Carlson’s Hammer Extension (part no. 00114) makes cocking a Henry Golden Boy rimfire rifle faster and more comfortable for both right- and left-hand shooters, especially when a scope sits over the action. The knurled aluminum body slips over the factory hammer and adds real leverage without permanently altering the rifle.
