my first AR buid question.....12" 6.5 grendel

[CS1983]

Not for pistol.

But be aware that pistols probably can’t wear braces under hunting regs.

Correct, at least as I read it.

Pg 14 of the current regs:

7. HANDGUNS
a. Barrel must be a minimum of 4 inches long.
b. Must use a minimum .24-caliber (6 mm) in diameter expanding bullet.
c. Shoulder stocks or attachments prohibited.
d. Must use a cartridge or load that produces minimum energy of 550-ft.-pounds at 50 yards as rated by manufacturer

Rifles:

142020 COLORADO BIG GAME HUNTING: HUNTING LAWSHUNTING LAWS
1. CENTERFIRE RIFLES
a. Must be a minimum of .24 caliber (6 mm).
b. Must have a minimum 16-inch barrel and be at least 26 inches long.
c. If semiautomatic, a maximum of six rounds are allowed in the magazine and chamber combined.
d. Must use expanding bullets that weigh a minimum of 70 grains for deer, pronghorn and bear, 85 grains for elk and moose, and have an impact energy (at 100 yards) of 1,000 ft.-pounds as rated by manufacturer.
e. It is illegal to hunt game birds, small-game mammals or furbearers with a centerfire rifle larger than .23 caliber during regular rifle deer and elk seasons west of I-25, without an unfilled deer or elk license for the season. A small-game, furbearer or unfilled big-game license is required.
NOTE: SMART RIFLES are prohibited, including any firearm equipped with a tar-get tracking system, electronically controlled, assisted or computer-linked trigger or a ballistics computer. Any firearm equipped with a scope containing a computer processor is considered to be a smart rifle.
NOTE: FULLY AUTOMATIC RIFLES are prohibited.

So the question becomes if CPW would consider such a thing a pistol or rifle. This would seem common sense and be considered a pistol, since it legally is, but I'd still clarify.

Personally, I dunno that I'd bother trying to hunt with it. Get enough of a dickhead wildlife officer and he might even consider a foam bumper on the pistol tube to be an "attachment".
