Genesis Arms Gen-12 SBM w/ Adaptive Stock, 12ga, 5" Barrel, 2.75" Chamber, 1- 5rd Magazine, FDE, Suppressed Short Barreled Shotgun

Genesis Arms GEN-12 SBM 5-Inch Suppressed Short-Barreled Shotgun - FDE

The Genesis Arms GEN-12 SBM in FDE pairs a 5-inch, 12 gauge semi-automatic short-barreled shotgun with an included HUX VENTUM 12K suppressor. Its Flat Dark Earth color distinguishes this compact package, while short-recoil operation, an Adaptive Tactical stock and a Hogue rubberized grip define the configuration. The chamber accepts 2.75-inch shells only, and one 5-round magazine is supplied.

Choose this FDE GEN-12 SBM for an earth-tone shotgun setup with the suppressor already included in the package. The free-float handguard combines M-LOK mounting positions with a full Picatinny top rail, giving the compact platform clearly defined accessory interfaces. The package also includes a soft case and a limited warranty.

5-Inch Barrel with a 2.75-Inch-Only Chamber

The 5-inch barrel is the defining feature of this GEN-12 SBM short-barreled shotgun. Its 12 gauge chamber is limited to 2.75-inch shells; it does not accept 3-inch shells. Keeping that chamber specification clear is essential when selecting ammunition for this compact configuration. The muzzle thread specification is 1.375-24.

Included HUX VENTUM 12K Suppressor

A HUX VENTUM 12K suppressor is supplied with the shotgun. The package brings the GEN-12 SBM and this named suppressor together in one purchase, making the suppressor a central part of the configuration. Confirm any additional accessories against the specific shotgun and suppressor requirements.

Short-Recoil Action and GEN1 DPMS-Pattern Lower

The GEN-12 SBM uses short-recoil operation and a GEN1 DPMS .308-pattern lower. A mil-spec AR trigger gives the platform a familiar trigger format. The buffer system consists of a mil-spec buffer tube and a 3.8-ounce .308 short carbine buffer. The lower's .308 pattern describes its platform architecture; this firearm is chambered in 12 gauge.

Adaptive Tactical Stock and Hogue Grip

The Adaptive Tactical stock establishes a shoulder-supported shooting interface, complemented by the textured feel of a Hogue rubberized grip. These two contact points help the compact GEN-12 SBM feel familiar to shooters accustomed to a separate stock and pistol grip. The FDE color provides an earth-tone alternative for coordinating the shotgun with similarly colored gear.

Free-Float Handguard with M-LOK and Picatinny Interfaces

The free-float handguard provides M-LOK mounting positions at 3, 6 and 9 o'clock, plus a full Picatinny top rail. These distinct interfaces support compatible accessories along the sides, underside and top of the handguard. Check the mounting interface and available clearance when selecting accessories for the short configuration.
