Description
The Truglo TG112 gives your lever gun the sight picture it deserves. It replaces the plain factory front and rear with a CNC-machined fiber optic set that pulls light straight into the fibers, so you get three glowing reference dots instead of a dark blade you have to squint at. The front runs a red fiber at .060 inch diameter with a taller .450 inch height, and the rear carries two green fibers at .035 inch. That red-into-green contrast is what makes lining up the shot quick and intuitive, especially in the flat light you get under a range roof or in early morning timber.
What the TG112 Fits
This set is dialed in for the classics. It drops onto the Winchester 94, the Henry Golden Boy .22LR, Marlin lever-action guide rifles with a front ramp, and the Henry Big Boy .44 Mag. One thing worth knowing up front: it's built for standard rifle barrels with a front ramp, not carbine barrels, so check your muzzle setup before ordering.
Getting the TG112 Zeroed
The rear sight gives you full windage and elevation adjustment, so you can chase your point of impact around and lock in a real zero rather than living with whatever the factory sight handed you. The taller .450 inch front is there to work with that adjustment range and give you the right sight-picture geometry once everything is dialed.
Why Folks Upgrade to the TG112
A lot of the appeal here comes down to aging eyes and tough lighting. Focusing on a bare front blade gets harder over the years, and a plain sight practically disappears against a black bullseye. The fiber dots stay visible against dark targets even when the overhead light isn't strong, which is the exact scenario that sends people looking for a fiber optic swap in the first place. Machined construction and a black finish keep it looking like it belongs on a wood-and-steel lever gun rather than a bolt-on afterthought.

Frequently Asked Questions
What rifles does the Truglo TG112 sight set fit?
It's designed to replace the factory sights on the Winchester 94, Henry Golden Boy .22LR, Marlin lever-action guide rifles, and the Henry Big Boy .44 Mag. The fit relies on a standard rifle barrel with a front ramp. It is not intended for carbine barrels, so confirm your barrel configuration before ordering.
Does the TG112 use tritium or fiber optic dots?
This is a fiber optic 3-dot set, not a tritium setup. The fibers gather ambient light to glow, giving you a red dot up front and two green dots at the rear. That means they light up in daylight and normal indoor lighting but won't glow in full darkness the way tritium would.
Can I install the Truglo TG112 myself without a gunsmith?
For most owners it's a straightforward drop-in replacement for the existing factory sights, no gunsmithing required. You'll typically drift the old sights out and the new ones in using the dovetails. Take your time, support the barrel properly, and go slow when tapping the sights into place.
Why upgrade to the TG112 over standard iron sights?
The big draw is a brighter, faster sight picture, which is a real help if focusing on a plain black front blade has gotten harder over the years. The fiber dots stay visible against dark bullseye targets even when overhead lighting is dim. On top of that, the adjustable rear lets you fine-tune your zero instead of settling for the factory point of impact.
