Description
Anyone who has put a scope on a Winchester 94/22 knows the problem right away: the hammer sits low and gets crowded out by the optic, making it a pain to cock or ease down. This little extension from Uncle Mike's fixes that. It slips over the factory hammer and gives you a taller, wider spur to work with, so your thumb has something to grab instead of fighting for room under the scope tube.
The build is straightforward and dependable. It's made from blued steel with a knurled surface, so even with cold or gloved hands you get a positive grip when you're cocking or letting the hammer down. The blued finish keeps it looking right at home on a lever gun and adds a bit of corrosion resistance. It runs about 4.9 inches in overall packaged length and weighs next to nothing, so it won't throw off the balance or feel of your rifle.
Why the Hammer Extension Makes a Scoped 94/22 Easier to Run
The whole point here is leverage and access. Instead of reaching under the scope, the extension lets you get at the hammer from the side for more positive control. Hunters who keep the hammer down while carrying a chambered round tend to appreciate how much easier it makes both cocking and safely decocking. It's a small upgrade that pays off every time you handle the gun.
Fitment and Setup for the Uncle Mike's Winchester 94/22 Extension
This one is made specifically for the Winchester 94/22 and 94/22M rimfire rifles, not the centerfire Model 94. It mounts on either the right or left side, so lefties are covered. Installation is quick with the included Allen wrench, and a smart tip from folks who've owned one: put a dab of thread locker on the set screw so it stays put through years of use.

Frequently Asked Questions
Will this hammer extension fit a standard Winchester Model 94?
No, this version is made specifically for the rimfire Winchester 94/22 and 94/22M. The centerfire Model 94 and Big Bore 94 use a different Uncle Mike's extension, so make sure you're matching the part to your exact rifle before ordering.
How does the extension attach to the hammer?
It slips over your existing hammer and locks down with a set screw, which you tighten using the included Allen wrench. Many owners recommend adding a small dab of thread locker to the set screw so it stays snug over time and repeated use.
Does it work for left-handed shooters?
Yes. The extension is ambidextrous and can be positioned for either the right or left side, so it works well no matter which hand you run the gun with.
Why would I want a hammer extension on my 94/22?
Once you mount a scope, the hammer can be tough to reach and cock from underneath. This extension gives you a bigger, knurled spur you can access from the side, making it easier to cock or safely lower the hammer with better control.
