Built in Rochester, New Hampshire before the Smith & Wesson acquisition, this full-size .50 caliber Omega features the sealed Speed-Breech system, 209 primer ignition, and crisp internal striker action that helped define the model’s reliability and quick follow-up shot readiness.

This Omega variant stands out for its laminated thumbhole stock finished in a gray/green swirl that offers a 14.5" length of pull, a Monte Carlo comb, and solid wrist support for steady off-hand shooting.
The 28" 416 stainless barrel carries a 1:28" right-hand twist, a rate tailored for modern saboted projectiles and heavy conical bullets, helping shooters achieve consistent accuracy at extended muzzleloader ranges.
An internal striker-fired inline action combines with Thompson/Center’s sealed Speed-Breech system to streamline cleanup and prevent fouling in the action area. The muzzleloader loads from the front and accepts standard 209 shotgun primers for reliable ignition.
Bright fiber-optic open sights—a high-visibility orange front bead and fully adjustable green two-dot rear—provide fast target acquisition, while the receiver is drilled and tapped to accept scope bases if preferred.
The matte stainless finish on both barrel and receiver resists rust in harsh weather, making this USA-made Omega a durable choice for hunters or black-powder enthusiasts seeking a robust, discontinued model.
