Allright, I saw the ATI stocks on the net..and I got one realllly cheap...I couldn't resist.
It's currently sitting on my tracker II 20 gauge slug, and while it looks absolutely ridiculous on a single shot break open gun, I must say that it actually shoulders extremely well and fits me very well, since I'm of smaller than normal stature due to the collapsing stock.
Hasn't broken yet, but if it does ever, I'm not out too much.
The only minus to me is the increased recoil, since the stock is INCREDIBLY light, which makes it nice to tote around the field but not so fun to shoot.
So far, thumbs up to this once I get over the fact that it looks like a mall ninja's skeet gun.
