Not my Tikka! Fired engaging safety

[BLJ]

So basically any time someone puts one in a chassis.

Not necessarily a “chassis”, but my 308 is in an MDT XRS and the factory mag retention spring is still on there.

Not a jab at you, just a clarification.



The one on the bottom

Yes. I don’t think I had a full 133 in lbs.

Like many I remove the OEM springs to put in chassis and whatnot. I’ve always used the “just get it as tight as you can” method. Wasn’t enough I guess in my case. Torque wrench clearly applied more torque in my case.

I wasn’t aware this was a “common” issue. I’m pretty active on the forum and have been for some time (8 years I’m guessing) but first I’ve seen anyway.

If nothing else it’s another thread that may help some folks in similar position. I know for a fact some folks are going to check tension on em.

I had never heard of this issue either, which is surprising given the sheer volume of Tikka info and shooters here.

Well most people buy a firearm and leave it alone. Sure, on this site there may be a larger % of owners who modify, but in the grande scheme, most people leave em alone. I think a % of people within this niche forum doesn’t equate to most owners. Shit, I bet most owners aren’t on this site and even more not even on firearms forums or hunting forums at all.

At least we know

Looks like Fix-It-Sticks only has 100 and 140 in/lbs. Would the 140 be too much? This thread has me wanting to verify my own shit.

No, 140 should be just fine. Still under the rating for the screw. Even if it is off by 10% on the high side, you will still not exceed the screws rating.

20-20 inch pounds for $18.

Remember, you can divide an inch-pound by 12 to get a foot-pound equivalent. 130in/lb is 11ft/lb.

Unfortunately Harbour Freight doesn’t ship to Canada but I was able to find one on Amazon. Thanks guys!

Is anyone using or should you use some sort of thread locker

Thread locker isn't going to hurt anything. I will probably switch all mine over from blue to red and just use a heat gun if I need to take the trigger off.

I feel this is a significant enough concern to warrant overkill (low probability, high risk). Or, as I was told once, when a big brown is trying to eat you, there is no such thing as overkill and fell free to keep shooting once it is on the ground.

Something I wasn't aware of until recently was spraying the screws with Loctite Klean n' Prime before applying the Loctite to cut down the chances it will fail to cure.

I know this isn't really the point of this thread, but since it came up... on the factory mag spring thing... is it a "no longer necessary, but doesn't hurt anything" situation if you leave it in when switching to a chassis?
I'm a bit new to Tikkas, and I left mine alone when I dropped it in a XLR Element. Seems to function without issue.

I'm pretty sure the spring would get in the way on a KRG chassis. Surprised it works with an XLR?

Krg bravo directions do indicate that you remove the spring for t3 install.

I went back through my tikkas to double check that my trigger screws were tight enough. I used 11 ftlbs, and wow, is that a lot more than I was putting them on with. I needed a c-clamp to hold the spring square.

My 223 had a light aftermarket spring in the trigger. It hadn't given me any trouble in a few thousand rounds, so I was going to leave it in there.... but once I tightened the retention bolt to 11, it would release the firing pin on bolt close. So I put a few more turns on the trigger adjustment screw and it would hold.

But, I knew that was asking for trouble, so I spent an hour digging out my factory spring and I reinstalled it. I'll miss how light the trigger was before. But now I can sleep at night knowing all my tikka trigger assemblies are tight as heck and all my springs are factory.

If you're on the fence about taking care of yours, I'd recommend just doing it.
