The GForce Arms 12HAMMER is a 12 gauge semi-automatic shotgun with an 18.5-inch barrel and a 5+1 capacity (brand part no. GF12HMRB). GForce Arms designed it around a gas-operated buffer tube system that cycles without the high-velocity loads many Turkish-made shotguns of this style need, so light birdshot through 3-inch steel and T-shot are all on the menu. A forged aluminum upper, polymer lower and monoblock synthetic stock keep the gun durable without making it heavy. The Benelli Mobil choke threading at the muzzle lets you match the pattern to the job. It suits home defense, range work and sport shooting alike.
