The Effects Of Reducing The Barrel Length On Velocity And Accuracy In The 223 Remington

All you have to do is extrapolate. The rifle is a Sako S 491 rifle with a 22-inch barrel (to begin with). The barrel went down, one inch at a time, to 10 inches. Chronoed with MANY handloads using 52gr bullets.
Note that a CAR is GAS operated and thus it loses velocity from the gas system to, something a bolt rifle does not.
22 inch 3336 fps, 11 inch, 2842 fps. That's the BEST a 11 inch bolt rifle could get. Just guess what a gas CAR would get! I sure would not be a higher velocity!
It looks like a CAR will lose almost 500 fps over a 22 inch barrel (and the AR-15 is a 20 incher, NOT a 22 incher.)
The CAR is a losers gun, and that's a fact.
