Thanks Buds again for...
Thanks Buds again for the fast shipment. I have other products from CMMG and never had any issues before, but they really dropped the ball on this one and I am very disappointed with CMMG quality control. When I picked up the gun, I noticed that the grip was a little loose, but thought this was not big deal, I can just tighten the grip screw when I get home. Turns out that the pistol grip screw hole was not properly done/threaded at the factory and the grip screw will not go all the way in. As a result I have a bad receiver, with a loose grip, and it will need gunsmith work.
