As a gunsmith, for powder burners mind you, it amazes me the customers that will bring me things to repair that they can easily do themselves, even with zero knowledge. Sometimes I even tell them so and inform them that they would be wasting their money to have me do it but they still insist. Had a guy that told me he was uncomfortable putting new grips on a pistol (it was 2 screws).I know this doesn't help the folks that already sent their gun to FX, but I imagine that alot of those repairs fall in the same category. Seals are a big culprit in airgun malfunctions and can easily be measured, ordered and replaced.
