Gamo may not be good to sell parts but I yet to have them turn me down for warentee . Just tell them the deal they say send it I say ok they send me a package slip to put on the box and I drop it off at ups/ fedx drop site. Guns back in 2 weeks or less.If nothing else gamo is great in that so far. Near no question asked warrantee and pay all shipping.
Most likely the CF-30 was dropped when Gamo acquired BSA and turned their underlever into the CFX.
