Timney trigger install problem

[caseharvester]

I have installed a Timney trigger in my Remington 700 action and it works just fine when the barreled action is not in the stock. I put the barreled action in the stock without the mag box(aftermarket factory 700bottom metal from midway) and everything works fine.

My problem is when I install the mag box,test fire and cycle the bolt the safety Will not move and when I close the bolt the firing pin will fire. I have taken the barreled action and stock apart several times before I figured out it would work without the mag box. I can't seem to see anything that's hitting or rubbing. Hope it's something stupid but I can't seem to figure it out. Thanks

There is probably pressure on the trigger from the different bottom metal. I had this exact same thing happen with a timney trigger and that was the issue

I had the same issue. The stock inletting was interfering. Seems the Timney is a bit thicker than the factory.

The trigger is wider and likely making contact with the bottom metal in the trigger opening. Also the trigger body is wider and the stock may need some clearance also.
