I second this. I have had a customer bring a gun built on one of these recievers after ~2000 rds. Trigger and hammer pins were both sloppy from rotation. This is the reason even the best aluminum recievers I build on get drilled for stainless bushings for the pins to ride in. I also drill and tap for an adjuster screw to tighten the upper to lower fitup. Not necessary on mil carbine builds, I mostly build high end varmit guns. But nice if you want to take the AR to the next level.
