Some rifles with 1/2 X 28 thread pitch have the threads .600 inch deep. Most rimfire rifles and suppressors are only threaded .400 inch deep.

You can get a spacer that threads on and keeps your suppressor in line so you don't get baffle strikes.

I have one that I have to use on a couple rifles.

If you like the way it shoots, a spacer is a lot cheaper than a new barrel. Now if you want a new barrel for other reasons, I won't talk you out of it.
There’s a taper, almost like pipe thread, and virtually no thread relief…a spacer won’t screw all the way down to the shoulder of the barrel.

If you turn out some of the spacers thread, it will screw down flush
The problem is ‘deeply rooted’ in that there’s no relief, the treads are terrible, AND there aren’t enough of them to space and have enough left to screw a can on….basically ruined the f’n barrel to my notion.

In my over 50 years of fooling with this stuff I’ve never seen anything quite like it….why?

The guy I got this from either lied through his teeth or is a complete idiot….I’m thinking both counts. It’s got a 10oz Jewell but the stock was never inlet for it to move in an arc and he said it must have some grit in it?!

I may take the stripped down action to a ‘smith that would be able to spin it and cut a relief behind the existing threads, re-cut/chase them, then fit a proper spacer and red LocTite it in place….or get it re-barreled.

I’d have a threaded 18” heavy barrel if I had my druthers…
