This is an MCX LT upper that will fit on any MIL-SPEC AR lower and turn your boring AR into a kick-ass MCX LT. This upper will include the buffer tube extension delete which will allow you to attach any folding stock of your choice. The MCX upper is a piston driven system with two gas setting, the barrels are interchangeable with other calibers and feature m-lok in 3 6 9 positions. This upper has seen no more than 500 rounds so it is basically brand new.
