I nee a break.

hard to see in this pic, but I went with the badger fte micro. I wanted something a bit more compact when I had my barrel cut to 18". It does a pretty good job, the 308 kicks a little less than a 243 now.

If you could measure the muzzle diameter that could help us point you in the right direction. If the muzzle is very narrow you may have to go with a micro brake and the standard 5/8" x 24 TPI threads seen on most .308cal rifles may not work if there is not a large enough OD to accomidate it. You may have to go with a 9/16" x 32 TPI. It is smaller in OD obviously and the finer threads do not cut as deep as the 24TPI providing a little more wiggle room. You would have to call and special order / specify this thread.

On a hunting rig you may take a look at the VIAS Micro Brake. It can be blended to the same contour as the barrel (provided the barrel OD is large enough) for a seemless fit and finish. Vais Arms Inc.
 
It's a tikka t3 tactical it is threaded



I just never gave any thought to how my wife would handle it she is 5"4" 110 lbs so it really beats her shoulder up. I don't care about looks I just it just needs to be made manageable.
her favorite rifle is her ar15 and she has no problem with that recoil. I had a savage fcp-k and the break on that made the recoil much more manageable for her but I sold that in order to buy this I have read that the factory threading on the tikka is different than most other rifles is this the case?
 
A LimbSaver recoil pad makes a huge difference as the Tikka factory pads SUCK! This won't replace a brake but it helps either way. I'd love to have a brake on my Tikka Varmint but I would need to have my barrel threaded first.
 
I would probably go with the tank brake

I had an armalite AR30 brake on a custom 300WM and it actually produced what I felt was some negative recoil. The gun would actually move a bit forward with each shot
I could shoot all day and have zero fatigue. On the flip side it is very loud and the concussion from it was a bitch
