The Iver Johnson Arms Stryker 1 12 Gauge Semi-Auto – 5+1, 20" Black Steel Barrel, Black Picatinny Rail Receiver, Adjustable Cheekrest Black Synthetic Stock (Model STRYKER1, UPC 796167791898) is a modern, magazine-fed AR-style shotgun built for home defense, tactical training, and range fun. With its 20" steel barrel, mag-fed semi-auto action, dual Picatinny rails, and adjustable cheekrest, the Stryker 1 delivers a versatile, customizable platform at an affordable price.
Semi-Auto, Mag-Fed 12 Gauge Performance
The Stryker 1 is a semi-automatic, magazine-fed 12 gauge shotgun designed to give you fast follow-up shots and easy reloads:
Action: Semi-auto, gas-operated mag-fed system for quick cycling and reduced manual work between shots.
Capacity: 5+1 rounds of 12 gauge, using detachable box magazines (includes two 5-round mags from the factory).
Chamber: 3" chamber to handle standard 2¾" loads and 3" magnum shells for added versatility.
For home defense, range work, or tactical drills, a mag-fed semi-auto like the Stryker 1 provides rapid, repeatable firepower with minimal downtime.
20" Black Steel Barrel with Removable Internal Chokes
The Stryker 1’s 20" black steel barrel hits the sweet spot between maneuverability and effective patterning:
Barrel Length: 20" – short enough for easier handling indoors or around obstacles, yet long enough for solid patterns and velocity.
Material: Durable steel barrel built to withstand heavy 12 gauge use.
Finish: Black for a sleek, non-reflective tactical appearance.
Removable internal chokes (included) let you tailor your pattern for close-quarters buckshot, mid-range birdshot, or slugs.
Whether you’re busting clays, running drills, or setting up a defensive shotgun, adjustable choke options make the Stryker 1 more flexible.
AR-Style Picatinny Rail Receiver & Aluminum Forend with Rails
The Black Picatinny rail receiver and railed forend give the Stryker 1 a modern AR-style layout:
Top Picatinny sight rail for mounting red-dots, holographic sights, or scopes to fit your mission.
Bottom accessory rail on the aluminum forend for lights, vertical grips, or handstops—ideal for low-light defensive setups.
Ships with flip-up front and rear sights as backup or primary aiming solutions right out of the box.
This AR-style rail configuration makes it simple to configure the Stryker 1 exactly the way you like it.
Adjustable Cheekrest & Black Synthetic Stock for Custom Fit
Comfort and fit are critical when shooting 12 gauge. The Stryker 1 solves this with a fixed synthetic stock featuring an adjustable cheekrest:
Fixed stock with adjustable cheekrest lets you dial in cheek height for your optic or irons, improving eye alignment and shot-to-shot consistency.
Black synthetic stock and ergonomic polymer pistol grip resist moisture, rough handling, and temperature swings.
Designed to help manage recoil and maintain a solid shoulder weld during rapid strings.
From smaller shooters to larger-framed operators, the adjustable cheekrest makes this shotgun easier to shoot comfortably and accurately.
Lightweight, Balanced, and Easy to Handle
Despite being a 12 gauge semi-auto, the Stryker 1 stays manageable:
Overall length: about 38", making it compact enough for home defense and vehicle use.
Weight: approx. 7.11 lbs unloaded—light enough to maneuver quickly but heavy enough to help soak up recoil.
Length of pull: around 14.25", giving most adult shooters a natural fit.
Balanced dimensions make the Stryker 1 a good choice for extended range sessions and dynamic training.
Flip-Up Sights & Optics-Ready Versatility
The Iver Johnson Stryker 1 ships ready to run with irons or optics:
Flip-up front and rear sights provide a clear sight picture and fold down when not in use or when you’re running an optic.
The top Picatinny rail allows quick mounting of red-dot sights for faster target acquisition and better low-light performance.
This flexibility is ideal for shooters who want to start with irons and upgrade to optics later—or run both as backup.
Ideal for Home Defense, Tactical Training & Range Use
With its semi-auto mag-fed design, adjustable stock, and rail-ready layout, the Stryker 1 is an excellent choice for:
Home defense: 5+1 capacity, quick reloads with detachable magazines, and easy optics/light mounting options.
Tactical & competition-style training: AR-like controls and ergonomics make transitioning from carbines to shotgun smoother.
Range & recreational shooting: manageable weight, adjustable cheekrest, and removable chokes keep it fun and versatile.
If you want one semi-auto 12 gauge that covers defensive, training, and sport roles, the Stryker 1 is built for multi-purpose performance.
