Tokyo Marui Hi-Capa Gasblowback

A used Tokyo Marui Hi-Capa 5.1, used only once in a airsoft match and only a few times recreationally but other than that its been sitting around without use. I purchased a 3 years ago new, it probably needs some maintaince (oil/greasing intenals) as i havent gotten round to do it. It works perfectly. Plz note all mags have started to leak unfortunetly so it would need mags which are common or repair. Contact:07414938732
