Mount a scope on your Henry Big Boy and you quickly run into one annoyance: the optic sits right where your thumb wants to be when it's time to cock or lower the hammer. Carlson's built this hammer expander to fix exactly that. It bolts onto the existing hammer spur and pushes the contact point out to the side, giving you clear, positive thumb access whether you're running glass or shooting irons.
The design is ambidextrous, so lefties and righties both get an easy grab at the hammer no matter how they run the gun. Carlson's went with a T-shaped offset that gives your thumb something real to push against, and the knurled body means no slipping even with cold or gloved hands. It's balanced and lightweight too, which helps keep wear even on the trigger and sear surfaces over the long haul. The unit measures .375 inches in diameter and 1.5 inches long, machined from aluminum and finished in a tough black hard anodize that holds up in the field.
This one is made specifically for Henry Big Boy centerfire rifles built after 2010, so double-check your model before ordering. Installation is straightforward and doesn't call for any permanent changes to the rifle. Slip it over the hammer spur, snug it down, and confirm everything cycles right before you head to the range. Folks who've added extensions like this to scoped lever guns consistently point out how much easier the hammer is to reach and how it doesn't mess with trigger pull or accuracy.
Carlson's makes this piece in the USA and stands behind it with a lifetime warranty. For a small upgrade, it makes a real difference in how your Big Boy handles, especially if you hunt with optics or just want more leverage and control at the hammer.
It's made specifically for Henry Big Boy centerfire rifles built after 2010. It will not fit first-generation H006 Big Boys made up to 06/24/08 and ending at serial number BB0030015, so check your rifle's age before ordering. If you have a rimfire Henry like the Golden Boy, you'll want the separate Carlson's rimfire version instead.
It's most useful when a scope crowds out your thumb access to the hammer, but plenty of folks like it on iron-sighted guns too. The extra offset and knurled surface give you more purchase and leverage on the hammer, which makes cocking and lowering feel more positive. Cold-weather and gloved shooting is where a lot of people appreciate it the most.
Not at all. It comes with an installation tool and instructions, and it slips over your existing hammer spur and tightens down with no permanent modifications to the rifle. Make sure the rifle is unloaded, snug it up, and verify the action cycles correctly before live fire.
No. This is a hammer spur extension, not a trigger part, so it doesn't touch how the trigger breaks or how the rifle groups. Being balanced and lightweight, it also helps keep wear even across the trigger and sear surfaces over time.
