Managed to get in a range session just before they shut her down for the fire hazard here.
First the negative:
1. It did not like 62gr 5.56mm NATO. The action would seize after firing and had to be mortared or both slide and cocking bolt pulled simultaneously very hard, to extract 32 of 35rds fired.
2. Not awesome accuracy. One 2" group but mostly 3" with a few 4".
3. Had to chase the zero a bit. Not very consistent.
Before you speculate, I have a wall of plaques etc to prove it wasn't me and the scope is a 16x I have used reliably for years that was mounted via a PEPR mount. It was shot on a Harris bipod and the butt sandbagged. Had I remembered to bring more sandbags I could have expected better results from bags only.
The good:
1. With 55gr 223 the gun ran well without any hard extraction. Did not get to check accuracy with it.
2. The BCL MRX 20rd mags only needed about 1/8" removed from the back spine. Once done they worked flawless.
Conclusion. I think for now this would be a good rifle for 3 gun or short range tactical matches. Because I have a quantity of 5.56, It is clearly not the 5.56 rifle I needed but if running 223 you will be fine. Keep in mind that this was only my experience and perhaps not indicative of how other rifles will perform.
