Torque Specs: Tikka T3 Gen2 Performance Series Picatinny Rail
Just got this in the mail from Mountain Tactical. Seems like a great base and am looking forward to using it. Instructions didn't come with torque specs–a wrench, yes, but not torque requirements. Does anyone know how tight to make the screws? Thanks.

I use 25in-lbs (max) with a drip of Blue Loctite. Zero issues on 5 rifles mounting MT & EGW rails….
This is the spec Mountain Tactical recommends. -
Dog is correct, you don't need to go hard on on the screws, the pinned mountain tac rails only need to be locktighted a bit. the integral pin takes all the stress. so all the base issues are fixed.
now the rings need addressing. I used to think high quality rings were good to go. I now know that that is not the case. you need to lap ALL Rings (except some that have polymer inserts).
I have several DNZ Freedom Reaper one piece rings that are claimed to be true since they are machined from a single block of metal. While I like them and will use them in future, they need to be lapped.
I lapped a recent set of Freedom Reaper Rings and found there was a significant amount of non-contact with the lapping bar. This means that the rings were not contacting the scope body fully and while you may never see a problem, you can see a potential problem. unless 80%+ of the ring engages the scope body, you are asking for damage to the scope surface on a hard recoiling rifle. Lap those rings and you will never have a problem. That said, if the rings are steel you might have to deal with corrosion caused by lapping. oil em and occasionally check em.

There it is.
And I lap every set of rings that go on my scopes. 75 to 80 percent on my hunting rifles, 100% on my competition rifles. Even NF rings need it.

Hi for me if you need to lap the rings there not made correctly, don't know anybody that's needed to lap rings from Tier one over here in England,

Sorry Larkin, I'm gonna throw the bullship flag on that one.
Take your Tier One rings, install them on your favorite action, and I'll put a lapping bar in them and start lapping…and show you how uneven they mate up.
Doesn't matter if it's the finish applied, the rings (if a 1 piece), the rings if two piece, or perfect rings fitting in screw holes that aren't aligned perfectly front to back when drilled into the top of the reciever…ALL rings need to be lapped to achieve perfect fit with the scope.

Lol don't be sorry we all have different opinions that's what makes this site so good , also Teir one's rings and one piece unimount are made out of one sold billet all machining is done completely in one hit then split so no alignment issues
