This Chester County Armory listing is for an original, Colt factory production eight position rifle length buffer tube, originally made for the Colt ACR (Advanced Combat Rifle).

The ACR was Colt’s entry into the Department of Defense’s ACR program in the 1980’s. Based off the M16A2, it was designed to fire Olin Corporation’s new (at the time) joint collaboration 5.56mm duplex round, as well as standard 5.56mm NATO loadings. Unfortunately for Colt, the DoD ultimately decided against their offering, as there wasn’t a large enough advantage to dismiss the venerable M16 in order to make way for the ACR.

This buffer tube will also work on all mil-spec AR15 and M16 receivers.
