I bought a J&T 16" barrel CAR flat top upper and it handles and weighs almost the exact same amount as my 16" 5.56 Bushmaster chrome lined barreled flat top upper. I like the balance of the 16" uppers better than the 14.5" barrels that I've handled. I figured if the barrel/flash hider had to be 16" I'd rather have the longer barrel for more muzzle velocity. I can't have an SBR because of where I live so I opted for the 16 inch barrel. I wanted my 6.5 Grendel to match the handling of my 16" duty rifle. I figure I get from 25 to 50 FPS more velocity out of the 16" barrel compared to 14.5. This is not a lot of velocity difference so I think it boils down to personal preference.
