MagnetoSpeed

The MagnetoSpeed barrel-mounted, ballistic chronograph has brought modern convenience to the often tiresome task of measuring bullet velocities. The MagnetoSpeeed chronographs use ground breaking electromagnetic sensors, instead of problematic optical sensors, to eliminate common chronograph problems. Magnetospeed chronographs are swift to set up, accurate, impervious to light conditions, do not blow over in high winds and easily fit in a range bag.

The MagnetoSpeed RifleKuhl Barrel Cooler is designed to cool your barrel down faster, so you don't have to wait. It is powered by a CR123A Lithium battery (included) that pushes filtered air down your barrel to cool it at a faster rate. The MagnetoSpeed RifleKuhl Barrel Cooler pushes air through the bore of the barrel at a rate that will typically cool the barrel in under 7 minutes. Riflekuhl doubles as a chamber flag and features an exclusive built-in air filter to prevent dust and dirt from being blown into your rifle.
