BEST ANSWER: It has a shockwave pistol brace, so it is classified as a pistol. As far as needing a conceal carry permit to keep it on you in a bag or in your car, it would depend on your local laws.
What is the inside diameter (ID) of this handguard? Wanting to see if my can will fit or if I have to get the 8" version. ~thx

BEST ANSWER: The outside diameter (OD) of the flash can is 1 3/16" (2.9 cm or between 2.9 and 3 cm). I would say there's a 1/32" gap between the inside diameter (ID) of the handguard and the OD of the flash can.

Quality great price. Just buy it. You won’t regret it.
This thing is awesome! The quality is there and i like the changes made from the older gen ar9 platforms. The Rail is perfect length and the muzzle device direct the blast away. this thing shoots like a dream so far. Right out of the box 250 rounds no problems. Quality for sure and a great price for the brace extra mag and moe grip. I’d buy another for sure.
