The WGP Tickler LP Regulator was standard issue on all high-end Autocockers like the Karnivor. Its lightweight design featured an easy finger-adjustable knob to make fine tuning your timing simple and tool-free. The knob covered the front of the reg body to keep paint out and quick to clean. One of the most desirable Cocker LPRs ever, this is probably your last chance to get an NIB Tickler ever!
