Key Features
- Mobil-thread Choke System — Why it matters: You can instantly switch between tight patterns for long-range turkeys and open spreads for close-flushing quail without buying a second barrel.
- Fiber-Optic Front Sight — Why it matters: In low-light dawn hunts or against a bright clay sky, the bright dot lets you acquire targets faster than traditional bead sights.
- Rubber Recoil Pad — Why it matters: Reduces felt recoil by about 30% compared to hard plastic buttplates, keeping you on target for longer practice sessions or heavy 3-inch magnum loads.
- Swivel Studs — Why it matters: Attach a sling for hands-free carry during long walks through CRP fields or marsh boardwalks.
- 5+1 Capacity with 3-Inch Chamber — Why it matters: Load five shells plus one in the chamber for extended strings on the trap range or follow-up shots on driven birds.
Who It’s For
This shotgun targets the tech-savvy early adopter who values modularity and modern manufacturing over vintage wood-and-blue. It’s ideal for budget-conscious hunters who want a reliable pump with a proven choke system, for clay shooters who shoot 100+ rounds per session, and for first-time shotgun buyers who want a platform that can grow with them. If you already own Beretta or Benelli Mobil-choke accessories, this gun seamlessly integrates with your existing tube collection.
Pros & Cons
- Pro: Choke-tube versatility lets you dial in patterns for everything from skeet to steel shot waterfowl.
- Pro: Lightweight 7.2-lb build reduces fatigue during all-day hunts.
- Pro: Affordable price point leaves room in the budget for ammo and aftermarket upgrades.
- Con: The fixed synthetic stock lacks length-of-pull or comb height adjustability, so taller or shorter shooters may need a aftermarket stock or recoil pad spacer.

The TriStar Cobra III undercuts both the Mossberg 500 and Remington 870 by $44–$74 while offering a fiber-optic sight and a choke system that shares threads with the popular Beretta/Benelli ecosystem. The trade-off is a fixed stock versus the adjustable options on some Mossberg models.
FAQ
What choke tubes does the TriStar Cobra III use?
It uses the Beretta/Benelli Mobil-thread pattern (also called ‘Mobil’ or ‘Benelli Mobil’). The shotgun ships with three tubes: Full, Modified, and Improved Cylinder. You can swap in any aftermarket Mobil-thread tube for specialty loads like steel or tungsten.
Can the TriStar Cobra III shoot 3-inch magnum shells?
Yes. The chamber is rated for 2.75-inch to 3-inch shells, including magnum loads. The rubber recoil pad helps manage the extra kick from heavy 3-inch waterfowl or turkey loads.
Is the stock adjustable?
No. The stock is a fixed-length synthetic design. If you need a shorter or longer length of pull, you’ll need an aftermarket stock or a recoil pad spacer. The swivel studs are pre-installed for sling attachment.
Does the TriStar Cobra III come with a choke wrench?
Yes. TriStar includes a steel choke wrench in the box to remove and install the tubes. Keep it with your choke case for field adjustments.
