Congrats on the new purchase! Everywhere I looked says even 11.5" barrel pistol ARs are still under 26" oal measured end of threads to end of mil spec tube.

--edit I'll have to get one eventually and measure for myself.

I hope you have a .30 can. You should order one if you don't, and one of those arm brace things that aren't a stock.

FYI: My 10.5" 5.56 AR is 26.5" INCLUDING a 2" muzzle device.
Without the muzzle device it'd probably be around 25".
