Not my Tikka! Fired engaging safety

[Tahoe1305]

I will report back. Still out on the hunt in TN. Back tomorrow and should get to analysis by end of the week.

I have thread locker on all of mine. But torque to 80+ inch pounds and you are probably good.

Yeah, never have put a torque wrench on it but because of these issues I crank it til it feels like the Allen wrench is going to be damaged.

That’s what you guys have always told me to do. Crank on until it feels like it is gonna break

Unfortunately for me, bolts and screws usually break long before I get to that point.

That’s what I’ve done too and I have a have a good hex wrench I feel like I get some solid torque.

I am flying back today. Haven’t taken it apart but trigger outside stock does feel a bit wiggly. I’ll know tomorrow for sure.

I am assuming the allen bolt with the Red paint has become loose, but I wonder why it suddenly loosened up. Glad no one was hurt.

wonder why it suddenly loosened up

Somebody took it apart and didn't properly re-assemble has been the root cause the few times I've seen this happen with any rifle. It happened to one of my mausers once and even though I know it's very solidly assembled now, I don't hunt with it anymore because of it.

I understand why they build them this way but this is my only beef with Tikka. I wish they had used transverse roll pins to retain the trigger mechanism. They don't because the one or two extra features needed on the action for that to work add a disproportionate cost to the action and if nobody puts it together incorrectly, it is a non-issue.

I can't wait till we start getting 3D printed rifle actions. It opens up so so many great possibilities for dealing with these kinds of manufacturing geometry problems.

It didn't suddenly loosen up. The OP stated that the rifle had been in a KRG Bravo Chassis at one point in time. That requires the magazine catch spring to be removed for function with AICS mags. That bolt is used to retain the trigger assembly and the magazine retention spring. It has been removed previously and may not have been torqued to spec when reinstalled.

That's it.

Should I be giving my Tikka-shooting friends a rash of crap about how dangerous their triggers are? I don’t know what’s appropriate given this turn of events. Maybe a Hallmark card asking them to be careful? *chuckle*

Tell em to unload Tikka chambers, drive to river, grab end of barrel with 2 hands, rear back like Barry Bonds and let em fly.

This was a self induced problem and not a factory issue. If you take things apart and reassemble them improperly, the only one to blame is the person who took it apart. *Rolls eyes*

I saw that, but the OP said he has shot the rifle for almost a year with no issues, so it seems odd to me that it would take so long to become an issue if the torque was incorrect to begin with, but weird things do happen.

 

[nm.otter]

Entirely possible if the screw was slowly working its way loose over that time. Movement would not occur until the friction between the trigger body and the action got low enough -- and the curve is not linear.

That’s exactly what happens when screw loosen. It takes time.


Tikka trigger bolt torque has been addressed ad nauseam.

 

[wind gypsy]

I think it's fair for this to be looked at as a negative in some regards as it's clearly prone to people having issues with it if they break loose the way it was set at the factory. I've had a tikka trigger get loose on me after a flight and noticed while shooting with @swavescatter before knowing how hard they had to be cranked down.

Personally i like the simplicity and know to crank the shit out of them. Not everyone is privy though and even Mountain Tactical's trigger install instruction video tells customers to tighten it "just a little more than hand tight" which is crazy. Triggers coming loose like this isn't something that I've heard of happening with 2 pins like in m700 designs.

Man Kansas is boring. Even at 200mph

Two sided coin. Almost anything mechanical has the ability to fail. I think it’s up to users to understand n maintain their tools and machines. It’s not the manufacturers issue if a user doesn’t take the time to learn and maintain what they have. Are some designs less vulnerable than others, sure but it’s not a part failure. It’s not fords issue if you rotate tires and don’t torque the lug nuts down

At the end of the day firearms always seem to carry more dramatic value, I assume bc of the violent tendencies possible when something goes bad, either by the user or mechanical. Firearms are nothing more than a mechanical tool use to start a projectile down a barrel.

A superduty hurling down the interstate out of control bc the owner didn’t torque down the lug nuts losing its tire is pretty violent on impact on.

Check your shit, maintain your shit, if you modify your stuff , check it and maintain it more often

Yeah, never have put a torque wrench on it but because of these issues I crank it til it feels like the Allen wrench is going to be damaged.

I’ve done the same for mine. I feel like ft lbs is a better unit of measurement for how tight I get it.
