One thing we see a lot on older airguns, is the use of leather seals.
While there is something to say for these classic designs, those seals do need maintenance. Which is often neglected.
When these leather seals dry out, they crumble to pieces.

Luckily, Weihrauch has developed an adapter to fit modern, synthetic seals to olders pistons and barrels!
So no matter the age, your Weihrauch can always be brought back to life!
