Preban Colt 20" Match HBAR 98% condition. Has all the right features to make an M4. Small front pivot and raised mag fence. It has the small single sided sear block. It is also drilled for the push pin from the factory. Barrel is marked CMP 5.56 NATO 1/7. The only thing that keeps the rifle form 99% is that when the screw front pivot was assembled it made a small mark on the flat of the lower pivot and one small scratch just below the sear block on the right side. I am asking 1550.00+ shipping OBO
