I have an Air Arms Alpha Proj PCP target pistol with an ambi grip which weighs 900gm without the removable barrel weight and 1.05kgm with it attached. It also has an 11mm rail as an integral part of the barrel. The rail takes a red-dot sight - the one I use at present (when not competing) is a Hawke Sport Dot. At 10metres it is as accurate as my Benelli Kite. I used to live close to Bisley, and the pistol was my first choice in the BFTO competitions. However, I now live in Bournemouth, and the pistol has seen little use since I moved, and is in perfect condition. If you would like more details please pm me.
