For those that are interested, I managed to put a Limbsaver pad #10824 for a Ruger American Compact on the Tikka compact stock. Of note, it was not a direct "plug and play" - took a little bit of work but turned out really well. Thanks to
@XR357 !
As mentioned by
@XR357 the hole patterns on the Tikka compact stock and the limbsaver Ruger American pad do not align. (As a tip, the spacing between the holes on the Tikka compact stock is 80mm. The spacing on the Ruger American pad is different.)
To make this work, what I did was:
1. Order the Ruger compact limbsaver pad from limbsaver.
2. Remove the four plastic nubs on the back of the new recoil pad.
3. Probably not required, but I filled in the existing/factory/stock holes on the Ruger limbsaver pad with JB weld. I used the same technique as one would use to repair a hole in drywall. (Pushed a piece of cardboard down through the hole, and tied to a sewing string held taught, to keep the JB weld from going everywhere or down into the recoil pad too much.) Again, probably overkill, but it worked.
4. I re-drilled the top hole. (Used a 7/32" drill bit.). This went fairly smoothly as plenty of clearance existed from the factory / stock hole to the new hole required to make everything fit. [When I say 'top' hole I am referring to the hole near the top of the recoil pad, if one were to hold it as if it was mounted on the rifle.] As mentioned above, one has to be careful drilling as the drill bit poke through the hard plastic outer shell, then will grab onto the rubber recoil pad and catch. (Kind of like drilling through drywall and into the insulation behind the wall.)
5. I re-drilled the bottom hole. This is where things got a little messy. Because the two holes ended up being so close to one another, the JB weld ended up pulling out. Ended up with kind of a warbled out hole, but it was not that big of a deal.
6. Tightened the top screw through the limbsaver recoil pad and into the stock. This screw was at a bit of an angle, just went slow and made sure to align everything.
7. Tightened the bottom screw.
Note, I did not drill any holes into the soft side of the recoil pad. Only the hard plastic side that butts directly up to the rifle stock.
As you can see from the pictures, the final product turned out alright.
I prefer the limbsaver Airtech precision fit recoil pads over the stock Tikka recoil pads.
This DIY ends up with a limbsaver pad on a compact Tikka stock.
