Excellent product. Only blem is a small scratch on the best in the qd end sling mount by the castle nut. No massive offer to me and saved $90.

The Mk2 higher receiver moves mass into considerate reinforcement on the front in the receiver, as well as the ejection port particularly. It isn’t visually apparent at a glance, but the moment your still left hand curls throughout the receiver to close the ejection port include, your fingers truly feel a definite variation in the shape and mass around the ejection port alone. Immediately after a long time of closing basically equivalent mil spec ejection port handles, it had been a little bit of a shock to come to feel such a shelf around the port. BCM estimates that there's about 60 p.c additional mass reinforcing the forward end of your receiver. Bravo Company estimates the effect of its redesigned forging is thirty percent extra rigidity. In principle, that rigidity ought to be favorable to precision and also resisting change. I examined a number of masses in the Mk2, taking pictures susceptible with Armageddon Equipment bags supporting equally the front and rear on the rifle. The upper sported a Vortex Razor HD Gen II E one-6x optic. Group immediately after group bracketed only a little bit more than three/four MOA, using a couple getting a fifth shot that stretched out towards 1 inch, and a few that cut near to a 50 % inch.
