I have almost 600 through mine. But because of back lash, I won't post another range report. The last time I did, it got locked from the trolls. It was quite a long one too. Sorry.
I have about 500 rounds through mine and love it. The gun thrives on 69 gr SMKs and Varget.
I read your review and agreed with it, but declined to post anything after seeing you get torn to shreds by the haters and ass h0les that seem to have a problem with high quality or ATRS. I know of several other MH or MV owners in the same boat, but who needs the drama?
A shame really, but like with all things, a few screw it up for the majority.
