Barrel movement ar-15

[Blue Diamond]

So me tightening it to 50ft lbs and it having no play still isnt right?

If u tightened it to 50 f/p and your gas tube lines up then you are great. I have seen some up to 100+ f/p. The problem lies with the teeth of the barrel nut. I have tightened some and the tooth was just a wee bit past the gas tube passage and it means you have to go to the next tooth or try a shim.

No that is not what I said at all,,mr know it all.What parish are you in,?
I just want to make sure no one calls on you for fixing anything or actually
knowing laws.Get over yourself man...Until you have had actual experience
doing what some one is asking,then by all means speak up,if not shut your
google fu the &^*&&^^& down ...

I simply stated when it comes to putting ar15s together,there is no
one perfect spec,everyone of them are different.

Different lowers,different uppers,,diff companies making many different
parts.And please do not use shims,if you need shims on an ar15,you
have done something wrong or about to.

I trust very few real gunsmiths for this very reason.I have seen some
pretty messed up stuff.If you cant figure out the problem on your own,
with youtube videos and 1000s of other videos,then I'm betting you
should not be on that end of the project

Good luck and I hope you find a decent gunsmith.I know very few good
ones.

I have experience in this matter. So if I were to follow your rules, you approve of my speaking up.

And you didn't simply state there was no perfect spec. Your first line was "what does that even mean."
