The Henry Big Boy .45 Long Colt lever action rifle with 20" barrel and silver finish is a modern take on the classic American rifle—built for hunters, sport shooters, and anyone who appreciates the timeless appeal of lever-action reliability. The .45 Colt cartridge delivers substantial power for hunting medium and large game, while the 10-round capacity and quick-cycling lever mechanism keep you in control when speed matters. With an overall length of 37.5" and a trim 7-pound weight, this rifle balances pointability with substance in the field or at the range.
Henry's industrial hard chrome plating on the barrel and receiver gives the Big Boy a distinctive silver finish that resists corrosion and wear—practical durability that also catches the eye. The stained hardwood furniture and black rubber recoil pad are built to handle years of honest use. A transfer bar safety keeps the gun secure during handling and transport, while the fully adjustable rear sight with diamond insert and brass bead front sight are ready to go straight out of the box for hunting or target work.
If you want to add optics, the receiver is drilled and tapped for scope mounting with the included BB-RSM mount, letting you adapt to your shooting situation. The side gate loading system is intuitive and fast—characteristic Henry engineering that works when you need it. Swivel studs come standard for sling attachment, and the hardwood stock features a durable industrial-grade protective coating that stands up to field conditions.
Whether you're chasing game in dense country, setting steel at distance, or simply enjoying the mechanics of a lever gun, the Big Boy .45 Long Colt is purpose-built to deliver.

The length of pull is 14", measured from the trigger to the rear of the buttpad. This dimension helps determine overall fit; if you're between sizes or have a longer reach, you may want to handle one first or consult Henry's fitting guide.
Yes. The .45 Long Colt is designed for hunting medium and large game, and the Big Boy's 10-round lever-action platform makes it practical for field use where reliability and quick follow-up capability matter.
