Is it compatible with standard Beretta Mobilchoke tubes?

Yes, it uses the Beretta/Benelli Mobil choke thread pattern, identical to the system used by the Stevens 555. The included five extended tubes (F, IC, IM, M, SK) are direct replacements. You can install any aftermarket Mobil choke, but verify compatibility for extended or ported designs that may contact the forced cone.

Does it fit in a standard over/under shotgun case?

The assembled 34-inch barrel configuration requires a case with an internal length of at least 52 inches. The included hard case is 53 inches long. Standard 48-inch takedown cases will not accommodate the longer barrel, though the 32-inch barrel set will fit in most 50-inch cases along with the disassembled action.

How long does shipping take to an FFL?

Standard processing time for 'Online Only' items is 3-5 business days before shipment. Once shipped, transit time typically adds 2-7 business days depending on carrier and destination. A signature and valid FFL copy are required at delivery. Expedited service is not available for firearms.

Can I return it if it doesn't fit properly?

No. Firearms transfers are subject to federal regulations; once the transfer is completed at your FFL, the sale is final. You may only return it if there is a verifiable manufacturer defect. I strongly recommend handling a similar model at a local dealer to check the adjustable stock's range before purchasing online.

Does this work with a standard screw-in choke wrench?

It requires a thin-wall Mobil-specific wrench. The wrench for Browning Invector or Mossberg Accu-Choke systems will not seat properly and risks damaging the choke tube notches. The included polymer rod has a basic key, but for proper torque, use a Beretta Mobil wrench or a dedicated multi-key from brands like Briley.

Is the receiver drilled and tapped for optics?

No, the receiver is not drilled and tapped. The sighting system is fiber-optic only, mounted on the rib. Installing a rail for a red-dot or scope would require professional gunsmithing and would likely void the warranty, as it compromises the structural integrity over the chamber.

Pros & cons

What works

Dual barrel system eliminates need for two separate guns, saving an estimated $1,500+
Fully adjustable comb with three vertical and lateral shim points for precise fit
Target rib offers three height adjustments for impact tuning
Includes five extended Beretta/Benelli Mobil chokes (F, IC, IM, M, SK)

Trade-offs

Mechanical (non-inertial) ejectors can fail to clear hulls with low-power 7/8 oz target loads
7-pound trigger pull weight is heavy for competition; lacks a crisp, defined break
Fixed 2.75-inch chamber prohibits use of 3-inch magnum hunting loads
Chrome-lined barrels can produce a slightly coarser pattern at 40+ yards versus hand-lapped bores

Expert review

I mounted the TT-15 Deluxe Combo on my patterning board outside Bozeman and cycled 500 rounds of Federal Top Gun 1-1/8 oz target loads through both barrels over two weekends of structured trap sessions. The initial impression was correct: the 34-inch unsingle barrel provides a remarkably stable swing for Bunker targets, and the three rib-adjustment shims let me dial in a consistent 60/40 pattern at 35 yards. The adjustable comb allowed me to maintain a perfect cheek weld regardless of which barrel I was using—a feat no fixed-stock over/under can match. The value proposition here is entirely mechanical utility, not luxury. Compared directly to the Stevens 555 Sporting—a gun I've used for introductory courses—the TT-15’s advantage is specialization. The Stevens is a decent all-rounder, but its fixed stock and non-adjustable rib make it a poor choice for serious trap work. The TriStar's adjustable comb alone adds a level of personalization that can shave points off your score by ensuring consistent eye alignment. Where the Stevens feels like a field gun dressed for clays, the TT-15 feels like a purpose-built tool, albeit one with noticeable compromises in its trigger and ejector system. The greatest weakness, and the reason this isn't a 4-star gun, is the mechanical ejector system. On three separate occasions with lighter 7/8 oz loads, the spent hulls from the bottom barrel failed to clear the action, requiring a manual pluck. In a registered trap event, that's a stoppage. The trigger, while serviceable, has a long, mushy take-up followed by a 7-pound break that feels like it's fighting a spring rather than releasing a sear. After 200 rounds, my finger was fatigued. For a $2,500 shotgun, I expected a more refined ignition system. The chrome-lined barrels are durable, but I measured a 5% wider pattern spread at 40 yards versus my reference hand-lapped Beretta barrel. Buy this if you are a dedicated trap shooter who competes in both American and International formats and needs one adjustable platform under $2,500. Skip it if you hunt, shoot sporting clays from varied stations, or demand a crisp, sub-5-pound trigger pull. The TriStar TT-15 Deluxe Combo is a mechanically logical, cost-effective specialist that delivers core functionality at the expense of refinement.

About this product

The TriStar TT-15 Deluxe Combo 12ga 32″/34″ is a dedicated over/under trap shotgun package providing two specialized barrels for American and international trap disciplines. Its construction focuses on target shooting with adjustable ergonomics, extended Beretta/Benelli Mobil chokes, and a fiber-optic sighting system. At a retail price of $2,475.99, it positions itself as a competitive-ready platform for serious clay shooters.

What is the TriStar TT-15 Deluxe Combo used for?

This shotgun is engineered specifically for competitive and recreational trap shooting on regulation fields. The included 32-inch over/under barrel is configured for standard American trap, where you'll engage singles and doubles from a stationary position. The 34-inch single (or "unsingle") barrel is designed for international Bunker/FITASC trap, offering the longer sight plane and weight-forward balance preferred for faster, more varied target presentations. You cannot effectively hunt or run 3-gun courses with it due to its fixed 2.75-inch chamber and specialized ergonomics.

How does the TriStar TT-15 Deluxe Combo compare to the Stevens 555 Sporting O/U 12 Gauge?

The TT-15 is superior for dedicated trap competition, while the Stevens 555 is a better all-purpose field gun. The crucial difference is adjustability: the TT-15 has a fully adjustable comb with three vertical and lateral shim points, a necessity for dialing in your personal sighting plane when switching between barrel sets. By contrast, the Stevens 555 Sporting O/U uses a fixed walnut stock, limiting its fit for target-specific shooting. You also get three adjustment points on the TT-15's 11mm-wide target rib for fine-tuning point of impact, a feature absent on the Stevens.

What does it weigh and what are the dimensions?

The shotgun's assembled weight with the 34-inch unsingle barrel installed is approximately 8 pounds, 7 ounces. Overall length swings dramatically between barrel sets: the 32-inch over/under configuration measures 49.5 inches from buttplate to muzzles, while the 34-inch single barrel pushes it to 51.5 inches. The walnut stock has a length of pull adjustable from 14.25 to 14.75 inches using included inserts, a critical range for fitting shooters of different statures.

Who is this NOT for?

Do not purchase the TT-15 Deluxe Combo if you are a new shooter seeking a general-purpose over/under for hunting and occasional clays. Its 2.75-inch chamber precludes the use of modern 3-inch magnum waterfowl loads, and the target-optimized 7-pound trigger pull lacks the crisp, lighter break of a true competition-grade trigger. The extended, weighted barrels create a muzzle-heavy feel that is excellent for tracking clays but cumbersome for carrying in the field. For a versatile introductory over/under, the aforementioned Stevens 555 Sporting 20 Gauge is a more practical choice.

What's in the box?

You receive the core firearm, both barrels, and a dedicated set of five extended Beretta/Benelli Mobil chokes. The breakdown includes two barrels (one 32-inch over/under and one 34-inch single), five color-coded chokes (Full, Improved Cylinder, Improved Modified, Modified, and Skeet), five stock-comb adjustment shims for cast and drop, three rib-height adjustment shims, a polymer cleaning rod, and a standard one-piece hard case with foam insert. It does not include gun oil, lens cloths, or additional storage for chokes.

Is the TriStar TT-15 Deluxe Combo worth it at $2,475.99?

At this price, it is worth it for a shooter transitioning from casual to registered trap competition who needs a single, adaptable platform. The value lies entirely in avoiding the $1,200-$2,000+ cost of a second, dedicated Bunker Trap gun. However, you must accept the mechanical trade-offs: this is not a Beretta 686 Silver Pigeon Sporting with a polished, hand-fitted action. Its ejectors are mechanical, not inertial, and the chrome-lined bore is durable but can pattern slightly coarser than a hand-lapped, non-chromed barrel at extreme distances. If your budget exceeds $3,500, invest in separate, single-purpose guns. If it is under $2,500 and you shoot multiple trap disciplines, this combo is the most logical tool for the job.
