You'll have to put a variation in for one in the first instance, This is normally not an issue, was when I first applied, Once variation back you will have to get rifle screw cut if not already done, then put through proof house and finally buy the moderator
I have a T8 fitted to my Tikka T3 Stainless Lite in 222 which works very well, Slightly Barrel heavy though in balance
Hope all goes well
