The MagnetoSpeed V3 ballistic chronograph kit is designed for use on any suppressor or barrel from ½-2 inches in diameter.  The V3 has one full inch more in clearance to account for longer muzzle brakes, flash hiders, ect.  The Bayonet sensor straps onto the end of your rifle barrel using electromagnetic sensors to detect your bullet speed rather than light sensors.  This takes away all the worry that florescent lights, strong sun, and low light bring to measuring the speed of you bullet.  In ANY conditions the V3 will function properly.
