Went back and checked, KevinB nowhere to be found on page 1.
Relax, I'm with you on this one. I don't see how this is any different than the Sabre thread where guys were asking the same sort of questions about what they'd be getting for their hard earned dough. Only difference I see between this and the other is that John at Wolverine answered all the questions asked.
Mil Spec? What the hell does that mean. People throw the term around like it's the end all be all and half the time they don't know what it means. For example when Rick at ATRS started telling us about his lowers he claimed that the 7075 T6 Aluminum he would be using is greater than mil spec. Little did he realize that 7075 had been the mil spec for a couple of decades. Once he was aware he stood corrected and carried on.wwwww
I think that what most people would like to know is how these stack up against "The Chart". Answer that and people can make the decision for themselves.
A chrome bolt carrier group hasn't been in use in the US for the last few decades, while it was the original spec, that's no longer the case. Any unit that still has chromed carrier groups are allowed to retain them for training purposes but they aren't allowed in the sand box. As for the reason behind all that, I don't really know, just saying that it ain't "mil spec".
Oh, and for those that don't get it, 1/9 definitely isn't military twist rate, therefore not part of any "spec". And what of the barrel steel? Is it 4140, 4150, CMV? Does it meet the mil spec" standard set out in MIL-B-11595E for chemical composition?
80% parts interchangeability? Still confused by that one, just looking for some clarification is all.
The point is people have valid questions, why is it so hard to get straight answers?
