np. have actually had a few inquire. to all reading i believe i have two paks but were not in the place i thought..I will need to dig a bit deeper. Im pretty certain i did not toss out. my garage is a wood shop, metal shop, gunsmith shop, bar/dart lounge, auto shop..etc.Might hit you up once mine arrives and I see for myself how it attaches. They wanted like 15 bucks for a nut! I could machine one out of titanium for less than that!
