Gamo GX-250 .177

Gamo GX250, very good condition, probably had less than 2 tins of pellets through it. Comes with mounts a 3-9 x 40 BSA scope, high pressure stirrup pump, 2 x mags, fill adaptor, bi-pod and hard case. Complete kit. Ideally looking to sell it for cash but may consider a trade for an Air Arms TX200 underlever in .177.
