Trigger issue

[yoteslayer]

Sounds like to me that the trigger is releasing I think what's going on is when you torque the screws down it's bending the action a little and the cocking peace doesn't have enough clearance to slip past the sear so take a stone or file and take a little off the peace that protrudes out off the bottom of the shroud or bolt plug if you call it that so it has a little more clearance it should fix your problem you can take a pretty good amount off with out ruining it so just do a little and try it until it works let me know if this fixes it good luck

Hello all,
I am trying to do some investigating into what is happening with my trigger. I bought a Calvin Elite 2 Stage from another guy and at first glance it looks great. In fact, even when it is just on the barreled action it functions fantastic. BUT, when I put the barreled action in the stock and torque down my bottom metal the trigger begins to malfunction. When I pull it, it won't release the firing pin inside my bolt assembly until I move the bolt handle. Then, the firing pin will drop. I assume it gets bound up somewhere within the stock or with the bottom metal, but where would the pressure have to be on the trigger to cause this?
Thanks in advance for the input,
John

A question for you; Do you use a torque wrench while performing this function? I like my lug screw @ 35-38 inch lbs. & 28 on the tang screw. The cause usually a rigid stock that will flex the action just a few .001's.... this will cause the problem.
I have had this issue before. First, start by tightening the lug screw, check trigger. It shouldn't have been affected yet. Secondly, start tightening the tang screw a little at a time each time checking the trigger for its release. at some point the trigger will fail. This is most likely where you'll find the problem. Remedies could be resolving with torque adjustment, resolving "action to stock contact" or re-tuning the trigger.

peace

Yes, I do use a torque wrench. And that's a good idea! Thanks!

If you find the trigger is binding on the bottom metal, you might try using a washer between the stock and recoil lug on your forward action bolt.

This is exactly the wrong way to fix a trigger problem if it is bedding related.. Fix the bedding! Don't go 'whittling' on the cocking piece!

 

[yoteslayer]

Shortgrass is correct you should fix the bedding first but if that doesn't fix it timney will have you do exactly as I mentioned you have to do this on ruger m 77 triggers all the time and if you look at timneys trouble shooting for there triggers this is the solution they recommend

Glad to see this thread. I'm having some issues with a Timney 510 in a 700 milspec 5R. Issue with bolt release, but I won't hijack thread. Solution seems to be the same once proper adjustment ruled out. Watching.

No worries ask any questions you have! By the way, your trigger pin isn't contacting the inside of your bolt release is it?

No, I've pulled it and was very careful putting it back together. It just seems to stick once the action screws are torqued.

Yup, welcome to the conundrum. I think I know how to fix mine. Just have to take some time and mentally prepare to start removing stuff that can't be put back on! Haha

The bolt release on a Timney is held in by a small Allen head screw. These can contact the stock inlet and just takes a few minutes with a file or dremel to clearance the trigger inletting.
Another very common problem with the Timney is the adjustment screws/nuts on the front of the trigger housing protrude much more than a factory trigger. Just need to clearance the inlet for that also.

Thanks for the info! I'll be checking clearances in areas I didn't think to before.

Also check the bottom metal. Most the time the inlet for the trigger needs some attention for the Timney to fit.
The little tab on the top of the bolt release that rides in the notch in the actual bolt release usually needs some tweaking/bending to fit better also.

Time for me to make a file with all the good information I keep getting on this site!
