I have hand filed two that needed it, it doesn't take much at all. The vast majority do not require fitting especially if you either chase the threads or repeatedly work the rec on and off the barrel, I believe most of the problem comes from the Parkerizing on the rec. and in the Rec. threads, and mating surface. With a really good barrel vice, rec wrench, and cheater pipe it is usually not a big deal. It is much more problematic if you take off too much, there is no going back.
get it to hand time to 10:30 and your good, I use a 5' cheater bar, tried that yet?There's a reason people split the old rec stubs the factory put them on really tight. Why should yours be any different?
NONE of them got closer than 10 o'clock....
(WITH wrench and vice)
What are ya'll doing to get Reciever to barrel match?
I'm too anal retentive to want to hand file it to fit...
I'll pay for a lath to do it...
I have heard of people marking the shoulder with a sharpie marker, then taking a triangular file with a safe face and filling away the sharpee marks.
Just got my barrel back form being cut for my PARA build, so now its time ot get this party started!!!
