I might want to feature them more.
I remember being absolutely intimidated by the upper on an AR. Must be some fancy precise fitment to get the barrel off. Then I saw it done in front of me and... That's it?
That's so easy!
It's just a matter of seeing it once.
"Yeah, I did all that T-Bolt, changing our a 24 inch heavy barrel for something a bit shorter and now my gun won't cycle! Not so easy."
You know, I haven't a lot of experience building lots of ARs, but I seem to remember there being a relation between barrel length and hence buffer tube length, buffer spring strength, and that little hole in the gasblock/barrel. I'd do a lotta googling to find that out if I were in your shoes.
Oh, some solutions... Save 'enlarging the hole' for last if something else is available first. And those pigtail gas tubes that try to give you a longer tube for a short length... the gunsmith reports less luck with those. Springs an buffer tubes first. Oh, and be sure the hole isn't blocked by a misaligned tube. Super important.
Just stuff to think about. If I was a subject matter expert I'd tell you what fer. But I am not, and can tell you just some places to look. Maybe get you started.
