Bore Gauge to check Concentricity - Thanks for the Advice!!

[dreadpirate]

Thanks for recommending a bore gauge to check concentricity (https://www.mdshooters.com/showthread.php?t=213366)

I had a o-ring between the rifle and extension, and that o-ring threw off the centering just a hair - but was noticeable. Much better without it. Better safe than baffle strike!

Yes there's several threads out here that state a suppressor or qd mount for a suppressor should be mounted to the shoulder of the barrel. Never use a crush washer for that reason. If timing is required use peel washers or similar.

Were you able to get a rod down your barrel to check for concentricity?

Yes - but this was not a crush washer - this was a rubber o-ring.

Yes the can, extension, and barrel gauged true.
