## Overview

The Uncle Mike's Hammer Extension is a precision-engineered accessory designed to enhance the cocking leverage of Marlin lever action rifles made between 1957 and 1982. Featuring a durable blued steel build and a knurled grip surface, it fits both right and left side hammers and accommodates low-mount scopes.

## Description

Uncle Mike's Hammer Extensions slip over hard-to-reach or hard-to-cock hammers for extra leverage. A must for scoped guns with external hammers.

Review: Fits good - I had to file one little side bur that the machine missed but no big deal it took like two mins but fits perfect now! It's worth it my finger wouldn't fit under my scope with my gloves on to pull my hammer back on my marlin 3030 so I bought this and it's perfect way easier to cock back during rifle season!
