Welp, went ahead and took the rifle out today. The truglo holographic red dot was a let-down; after only 15 rounds downrange the reticle started to flicker in/out as if the battery was making inconsistent contact
. Well, at least it maintained it's zero, right? It did provide enough adjustment to line up correctly even with the BP02 mount skewed by a couple of degrees.
The rifle performed well; no issues at all with functionality in about 250 rounds fired. The iron sights were off about 4 feet high at 20 yards, so it took some adjustment to bring it on target, but windage is dead on.
The only negative that I found was the receiver cover gets pushed back, out of the groove above the chamber when the rifle is fired. After 200 rounds, the receiver cover had actually popped out of the groove and jammed against the bottom of the iron sights. When I attach the cover, I can push it forward all the way into the groove, but just by pulling the bolt handle all the way back to charge the weapon, the cover is pushed back to almost the point where it pops out of the groove.
I'll take it out again this weekend and see if it's a chronic problem; has anyone else seen anything like this happen before? It's like the slide cover is 2-3mm too short or something.
