Weihrauch HW100 Adjustable Hammer assembly

This is the factory HW100 Hammer assembly that has had the antitamper removed and a slot cut in the adjuster to make adjusting the hammer easier.

Please note: Before you adjust the hammer you will need to remove the the small grub screw from outer part of the rear hammer assembly, once you have made your adjustment this must be re-fitted. Do not over tighten this grub screw as this can make future adjustments harder.

When fitting this part or working on any air rifle we do advise that the user has access to a chronograph, as installing this part may alter the output of your air rifle.
