What’s Included
- Mossberg 930 SPX 12 Gauge semi-automatic shotgun
This 930 SPX uses a gas-operated, semi-automatic action paired with an 18.5 inch steel barrel cut to a cylinder bore. It is chambered for both 2 3/4 and 3 inch shells, giving you flexibility across common 12 gauge loads while maintaining the compact overall length of the SPX pattern.
The sighting system is set up with an LPA Italy-marked ghost-ring rear sight; the barrel features a front sight base/tower (no front post/insert installed). A receiver rail/scope mount is installed, providing a solid mounting surface on the top of the receiver.
Feeding is through an under-barrel tubular magazine with an extension for a 6+1 capacity. The magazine extension terminates short of the muzzle, keeping the profile clean and consistent with the 18.5 inch barrel length.
Controls and furniture are built for practical handling: an oversized, knurled charging handle for confident manipulation; a black synthetic stock with a ventilated recoil pad and sling swivel studs; a conventional pistol-grip profile; and a matching black synthetic fore-end. Length of pull is 14.0 inches.
The aluminum alloy receiver wears a matte black finish to match the barrel and furniture, offering a durable, low-glare exterior. Materials and finish choices balance strength and weight for a shotgun designed to run reliably.
