And here is the weak link IMO. This piece that keeps the charging handle captured should probably be steel. If it gets bent or broken you are seriously up a creek.
I found charging the firearm to be FAAAR easier. This platform has always been a pain in the ass to charge. And doing drill with it.... you had to have a pretty good grip.
I intend to get a LaRue QD mount for my Nikon 5.5-16.5x44. I want to see just how well I can shoot.
I took it out yesterday, and I quickly realized why the Army made you wear glasses. My vision isn't atrocious, but I couldn't see the white circle in the orange square at 50yds. Maybe those orange stickies would be better... but glasses would be the right thing.
I did manage to keep it in a 3" group at 50yds, and I barely needed any adjustment, 2 clicks left.
Now I need to get glasses. I started shooting better, but still just too fuzzy to be accurate. And wasting ammo at that.
