Surplus Colt 4 Position M4 7075 Forged Carbine Buffer Tube

Surplus 4 position Colt buffer tube

Perfect for Colt and mil-spec builds, when you need Colt. The four position buffer tube is trademark protected, and is made of hardened 7075 aluminum forgings and then cut to exacting standards to hold the weight of the stock and gun in battle. Why settle for something less, when you can have Colt quality where it counts -- in an area that is prone to stress on your AR.
