Another unique design to the Tech Force product line of fine air guns. The TF66 is a tactical air gun that fits in its own briefcase (included)...it assembles in seconds by simply attaching the barrel group to the receiver with a hand turned knurled nut...and it shootes either BB's or special pellets from a ten-round magazine. Regular .177 pellets can be fired in single shot mode. The TF66 is equipped with a high powered scope which is attached to the barrel so it retains its superb preset accuracy. To use the TF66 as a repeater, just cock the piston spring-powered air gun with the side lever, drop in a loaded clip of lead BBs or special pellets, and fire up to ten rounds by simply cocking the rifle and pulling the trigger. Pellets can achieve a velocity of 750 FPS, plus outstanding accuracy. Use only lead BB's (not steel) in this repeater; ask for information on special pellets for use in the magazine when using the TF66 as a repeater.
