Build your own winger or convert different style winger with this bolt on trigger mechanism.  Over a year in testing and development to arrive at this solid locking and very safe design that pops a 209 primer.  This mechanism is used on all the wingers. Lifetime warrantee. Patent Pending. Watch video where this trigger when locked, picked up the back end of my Toyota. This is by far the strongest and safest winger trigger out there.
