Bench Report: CMMG Upper Free Float Tube

I decided to put the Troy Alpha Rail on the CMMG 22LR upper instead of returning it. The upper should be a little bit more accurate now. I will have to test off the benchrest to see.

  1. I haven't filmed it at the range since doing this and only had it the range once … accuracy tightened up … I'll try to duplicate, but at 100 yards, was able to shoot right around 1 MOA with Winchester 555 bulk pack ammo.

  2. I also had to get a Higher scope ring mount with my Rail, I use a 9×16 44 scope and had to completely remove the rear sight. I keep the front iron sight on it for when I swap my scope out and put on my red dot. Plus, it looks better.
