Henry Repeating Arms Big Boy X Model H012CX .45 Colt Blue/Black Rifle

The Big Boy X Model H012CX is a lever-action rifle in .45 Colt with a 17.4-inch barrel and an overall length of 36.3 inches. It weighs 7.3 pounds and holds seven rounds in a removable tubular magazine, plus one in the chamber. The black synthetic stock has M-Lok slots, a Picatinny rail and sling mounting points. The 5/8x24 threaded muzzle takes compatible muzzle devices, and fiber optic sights are fitted.

Missouri runs one statewide firearms deer season, and its rules allow centerfire rifles, which covers this .45 Colt lever gun. The November portion runs November 14 to 24, 2026, and the season also has youth and antlerless dates. The receiver is drilled and tapped for a scope, so the rifle can be set up for either range work or the field.
