THE FIX & mini FIX are chassis-less, magazine fed, 45 degree throw bolt-action firearms intended for use by hunters, competitors, recreational shooters, and armed professionals alike. The unique one-piece receiver provides superior rigidity over multi-piece platforms and chassis, while reducing the amount of bulk and weight common in traditional bolt-action platforms. The receiver houses the trigger mechanism, bolt assembly, and barrel. Attached to the receiver are the grip, adjustable stock, handguard, and continuous (zero MOA) M1913 picatinny top rail.
