Okay, got my upper back from RGA today. A complete new unit.
No explanation from Chip as to why they replaced the entire unit. I asked him
via email a couple times, and never got a firm reply. O well, I got a replacement
at least. +1 to LMT for their service.
Took four loaded mags out in the boonies soon I wouldn't piss off any sheeple. Fired
all 4 as fast as I could. NO MALFS. Outside of the barrel had a kind of whiteish appearance
when I was done. I would assume this is normal? Also, hehehe, I didn't take the QC tag
off the FSB (on the odds that I might sell it) and the fucker melted off, and part of it
melted onto the barrel in front of the FSB. I had a bitch of a time getting it off there
once the barrel cooled on the trip home but managed to get it off with no issues.
Didn't have time to test fire for windage zero, so that's up in the air. First one
shot about 3.5-4 inches right @25 yards on mechanical zero windage.
Noted the SAME thing that I noted with upper #1: namely, with a carry handle
mounted, the front edge of the Pic rail does not look flat, it looks slightly concave.
Its VERY slight but I can see it. Why can't they machine a flat rail? The rail
on my BM is FLAT at the point. Is that
going to affect anything if I mount optics on that area of the rail?
Hrm.....at least it ran like a raped ape, and that was with a BM bolt group. If
I decide to keep it, I'm going to get a Colt M16 group and throw it in there. Funds
are kinda tight right now thou. If it zero's okay, I may very well keep it. Still
tempted to get a 6920 thou. Finish is pretty damn good, but to be honest
I don't really give a shit about that, as long as it runs good. A nice finish
isn't going to save your life, or your family's.
Just for reference I did the mag dumps with XM193.
