Just wanted to share this.

I installed the Nordic Tactical Compensator on my AR upper, permanently pinned and welded. I went with this comp becuase the OD is less than 0.750, and the FSB (or gas block) will clear it. I was able to remove my FSB and install my Spikes SAR rail, without having to remove the comp. Others out there are larger in diameter, which means you have to remove the device if you want to change your upper up. Its worth considering if you like to like to tinker, but have to play by NJ rules.....

I'll get some pics up tonight.

Yep, Raz-0 and I both have been recommending for NJ silliness. They are not the BEST comp out there, there are more effective ones, but if you want to build a gun you want to take apart often then they are quite nice.

OD is less then .750? or it is .750? Not a big fan of the way it looks flush, so i would probably hate a reverse step comp. Definitely helps if you plan on changing things up.

less than 0.750" but not by much... mine mic'ed at 0.743"
