The \u003cstrong\u003eblack hard-coat anodized\u003c\/strong\u003e finish provides corrosion and wear resistance and matches typical AR-15 lower receiver aesthetics.\u003c\/span\u003e\u003c\/p\u003e\\n\\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe A5101050 keeps installed weight low while delivering the strength needed for the buffer and spring to cycle reliably under sustained fire, and the 6-position layout lets the shooter dial in length of pull to suit body armor, shooting position, or loadout.
