I own one of the Brocock Bantam Hi Lite in 177 and it shoots great for a short style rifle (bullpup hybrid). It has no problem holding dime sized groups out to 40 and 50 yards. It is light and a small package. It is not regulated but the system is setup such that I get over 100 shots from it before the string starts to drop off. Only varies about +/- 5 FPS

Thx
