kilovector,

Earlier this year we introduced the "BA" (brake attach) versions of the 30P-1 and 338P-1. We haven't found a "quick attach" mount that meets our standards for accuracy and repeatability (we make precision/LR cans primarily after all) -- the BA does -- so we went with that direction for the users that need a muzzle device when the can comes off. No mount is really "QD" once you get it to 800 degrees unless you have some welding gloves handy.
