Thread: supressor sitting inside handgaurd

Hey guys,

Just asking a question here, and would like opinions from experience would be beneficial.

But, in theory, if a hand gaurd/ forend with 39mm internal diameter was to have a supressor that's 38mm diameter inside of it, would this be a bad move? Would barrell harmonics cause problems etc ?

What would be the minimum clearance between a supressor and a handgaurd?

Cheers

I had this on a blackout. Smoke the inside front edge of the hand guard with a burning match, spin on the can with white masking tape around the bit that lines up with the smoked area. Shoot it or bang the hand guard with your hand a few times. If you get carbon transferred to the tape, you’re not golden.

I guess it depends on what barrel thickness/length/calibre you have, and how much it 'whips' when fired. Very close tolerances are always a good thing in firearms, except where things that aren't supposed to touch end up in contact. I'd say that 1mm is too close for comfort on most rifles.

It's a bartlein barrel, super heavy profile.

1mm may be enough if the barrel is super rigid, but I'd hate to test that and get it wrong. What caliber is it?

6 5prc. If it's too dodgy of a risk, I'll just make it close to flush with the end.

any chance you could remove the forend and get it turned up in a lathe. Take another mm off the inside for a short distance and then fit your suppressor. A suppressor tucked neatly inside the hand guard makes for a very tidy unit.

That was pretty much the plan mate. Yeah, I know a few people with lathes, and I'm sure I can get a lil more clearance. In a super heavy profile barrell would would the minimum clearance be ?
