Timing problem with Surefire compensator

[grayfox]

I think that 24-set washer pack A5 is talking about is Accuwasher... each washer is slightly thicker/thinner and they are marked with little hashes to tell them apart, follow their instructions and you're timed in about 5-10 minutes, I'd still use some loktite, blue, or red if you're gonna do rapid fire strings. I've also used the lock washer style, you can use some shims as space-fillers if you want but not necessary... A 6 or 8 set of 5/8x24 is maybe 10 bucks on Amazon etc. Also really easy, 5-10 minutes if you're slow. Loktite again.
