Wondering if anyone can measure how deep the threaded section is on their 22 barrel. I don't see it listed on any of the spec sheets I have found on a quick search. I am going to thread one for the 10-22 and am wondering how far down to thread it. I would love to have a measurement. Thanks
 
you're threading it for a brake or suppressor? i'd ask the brake or can manufacturer for their specs. i did that for a brake i put on one of my hunting rifles.

here's what i got back from dead air for their can i put on my cz452 .22lr:
Your suppressor (Dead Air Mask) is intended to be attached to the muzzle end of your firearm. Your suppressor will thread directly onto your existing ½-28 threads. The Mask will attach to threads up to .6 inches long, although a .4 inch long thread is optimal for sound performance and improved baffle life.
 
Barrel thread depth is all over the map. CZ wants .455" Military M16 is .625" some AM's are from .400" and up. They need to get it together.
 
Also it’s a ( I think ) class 3 thread recommended by manufacturers , need to see what the manufacture of your specific item/items recommends
 
.400 is rimfire standard. Unofficial. Comes on Ruger and Savage rimfire, most all 10/22 aftermarket barrels. Only difference would be if running a can needing o-ring engagement.

Something along these lines... I know my savage threads on the SpectreII just fine while my S&W 15-22 needed a spacer - those are pretty readily available.
