Stevens 320 Security 12 Gauge Pump Shotgun, 18.5” Ghost Ring, Customized Magpul Forend & Collapsible Stock
The Stevens Model 320 Security Ghost Ring Sight edition is a full-size 12 gauge pump shotgun built around a proven dual-action-bar design and a 3” chamber. This example stands out with user-installed Magpul furniture, a collapsible stock, and a fiber-optic/ghost-ring sight system that make it adaptable for close-quarters defensive use.
Condition
Overall Condition: Fair – shows extensive signs of prior use and handling.
Bore Condition: Good – bore is bright, clean, and well-maintained with minor wear.
Specific Condition Notes: The six-position collapsible buttstock and pistol grip are secured to the receiver with a non-factory epoxy adapter. A vertical polymer fore-grip is attached to the Magpul M-LOK forend. The pump action feels stiff and may require additional cycling to smooth out.
What’s Included
- Stevens Model 320 Security 12 Gauge pump shotgun with 18.5” cylinder-bore barrel
- Magpul polymer M-LOK forend with attached vertical fore-grip
- Six-position collapsible polymer buttstock with pistol grip
- Factory ghost-ring rear sight and green fiber-optic front post
Designed around the Winchester 1200/1300 rotary-lock lineage, the 320 uses dual action bars for consistent lock-up and smooth cycling. The 18.5” cylinder-bore barrel pairs with a 3” chamber, giving the shooter flexibility with both 2 ¾” and 3” defensive loads.
The Magpul M-LOK forend provides multiple mounting slots for lights or rails, while the installed vertical grip offers added leverage during rapid cycling. Combined with the collapsible stock’s 12” length of pull, the shotgun can be adjusted quickly for different shooters or confined spaces.
Bright ghost-ring sights—green fiber-optic front and elevation-adjustable rear—deliver a clear sight picture in low light. The cross-bolt safety is positioned behind the trigger guard for familiar, glove-friendly operation.
Weighing approximately 6.8 lb in factory trim, the 320 remains maneuverable even with the added furniture. Its matte-black aluminum-alloy receiver and carbon-steel barrel keep glare to a minimum while standing up to regular range use.
