About DB Gunstocks We are Doz and Sharon and we run this small independent business centred around legal limit air rifles and pistols, based in the beautiful Suffolk market town of Sudbury. We are primarily dealers in secondhand classic era spring piston air rifles and pistols, specializing in BSA Airsporter and Mercury models, and Original/Dianas, Weihrauch break barrels and FWB Sports. We also provide servicing, tuning, modification, refinishing and restoration services for the above, and other guns.
