Weihrauch HW100 Valve Seat/Transfer port

This is a factory replacement valve seat/transfer port for all HW100 models. This is backwards compatible so will fit and work in older models this is also the same part for all power outputs.

You may also require the valve stem/firing valve and valve spring, these are sold as separate parts but are worth replacing at the same time as replacing this part.

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.
