I figured. It gave up about 300 fps incidentally. The AR10t has a 24" barrel which actually gives it substantially more muzzle velocity than most AR10s that typically come with 20" barrels (or shorter). I would anticipate shooting at less than 500 yards most all of the time with this rifle (and less than 300 more often than not). The decreased MV shouldn't be a huge issue inside 500 meters. The compact nature of the rifle makes it better suited for CQB type scenarios as well.
if you can only grab one rifle-it has to versatile.
