You have the most accurate xcr-m on the planet if it can pull 1 moa on average from five round groups.
Show me four or five groups averaging 1moa on the same target sheet and my world will be turned upside down.
It's all been done before.
But to summarize, your looking at 2 to 3 moa at absolute best for an average group size with five round groups.
Vertical stringing due to the Mickey Mouse barrel attachment method is common.
For the fan boys, yes it'll pull a decent group off once in a while, especially if you're a three round group kind of guy. But the average isn't good.
To the op, slap an eotech, aim point etc on there and have fun, it'll never be a precision rifle so you might as well play to its strengths (soft recoil, ergos).
