TriStar Compact Tactical Bullpup 12 Gauge Shotgun
Pros & cons
What works
- 30-inch overall length — 25% shorter than a standard 40-inch shotgun for indoor maneuverability.
- Includes two 5-round magazines — enables a 10-round total capacity with a quick reload.
- Gas-operated semi-auto action — reduces perceived recoil by approximately 30% versus a pump-action like the Mossberg 500.
- 18.5-inch barrel with Mobil choke threads — permits patterning flexibility from cylinder to improved cylinder for different loads.
Trade-offs
- Bullpup trigger linkage — results in a heavier 8-9 pound pull weight with noticeable creep, impacting precision.
- Proprietary magazines — limits aftermarket options and requires purchasing spimes directly from TriStar or specific retailers.
- Synthetic stock finish — has a utilitarian, matte texture that shows wear scratches more readily than a textured polymer like Magpul's.

About this product
TriStar Compact Tactical Bullpup 12 Gauge Shotgun
The TriStar Compact Tactical Bullpup is a gas-operated, semi-automatic 12 gauge shotgun that places its action and magazine behind the trigger group for a 30-inch overall length, granting it ballistic authority without the cumbersome length of a traditional shotgun. This bullpup configuration prioritizes maneuverability in confined spaces and uses a modular choke system. It delivers magazine-fed convenience and a full suite of tactical features like flip-up sights and a fixed carry handle for immediate employment.
What is the TriStar Compact Tactical Bullpup used for?
This shotgun is engineered for close-quarters applications, home defense, and practical/tactical training on short-range courses. Its 30-inch overall length makes it easier to manipulate in vehicles, tight hallways, or barricaded shooting positions compared to a standard 40-inch pump-action. The gas-operated semi-auto action and included spare magazine support rapid follow-up shots, although consistent function depends on using quality ammunition at the proper firing impulse for its system.
How does the TriStar Compact Tactical Bullpup compare to the Stevens 555 Sporting O/U 12 Gauge?
The TriStar bullpup is categorically better for dynamic defense scenarios, while the Stevens 555 Sporting is superior for breaking clay targets. The TriStar offers faster reloads via its two included 5-round detachable magazines and a 30-inch overall profile that is 10 inches shorter than the Stevens 555 Sporting O/U (which is 40 inches long), making it vastly easier to pivot and maneuver indoors. For controlled, deliberate shooting at clay or game, the break-action Stevens provides superior balance and pointability.
What does it weigh and what are the dimensions?
The shotgun weighs approximately 7.5 pounds unloaded and measures 30 inches from muzzle to the end of its rubber recoil pad. This specific length and weight distribution, with mass concentrated rearward, creates a distinct feel; it pivots quickly but can feel muzzle-light compared to a traditional shotgun. The barrel length, critical for velocity and patterning, is 18.5 inches, and it uses a Beretta/Benelli Mobil choke thread pattern for aftermarket compatibility.
Who is this NOT for?
This is not for the shotgunner seeking a traditional field gun for hunting waterfowl or upland game over long distances. The short barrel and ported cylinder choke sacrifice tight, consistent long-range patterning, and its tactical ergonomics are ill-suited for carrying afield all day. It's also not ideal for a first-time shooter, as the bullpup trigger linkage typically results in a heavier, less crisp pull than a standard configuration, which can hinder marksmanship fundamentals.
What's in the box?
The package includes the assembled shotgun, two 5-round polymer magazines, an extended ported cylinder-bore choke tube installed in the barrel, and the choke wrench. Unlike some higher-end packages, it does not include a sling or optic; Ironclad Armory sells compatible aftermarket accessories separately. The magazines are proprietary to this model, so spares should be purchased immediately if this is a serious-use firearm.
Is the TriStar Compact Tactical Bullpup worth it at $710.99?
At this price point, it offers significant value as a functional, magazine-fed tactical platform that avoids the $1,200+ entry fee of competing bullpup designs. You are paying for the compact form factor and semi-auto functionality, accepting trade-offs in trigger feel and a synthetic stock that prioritizes durability over aesthetic refinement. For a shooter building a dedicated home defense tool, it is a cost-effective entry. For someone wanting a do-everything shotgun, consider the more versatile but longer Stevens 334 rifle platform for similar investment.

Frequently asked questions
- Is it compatible with Beretta chokes?
- Yes. It uses the common Beretta/Benelli Mobil choke thread pattern (often abbreviated as "Mobil choke" or "Benelli/Beretta"). The included choke is an extended ported cylinder bore tube, but you can install any aftermarket choke rated for 12 gauge and 3-inch shells with that thread pattern, such as those from Carlson's or Patternmaster.
- Does it fit in a standard 32-inch rifle case?
- Yes. With an overall length of 30 inches, it will fit comfortably in most 32-inch takedown rifle cases or tactical bags. You'll need to account for the width of the fixed carry handle when selecting a hard case—measure roughly 9 inches at the widest point across the receiver.
- Can I return it if it doesn't function properly?
- Ironclad Armory's policy is a 30-day return window for un-fired firearms in original packaging, subject to a 15% restocking fee. If the firearm exhibits a mechanical defect, you must contact customer service for an RMA and ship it directly to TriStar's warranty service center in Kansas City, MO, which typically handles repairs within 10-14 business days.
- Does this work with mini-shells or 2.75-inch shells?
- It fires standard 2.75-inch and 3-inch 12 gauge shells. It will NOT cycle Aguila Mini-Shells or other sub-length rounds reliably without an aftermarket adapter, which we do not recommend for a gas-operated system. For reliable semi-automatic function, use quality 2.75-inch or 3-inch shells with a dram equivalent of 3 or higher.
