posted about a month ago regarding my mk|| r10 in 177. Sent off for a service new rings and seals got the gun back started using it again over the last 2 weeks and low and behold last night put 40 shots though it to find the tank was empty ? lucky had the old trusted s510 ? in the van so not a wasted journey this time but seriously pissed off with this r10 I had the mk| many moons ago and that was a major let down thinking about trading the mk|| in when the problem is fix whatever that maybe ? ? and will not be going back to bsa for a long time ??
