About this product

It is built for modular use: the barrel is removable to reduce overall length for storage or to enable caliber conversion with a bolt face and barrel change. This configuration includes a 1913-style brace adapter for use with a folding brace (all applicable NFA laws apply) and a 1/2×28 threaded muzzle for suppressor-ready accessories. The platform is optics-ready via an integral Picatinny rail and is manufactured in the USA by a veteran-owned company.
