Are these other lowers marked multi-cal and are they the Gen 2 with the adjustment screw on the bottom?
I learned via experience many moons ago that play between upper and lower doesn't matter at all from zero to 300 meters.
I’m an engineer. To save us both time, let’s just assume I’m not wrong.

I wanted to get a demon tactical quick pin for the rear pin on my 24" rifle, but they stopped making he damned things at some point. Cant seem to find a why, but i like the concept of the pin center bushing pushing down on the inside of the pin hole in the upper rather than the set screw or accu wedge that pushes the upper up and away from the lower. Of course, if you are running suppressed that might give you some extra ventilation for those swye gasses... what the fuck do i know...
