Help with A2 Flash Hider Install

[Blitzen]

I want to mount an A2 Flash Hider on my Ar15 barrel (16") that came with a thread protector only. First the A2 clocks pretty much dead on without using a crush washer or shim etc. However once the A2 bottoms out against the barrel face behind the threaded section it only rotates slightly when tightening with a wrench. But once tightened it cannot be removed by hand, have to put the wrench back on it to get it off. Question since it clocks well without washer/shim would it work to install without them and apply a little rocksett or blue Loctite? Have the JP double crush washer and a set of shims for the job. I don't want it to be difficult to remove down the road but also don't want it backing off. Could try it a see how it works. Thanks in advance for any input.

You might be overthinking this.  Crush washer then flash hider.  Screw it on until clocked and no more.  No loctite whatsover!

What he said.

Thanks. I overthink things often. With crush washer will need approx 270 degree rotation to get it clocked.

The great thing about a crush washer is you can file it thinner to fit the need.

I am thinking that a crush washer is not needed as long as the hider is clocked correctly.

I have installed 2 of the Kaw Valley Comps that come with the instructions to not use a crush washer-as to they are not a necessity.
