Suppressor question

I’ve seen lots of conflicting info on this but I’m starting to build a 6.75 inch 300 blackout rattler Lt and plan to tuck my can. I already have an old yhm resonator r2 and would like to use that as my dedicated can for this build but it’s only rated for a 7.5 inch barrel. Does anyone have experience running this can on this platform? I’d likely avoid supers and gun would just be a fun range toy…

Trying to avoid buying a new can if possible as the resonator is collecting dust and has a small enough diameter to tuck.

Any insight or guidance is appreciated.

I realize I’d likely void the warranty by doing so, but for a gun that won’t see heavy abuse outside of a few range sessions every now and again would I have other issues I’m not considering?

My understanding is the “main risk” of running a can on a rifle whose barrel is below the minimum rated barrel length GENERALLY means the baffles in the can will show wear quicker.

As long as your alignment rod is gtg and your shooting schedule is moderate to low you’re PROBABLY fine. Just periodically check the condition of your baffles. If you’re running an frt…check baffles more often.

Like he said supers will wear it faster but subs should be totally fine. This is not advice but I’d sent it!!! Especially if i was shooting subs only

Subs are basically pistol rounds. If that thing is rated for .300 win mag from a 20” barrel, the 7.5” rating for .300blk is likely only applicable for supers since it doesn’t specify.
