Magazine Umarex Hammer

This Umarex Hammer magazine can be loaded with two 12.95 mm (.510) calibre slugs. There are markings on the bottom of the magazine that clearly indicate which side the slugs need to face.

Please note: standard 12.7 mm / .50 airgun slugs are not compatible with the Umarex Hammer. We recommend using .510 airgun slugs.
