This Mini Thirty is an early 189-series example that aligns with late-1980s production and carries the Southport, Connecticut rollmark. It is in the standard configuration with an 18.5-inch barrel and a plain crowned muzzle, with no flash suppressor or bayonet lug.
The action uses a short-stroke gas piston with a Garand/M14-style rotating bolt. A 4-screw clamping gas block is fitted, consistent with this period of production.
Sighting is via iron sights: a wing-protected front post and an adjustable rear aperture with a windage drum marked "R." The upper handguard is ventilated polymer with rectangular ports to aid cooling.
Construction details include a blued steel barrel, a matte gray-finished steel receiver, a hardwood straight-comb stock with a smooth, uncheckered finish, and factory sling swivels. The length of pull is 12.5 inches, and the stated capacity is 10+1 in 7.62x39.
