DB Alloy 5.7, MPA upper, SCS for the plates, random obnoxious brake that was in the bin, $25 river store dot, wifes fingernail polish to color code the safe/fire indicator dimples, and motorcycle engine anti-walk.

Is there anywhere other than mpa selling the uppers in 5.7?
I haven't seen any others offered in 5.7. The MPA upper is pretty decent, no complaints. You do have to trim a little bit out of the rear section for FCG clearance, but it's not bad at all.
My only gripe is the stock situation. I think it speaks to the size of 3d2a community. Impact 5.7 uppers being out of stock at the same time of unseenkillers 5.7 Mac release may be coincidence but I somehow don't think I'm it is having seen similar things being suddenly in out of stock shortly after a 3d2a release more than once in my two year span of interest in the hobby segment.
Yeah, when it first came out, I waited a couple months before it came back in stock. It may show that 3d2a is more popular than it used to be, and companies popping up aimed entirely at that market segment proves it. Ultimately it's still going to be a niche low-volume product, so they'll do it in smaller batches and get back to regular bread and butter production. Happy to see them doing it at all.
