The Omega X7 is an inline, single-shot muzzleloader with an external hammer and an under-lever/hinged trigger-guard that operates the sealed breech. It is chambered in .50 caliber and uses 209 shotshell primers for ignition, aligning with the Omega-series design from the 2000s.
The 24-inch blued steel barrel carries a 1:28 right-hand twist and incorporates the Quick Load Accurizor (QLA) muzzle system to aid loading. The Speed Breech 90-degree removable breech plug is an Omega-series feature designed for straightforward access to the breech.
The laminated hardwood stock has a brown/amber finish with a pistol-grip profile and sling swivel studs. This rifle is fitted with a LimbSaver recoil pad and bears the Thompson/Center medallion in the buttstock.
Sighting is set up with iron sights: a green fiber-optic front blade and a Williams receiver-mounted aperture (peep) rear sight. The steel receiver and barrel wear a blued finish, and the rifle is marked Thompson/Center Arms, Rochester, New Hampshire.
