Built on the proven Radikal NK-1 platform, the GFY-1 puts an 18.5" barrel into a 28.5" overall package by moving the action and magazine behind the trigger in classic bullpup configuration-keeping the platform short and maneuverable without sacrificing barrel length. The gas-operated action chambers 3" shells and feeds from AR-12 pattern magazines and drums, giving the GFY-1 broad aftermarket support for capacity and accessories. The aluminum fore-end carries Picatinny rails on both top and bottom for optics, lights, and other accessories, and flip-up sights are included. The threaded barrel accepts Mobil Benelli-style chokes, with a MOD choke installed from the factory. OD Green polymer stock with A2-style pistol grip.
