How CRUSHED does a crush washer need to be?

Hey guys-I've only ever installed one muzzle device, and it was a long time ago on a far more robustly-built gun. Looking at linear compensators for my 457 Scout, which is a tiny barreled action. I assume you guys installing these types of things use a vise of some kind, wooden blocks etc.? Might be DLASK, might be one of these handsome fellas;

From my experience, once the muzzle device engages the crush washer, you have about 360 degrees to adjust or "time" it?. I personally wouldn't go past that 360 once engaged, but it may vary from device to device and how much thread space you have? Holding the barrel in a padded vise when installing any muzzle device is a wise decision IMO.

The point of a crush-washer is more to apply proper/constant tension between devices to hold alignment, not how well/much it crushes.
 
If you're muzzle device needs to be 'timed', you can either use a crush washer (which is really a constant torque washer) or shims. A standard 'crush washer' as typically used on ARs etc. for muzzle devices, typically allows for 1 to 1.5 full rotations of 'crush'.
 
Just remember to clamp the barrel in a vice so you don't induce torque on the receiver. I've seen bad things happen if the barrel isn't supported.

Thanks for the input everyone, and for confirming. I made barrel "blocks" when I did this the first time, I'll have to confirm they'll work on such a small barrel. May have to make different ones. lol

Safe shooting
 
Another option might be to use a spark plug washer instead of a true crush washer if it is only being used on a rimfire as it will probably be easier to index and won't take as much muscle to turn. I'd only trust this on a rimfire because I've seen centerfire rifles unscrew muzzle brakes, but this mostly happens when they are radialy ported.
 
For what it's worth, if the linear compensator does not to be oriented in certain position, I was told that for a 22lr it is OK to just tie it by hand.
I did just that and never had an issue.

Yep. Linear comps I don't use any tools, just a drop of blue loctite and tighten by hand.
