I have a 180 that has an original stock thats a little beat up. I wanted a nicer stock but wanted to leave the original alone so last week I cut down a QB78 stock to fit. Left a little more meat than the original stock, and with the butt pad and little longer forearm it added around 2 3/4 crucial inches for a more 'adult' feel. You can see it in the 2nd pic that I had to drill a new hole for the locating stud and the old hole is a bit unsightly but I'm not a perfectionist so it doesn't bother me. White butt spacer did not come out as clean as I hoped but again, Im satisfied with it. It was one of the old orange painted, gross looking QB stocks that someone gave me last year because they were gonna just throw it away. wood grain is decent I would say.
One things I really like about this gun is it shoots the 22 gamo round balls just as accurate as can be at high and low power. It really is a hole on hole gun, I just cant get enough of it. Also it has the all brass valve.
Anyway hope you like it too!
