put one on my old 500AT moss 12ga .. love it .. grind to fit type and also cut the stock down to keep the same length of pull .. i just run the open sights on it and now its no longer mule kicking me ..
I've got a Ruger Hawkeye Compact in .308, weighs around 6 lbs with a Nikon scope. Without my Limbsaver it would be downright nasty to sight in and shoot. Part of the concept of a Limbsaver is that it's air chambers not only reduce recoil, but by design reduce muzzle rise. BIG thing with a light rifle.
