Now at Aim Surplus, should be available at Brownells any day now too! I got to play with this some in the beta phase and must say it rocks and is just what RS Regulate does, a solid, simple upgrade that works. Just like the AK platform! I'll be getting one for review and if as good as the beta version, I already anticipated it being a permanent part of my gear on standard barrel diameter AKs. My busy part of the year is kind of winding down and I will have more time to post reviews, like on it and some other products I have waiting to be given some range attention.
