works great
I bought a '06 BOSS SS A-bolt in 1995
its been my primary goto rifle ever since
DON'T USE THE MUZZLE break version, you will get tinnitus and have to buy a suppressor
3/4" groups are easy to tune in, 1/2" groups are possible to with a lot of trial and error
I have swapped the weight for a suppressor and dial that in/out to tune loads
