Key Features
- 18.5-inch Barrel – Why it matters: Short enough to swing fast in tight spaces, long enough to keep your pattern tight at 25 yards.
- Beretta/Benelli Mobil Choke System – Why it matters: You can swap chokes for buckshot, slugs, or birdshot without buying a whole new barrel. Ships with a cylinder choke for close-range work.
- Forearm-Mounted Picatinny Rail – Why it matters: Mount a light or laser directly on the forend without aftermarket adapters. Keeps your support hand in control.
- Forearm Return Spring – Why it matters: Speeds up the pump cycle so you can rip follow-up shots faster. Less chance of short-stroking under stress.
- Fixed Synthetic Field Stock with Rubber Recoil Pad – Why it matters: No wobble or looseness over time. The pad soaks up 12-gauge recoil, keeping you on target for longer range sessions.
Who It’s For
This shotgun is for the shooter who needs a reliable home-defense or range gun at a practical price. It works for new shooters learning the pump action, for hunters who want a compact brush gun, and for anyone who wants a tactical 12-gauge without the premium price tag. If you run drills with buckshot and slugs, the forearm return spring and Pic rail make it a solid choice.
Pros & Cons
- Pro: Affordable price point – under $260 for a tactical 12-gauge with a choke system and rail.
- Pro: Forearm return spring reduces short-stroke risk during rapid fire.
- Pro: Beretta/Benelli Mobil chokes give you pattern flexibility.
- Con: Fixed stock limits LOP adjustment for smaller or larger shooters. You’ll need a stock adapter or aftermarket pad if it doesn’t fit.

The TriStar Cobra III Tactical undercuts both the Mossberg 590 and Remington 870 on price while adding a choke system and factory Pic rail. You lose the aftermarket parts volume of the 870, but for the money, this gun runs.
