Thread: Overbarrel Suppressor Rear Bush fit

So a few questions for the experts (and any others!)
How tight a fit should the rear bush be? Is it just a locator to help keep the suppressor
centred and keep undue sideways pressure off the main thread? Would a tight rear bush
(keep it clean please!) have an effect on barrel whip and therefore accuracy?

Thanks.

Have a quick flick through last weeks threads I'm sure this was literally dealt with then

i cant get mine over the thread seat on my ar barrel so just left it off for now not sure if that's a bad thing, was still impressed with the suppression, mines a dpt. sorry didn't answer your question but i'm interested also

was it this thread?

Does tend to tell me that using a chainsaw file's marginal but doesn't answer my questions :-)
turner nz - mine are DPT as well.

That's the one I was thinking of . . .

I would think that you could happily fire an overbarrel without the bushing.
when I have drilled ones out I go for a diameter a smidgen larger than the barrel so it is a touch fit with it's job being to locate the suppressor.
I tight fit could affect the harmonics of a barrel.

Hopefully DPT will appear and give his thoughts.
