TriStar TT-15 Unsingle 12 Gauge 34″ Trap Shotgun Walnut
Pros & cons
What works
- 34-inch barrel with 3-point adjustable rib provides a 51.18-inch sight plane for precise target tracking
- Walnut stock with adjustable comb and palm swell offers 0.75 inches of vertical adjustment for consistent eye alignment
- Includes three extended Beretta/Benelli Mobil chokes (F, IM, M) for immediate pattern tuning at the range
Trade-offs
- 1-round capacity and break-action design mandate a full manual reload cycle after every shot
- 8.2-pound weight is purposefully forward-heavy, making it feel sluggish for off-hand or fast mount shooting
- No included hard case—transport requires a separate purchase of a fitted shotgun case

About this product
The TriStar TT-15 Unsingle 12 Gauge 34″ Trap Shotgun Walnut is a dedicated single-shot break-action shotgun engineered for formal trap shooting, featuring a 34-inch barrel with an adjustable target rib, a walnut stock with adjustable comb and palm swell, and a 1-round capacity. This configuration prioritizes consistent mounting and precise shot placement over high-volume fire, adhering to competitive specifications that often forbid magazine-fed systems on the trap line. Its 51.18-inch overall length and regulated 2.75-inch chamber make it a purpose-built tool for a specific discipline, where repeatable mechanics trump raw firepower.
What is the TriStar TT-15 Unsingle used for?
The TT-15 Unsingle is used exclusively for formal trap shooting under ATA or other governing body rules. Its single-shot break-action design enforces the deliberate pace required for the discipline, while the 34-inch barrel and adjustable rib provide the long sight plane and precise point-of-impact adjustment necessary for breaking targets at regulated distances. This shotgun is a poor choice for hunting or home defense due to its 1-round capacity and specialized weight-forward balance meant for a smooth, controlled swing from a fixed station.
How does the TriStar TT-15 compare to the Stevens 555 Sporting O/U?
The TriStar TT-15 is a superior choice for a dedicated trap shooter seeking a pure single-barrel feel and maximum adjustability, while the Stevens 555 Sporting O/U is a more versatile budget over/under for a multi-discipline shooter. The TT-15’s adjustable comb and three-point rib offer finer tuning for an individual’s mount and vision, whereas the Stevens 555 provides a second immediate shot but lacks those micro-adjustments and has a shorter 30-inch barrel. For the singular task of breaking trap targets from the 16-yard line, the TT-15’s dedicated ergonomics provide a tangible mechanical advantage, but if you also shoot skeet or sporting clays, the over/under action of the Stevens 555 is the more practical platform.
What does it weigh and what are the dimensions?
The TriStar TT-15 Unsingle weighs approximately 8.2 pounds (3,719 grams) and measures 51.18 inches in overall length with a 34-inch barrel. This weight is distributed forward of the receiver, a deliberate design to dampen muzzle flip and promote a steady follow-through after the shot. The barrel's 10mm raised rib creates a clear sighting plane, and the walnut stock has a length of pull adjustable from approximately 14.25 to 15.5 inches via spacers, accommodating a wide range of shooter statures.
Who is this NOT for?
This shotgun is not for hunters, home defenders, or casual clay shooters who value versatility. The mandatory single-shot reload cycle makes it useless for flushing birds or defensive scenarios, and its niche configuration offers no benefit for informal shooting. If your range time involves shooting a box of shells at stationary targets from various positions, you will find its deliberate operation and specialized balance more limiting than a standard field or sporting model review. This is a competition tool, not a general-purpose firearm.
What's in the box?
The package includes the shotgun, three color-coded extended Beretta/Benelli Mobil choke tubes (Full, Improved Modified, Modified), a set of stock adjustment spacers, and the necessary wrenches. These extended chokes protrude approximately 1.5 inches from the muzzle, allowing for tool-less hand-tightening and quick changes between trap disciplines. Notably absent is a hard case; expect a cardboard box with foam inserts, which is standard at this price point for a dedicated competition gun where buyers typically use their own fitted luggage.
Is the TriStar TT-15 Unsingle worth it at $1594.99?
At $1,594.99, the TT-15 Unsingle is worth it for the serious trap shooter who understands the value of its adjustable features and is committed to the single-barrel discipline. You are paying for the precision-machined adjustable rib and comb system, which on custom guns can cost nearly this much alone, integrated into a ready-to-shoot platform. For a recreational shooter or someone wanting a first over/under, this price puts you in direct competition with established Turkish imports and used Browning or Beretta O/Us, where the versatility trade-off becomes significant. It's a focused investment for a focused shooter.

Frequently asked questions
- Is it compatible with standard Beretta/Benelli choke tubes?
- Yes, the TriStar TT-15 uses the Beretta/Benelli Mobil choke threading system, which is an industry standard. The included tubes are extended, but any Mobil-pattern choke (like those from Carlson's or Briley) will fit. The barrel is threaded for the full length of the choke tube, not just the last few threads, providing a secure and concentric fit.
- Does the fiber optic front sight require batteries?
- No, the fiber optic front sight is a passive light-gathering rod and requires no batteries, tools, or power source. The 1.5mm green fiber collects ambient light, creating a bright aiming point. The sight is housed in a steel ramp that is drift-adjustable for windage zeroing at the range.
- Can the adjustable comb be locked in position?
- Yes, the adjustable comb uses a series of set screws accessed via side ports in the stock to lock its height and cant firmly in place. Once set to your preferred cheek weld, it should not shift under recoil. The adjustment range is approximately 0.75 inches vertically, which is sufficient for most facial structures and optic mounts.
- How long does shipping take to an FFL?
- Shipping typically takes 3-7 business days from our warehouse to your selected FFL dealer, depending on your location. All firearms must ship to a licensed dealer for the mandatory 4473 background check transfer. You will receive tracking information via email once the item ships from our facility.
