Suppressors Can mounts and jam nuts

[sam4886]

What's the consensus on jam nuts for suppressor mounts? I know crush washers and peel washers are generally not recommended, but god do I hate shims.

Most of my brakes are timed with jam nuts from JP, and I'm changing them all over to key-mo for a nomad I have incoming.

Is it OK to time my new muzzle brakes/key-mo mounts with jam nuts? I'll be rocksetting too....

NO

Also, peel washers work fine if they are installed right.

Hmm. Bummer. Shims it is , I guess.

What’s the big deal with shims? Super easy to use.

I find jam nuts to be easier. Besides, shims are ugly. No worries though.

Who is that makes the "precision" shims or whatever? The ones coming with my brakes aren't the greatest.

What cans? Look into the 419 system if it will work with them. 100 something for an adaptor per can and 40 bucks for a barrel adapter piece. Removes shims from the equation altogether.

I’ve found shims from down range products to be okay. Can get them black and stainless and different diameters to match barrels.
