They sure give you a wide variety of guns to choose from. I'm happy to here my videos have had some influence on some airguners. Others have said the same.

Professor,

Another well done and informative video. Was trying to decide which pistol I preferred, but each one was impressive, on close up view. The precision ammo accuracy was a shock, I had no idea what a difference it would make. The barrel extension was an impressive mod, the gun looked so natural with it, I'd bet without being told otherwise, folks would think it's a factory original. Thanks for another look back at our air gun past.
