Well it looks like my 6.5 Grendel upper I got to replace the side charging AR10 upper that was a POS is about the same.

It won't consistenly go into battery. Even if I hand cycle it. Changed mags and ammo. Still a no go. Their stupid online customer service email won't generate a captcha so I can submit a question.

I really don't get it. I have a 223 Wylde and a 450 BM from them, and they are flawless.

From what little I could get the stupid thing to shoot, it looked like it would do some pretty decent groups. This thing has a billet upper too. Anyone got a grendel barrel laying around?

So freaking frustrating. Go to the range, and gun acts up.

And on top of that, I have 2 zeiss scopes on different guns I also shot, and wouldn't you know they adjust totally opposite.............

But hey the 10mm XDM was fun!
