Another loose barrel found.

ordered a wrench myself from tacticool as i feel i might have the same problem. I noticed on lmy last range trip that the groups opened up. I would get some nice tight groups then a few fliers. then a nice tight group but off (zerod scope again) and the same pattern of tight flyers then tight but off center.Was wondering how tight should the barrel be? I don't want to over tighten it.

I don't use a torque wrench but just tighten using 2 fingers. As you said, you don't want to over tighten.

IMO, if you tighten so much that you need to put a wrench on the end of the barrel nut tool to get it loose again, then you've gone too far. I can firmly grab the end of the wrench with my hand to loosen my barrel nut. That may seem too loose for some but I've never had the barrel nut back off any after prolonged shooting.
 
So someone jumped in my post about a new barrel. Saying S&W needs to do it for headspace.

How can everyone take their barrel out if the guy is right in my thread? :rolleyes:

Question is, is that guy correct? All kinds of info online... some correct, some wrong. Guess you need to figure out who is correct.:)
 
I'm not here to say anyone is wrong. Just know ARs & 15-22s are made to be user disassembled. My barrel has been swapped out, removed for cleaning & removed for getting cut down... all told multiple times. I've never heard of headspace issues when putting these barrels back on.
 
I just hand tighten mine.... no vice.

A bit of historical trivia---

Before Shooboy and Tacticool22 were offering proper steel wrenches, we were using PVC and cutting out the fingers to fit in the barrel nut. A bit crude, but necessity is the mother of invention, right:D? Anyway... I think most folks found that the barrel nut isn't torqued too much from the factory whatever spec (if there is a spec) might be.
 
The closest thing I have gotten for a "factory spec" is 20 foot pounds.

Head space is determined by the cutout in the bolt for rim fire.
