Description
The Iver Johnson Stryker-1 takes the familiar AR layout and puts it to work in 12 gauge. Instead of shoving shells through a loading gate one at a time, you swap a box magazine and get back on target. It ships with two 5-round mags, so you can keep one topped off while you run the other, and the 3 inch chamber handles everything from light birdshot up to full-power buckshot and slugs. The 20 inch steel barrel gives payloads a little extra room to build velocity while keeping the whole package right around 7 pounds.
Built Around the Stryker-1's AR-Style Controls
If you already run an AR, the Stryker-1 will feel like home. The pistol grip, magazine release, and general handling all carry over, which makes it a natural pick for anyone who wants a shotgun without relearning their muscle memory. The fixed synthetic stock has an adjustable cheek rest so you can dial in a proper cheek weld whether you're looking through the included flip-up sights or an optic you mount yourself. Length of pull sits at 14.25 inches, a comfortable fit for most adult frames.
Rails, Sights, and Room to Customize
The receiver wears a full-length Picatinny rail up top, and the forend adds a bottom accessory rail for a light, laser, or vertical grip. Flip-up front and rear sights come standard, so the gun is usable the day you bring it home, and they fold out of the way once you add a red dot. Removable internal chokes let you tighten or open up your pattern depending on what you're feeding it.
Where the Stryker-1 Earns Its Keep
This is a fun, practical range gun that pulls double duty for home protection. Mag-fed semi-auto shotguns turn a box of buckshot into an entertaining afternoon, and the quick reloads keep the pace up when you're running drills or knocking down steel. For the money, the Stryker-1 packs a lot of features into a rugged black package.

Frequently Asked Questions
What magazines does the Iver Johnson Stryker 1 use?
The Stryker-1 ships with two 5-round detachable box magazines. It runs on the common MKA 1919 / AR12 magazine pattern, which is widely available from multiple makers, so finding spares or higher capacity options is easy. Iver Johnson also sells factory magazines directly.
Can the Stryker-1 shoot both 2-3/4 inch and 3 inch shells?
Yes. The 3 inch chamber accepts both 2-3/4 inch and 3 inch 12 gauge loads, from birdshot to buckshot and slugs. As with most gas-operated semi-auto shotguns, it tends to cycle most reliably with full-power loads, so feed it stouter ammo during break-in before switching to lighter target shells.
Can I mount a red dot or other optic on the Stryker 1?
Absolutely. The receiver has a full-length Picatinny rail up top that accepts red dots, holographic sights, or a low-power scope. The included flip-up sights fold down out of the way when an optic is mounted, and the bottom accessory rail handles a light or foregrip.
Is the Iver Johnson Stryker-1 good for home defense?
It's a solid fit for that role. The mag-fed design means fast reloads, the 5+1 capacity of 12 gauge is serious stopping power, and the rails let you add a weapon light, which is a smart move for any home defense setup. The AR-style controls also make it easy to handle if you already train on that platform.
