MagnetoSpeed Large Brake Adapter for V3 Chronograph Barrels to 1.6 in and Brakes 7.7 in

The MagnetoSpeed Large Brake Adapter enables use of the V3 Chronograph with muzzle brakes up to 7.7" in length and barrel diameters up to 1.6" at the muzzle, making it an ideal accessory for precision-focused rifle shooters working with large calibers. Designed to compensate for longer muzzle brakes commonly found on rifles chambered in .338 and .50 BMG, this milled 6061 aluminum fixture provides rugged, reliable performance in the field or on the bench. The Large Brake Adapter uses the included V3 Rail Adapter to clamp securely onto your weapon's barrel, allowing seamless integration with the V3 Chronograph's bayonet for quick setup and repeatable measurements. This solution expands the versatility of the MagnetoSpeed system, delivering consistent muzzle velocity data even when outfitting your rifle with substantial compensators. Please note that the MagnetoSpeed V3 Chronograph is not included, so you can pair this adapter with your existing unit to unlock precise ballistic data across a range of large-caliber configurations. Built to endure rigorous field use, the adapter supports accurate tracking of muzzle velocities, enabling informed load development and performance evaluation for long-range applications.
