The MagnetoSpeed Large Brake Adapter is engineered to accommodate extended muzzle devices commonly found on large-caliber rifles such as .338 and .50 BMG. It enables the MagnetoSpeed V3 ballistic chronograph to be used with muzzle brakes up to 20 cm in length and barrels up to 4 cm in diameter at the muzzle.

The package includes:

• the Large Brake Adapter;
• the V3 Rail Adapter for Picatinny-rail mounting.

Crafted from precision-machined 6061 aluminum, the adapter attaches directly to the barrel, ensuring a secure and stable platform for the V3 bayonet — even on powerful long-range rifles.

The included V3 Rail Adapter expands the compatibility of the MagnetoSpeed V3, allowing it to be mounted on most pistols and short-barreled rifles equipped with Picatinny rails.
