BSA Super 10 Bullbarrel Carbine in .22

Factory specs: 7.7 Lbs (or 3.5 Kg ), sans optics.  33.5 inches (85cm) overall length.  10 shot magazine.  20ft-lbs power (around 750 fps) and 45 shots per fill.  200cc reservoir.

Reality specs: Weight, length, & magazine capacity concur.  Power is closer to 16 ft-lbs (718 fps with 14.3gr Crosman Premiers) with mid-weight pellets and 40 shots per fill until it falls off the regulator.  Not quite as quiet or powerful as I had expected, but still a very compelling shooter.  Trigger is excellent.

Modified and added a new bolt handle:
