Can anyone help with the following please

We have two morini 162c target pistols at our club,one now has a leeky cylinder

Therefore can anyone point us in the right direction of a u.k agent or agents,that undertake repairs on the these models please

We do not wish to try and repair ourselfs,only with 300 bar,high power air,we need to be safe

Thanks Les (S.O.S R & P Club)
