Demonstration of the Pump Assist
After all the technical stuff on the other pages, this is the fun
part. The video clip below (15 seconds) demonstrates the
action of the Pump Assist Mod on a Benjamin 392 with .22
Crosman Premier Lights. I am an average build, 5' 10" guy,
but in this clip I pump a Benjamin airgun to full power (8
pumps) in less than 8 seconds without breaking a sweat.
Notice I'm holding the rifle by the pistol grip. Try that with
your standard Benjamin. This is possible because I designed
the dynamics of the Pump Assist mechanism to operate like a
pendulum. View the video to see the results. At the end of
the clip I blow a hole through a 3/4" plank of pine to
demonstrate the power is the same as a factory Benjamin. If
you look carefully you can see the wood chips fly. Enjoy!
