It's an interesting design, but the Surefire shims are free. Plus I know they, along with the chamfered spacer, keep the muzzle device square for the suppressor.

I'm just impressed with how much shorter SF was able to make something and it still be compatible. I'm guessing there will be more blow back on the barrel, but that's not really a big deal.
