Built 2x 6.5cms and ended up changing my mind on muzzle devices. Going with quick discos for suppressors rather than these muzzle breaks. I have VG6 gammas on most of my AR15s and 10s. One of the best out there!

I paid full price off aero's website months ago, but looks like they are cheaper on a few other sites. So I'll undercut em all and go 50 each, or 100 for both ;) I paid $94.99 each a few months back.

Thanks
