The Super 91 W Series is marked at the barrel with maker, model, caliber, and "Black Powder Only," reflecting production in Roosevelt, Utah. Its 24-inch round blued steel barrel is crowned and paired with an under-barrel ramrod for field loading convenience. The design emphasizes fast-twist, shallow-groove rifling intended for slip-fit conical bullets, with factory literature referencing bullets designed for 1:24 or faster twist rates.
The inline action uses an external rear striker and a 209 shotshell primer ignition with a recessed primer-pocket breech plug. Safety is addressed with a primary safety lever at the rear of the receiver and a secondary safety achieved by rotating the cocking piece.
Sighting equipment includes a ramped front sight and a Williams-branded adjustable rear sight for clear indexing. The steel receiver is drilled and tapped and fitted with scope mounting hardware, allowing the buyer to add compatible optics if desired.
The black synthetic stock features textured, molded checkering for grip stability and a Bell & Carlson recoil pad. Sling swivel studs are installed, and the length of pull measures 14.5 inches, offering a steady shoulder fit. Overall capacity is single-shot as expected for a muzzleloader.
