Uncle Mikes
If you've mounted a low-power scope on a pre-1983 Marlin lever action and find yourself reaching for the hammer with your thumb at an awkward angle, the Uncle Mike's Pre-1983 Marlin Lever Action Hammer Extension solves that problem. This blue-finished hammer extension slips over the hammer spur, giving you a larger, knurled surface to grip when you need to manually cock the rifle. It's a simple mechanical fix for a real-world hunting problem: accessing the hammer cleanly when optics get in the way.
The extension clamps in place using Allen screws, so installation is straightforward—no permanent modifications to your rifle. The knurled texture means your thumb won't slip when you're in the field, whether you're hunting thick brush or working through a course of fire at the range. Because the extension can be mounted right- or left-hand, it works for both southpaws and righties.
This is the kind of no-frills, practical upgrade that makes a difference on rifles that see regular use. If you've got a Marlin lever gun with a scope that's complicating your hammer access, this is worth the modest investment to get your rifle running the way it should.
Yes. This extension is specifically designed to improve hammer access on pre-1983 Marlin lever actions equipped with low-mounted scopes, giving your thumb a larger, knurled surface to grip when you need to cock the rifle manually.
Yes. The hammer extension can be mounted either right- or left-hand, so it works for both right- and left-handed shooters.
No. The extension clamps in place using Allen screws and slips over the hammer spur. It can be removed at any time without affecting the rifle.
