The MagnetoSpeed V3 chronograph barrel mount is a precision shooting accessory built to deliver accurate velocity data from your rifle, shotgun, or air gun without the setup hassle of traditional skyscreen chronographs. Whether you're developing handloads, testing factory ammunition, or validating ballistic predictions for long-range hunting, this barrel-mounted system clamps directly to your muzzle and logs every shot—giving you the real-world numbers you need to dial in your rifle or validate your load data.

Designed to handle modern rifle setups, the V3 accommodates barrel and suppressor diameters from 1/2 inch up to 2 inches, with an additional inch of clearance in the blast zone to work around longer muzzle devices (brakes, flash hiders, and suppressors up to roughly 3 inches). The improved three-button display is intuitive to operate, runs on either a 9-volt or CR123 batteries (both easy-swap without tools), and has been refined with a more compact, rugged housing that can handle the rigors of the range or field. Dual data connection points and downloadable firmware updates keep the system current, while advanced data logging and troubleshooting features give serious reloaders and precision shooters the tools to extract maximum insight from their velocity data.

This kit includes everything you need: the display unit, both a standard 6-foot and retractable connection cable, a stainless steel blast shield, thick and thin rubber V-block spacers for different barrel profiles, the bayonet sensor assembly, a complete polymer spacer kit, a heavy-duty strap with thumb nut tightener, and a custom-cut hard case for safe transport and storage.
