lol yes I did. The GK grease gun adapter was a hoot. Since the barrel can be seen, sticking the peg in the barrel wasn't going to work (I think that's what that end was for?) nor was sliding the socket over the end of the barrel. my dad cut off the peg and hollowed out the spacer, getting it to slide further on. Trouble is, the barrel thickens here, so it's cracked but still functions as a spacer. how did other's use theirs?
