Iver Johnson Stryker 12 Gauge Shotgun Overview
The Stryker brings the familiar AR-15 layout to the 12 gauge, so AR owners can pick it up and run it without learning a new manual of arms. It has a standard AR-15 style bolt release and magazine release, a cross trigger safety and a pistol grip, and it feeds from MKA 1919 pattern 5 round box magazines, two of which are included. The 20 inch smooth bore barrel accepts 2 3/4 and 3 inch shells and wears a muzzle brake to tame recoil.
A detachable A2 style carry handle with an adjustable rear sight sits on the Picatinny top rail, and a fiber optic front sight gives a bright aiming point. The synthetic forend has accessory rails on the sides and bottom for lights and grips. 25 inch length of pull and a 43 inch overall length.
AR Style Ergonomics
If you already own an AR-15, the Stryker’s controls, pistol grip and rail system will feel natural. That makes it a great home defense or 3 gun style shotgun for shooters who train with an AR.
Magazine Fed Speed
Detachable 5 round box magazines make reloading fast, and you can keep spare magazines loaded with buckshot or slugs. Additional Stryker magazines are available separately.
Setup Tips
Mount a red dot or light on the rails, pattern your defensive load and practice magazine changes. Keep the gas system and bolt clean and lightly lubricated for reliable function. Not legal in California.
Choosing Shells
Pattern your shotgun with several loads at the distances you expect to shoot, since every barrel and choke combination behaves differently. Use the right shot size for your game or target and follow local rules on nontoxic shot where required.
Fit and Mounting
A shotgun that fits lets you look straight down the rib with your cheek firmly on the stock. Practice smooth gun mounts at home with an unloaded gun to build consistency in the field and on the clay range.
Care and Maintenance
Clean the bore, chokes and action after each outing, especially after rain or salt water. A light coat of oil on metal parts and a clean action keep the shotgun running reliably for years.
Choke Selection
Tighter chokes such as modified and full extend effective range for waterfowl and turkey, while improved cylinder and skeet chokes open patterns for close birds and clay targets. Always use chokes rated for the shot you are shooting, especially steel.
Recommended Accessories
Eye and ear protection, a cleaning kit, extra choke tubes and a padded case are smart additions. Hunters may want a sling, while clay shooters often add a shell pouch and recoil reducing pad.
