Definitely too loud for back garden shooting without a silencer. As above though adaptors are easily avalable.

Much better value 2nd hand if you can get one. If you ever do start to customise it (easy and addictive), a steel or brass breech is the single best mod to do. Never got on with those horrible pro-block things that clamp on the barrel.

The modding can get out of hand if you aren't careful: Been having a clear out of airgun bits the last few days, and I've found enough 2240/50 bits to make a complete gun
