great lower, one flaw

by -

This comes with BCMs MK2 buffer Mod1 T0 buffer (3oz). As most rifles are running a mid-length gas system, be prepared to spend more for a heavier buffer. Most mid lengths run best on a H2/(T2) buffer



Got this on sale for $370 for my first rifle build. Seems to be excellent quality, very happy with my purchase!

Excellent Product

Great lower for the money. Mine actually came with the H2 buffer. Paired it with a BCM 14.5 upper I found on sale. Ran flawlessly for the Few hundred rounds I’ve shot. Very smooth shooter.

MK2 delivers

And it is BCM reliable.
