hi mate they are a cracking bit of kit, a friend of mine had one for years he regrets he ever sold it some years ago, i have the modern version of it which is the Diana 54 airking basicaly on the same lines as yours but is a semi recoiless springer, to be honest the gun doesn,t flintch when you fire a shot and is superbly accurate (when i,m on form, when i miss i,m to blame not the gun) any way happy shooting my friend buy it you won,t regret it.
