I was in the gunshop the other day and i noticed they had a binary trigger set for a ruger 10/22. So i bought it. My new magnum research 10/22 i had them put in a timney calvin elite, but i wanted to be able to swap and im having them make me a magnum research charger that i really want the binary trigger for. So i go on ebay and order a new takeoff trigger group to swap the parts into. It shows up today and i put it together and it runs a few strings of rounds and then locks up. I tried with the franklin armory hold open which wont even let me put the trigger group in the action, the stock one will go in but then locks the action up and wont release. I ended up just pulling the bolt hold open lever out of the rifle and it runs perfect then, just bugs me when things dont work correctly. I think i read that one trigger housing wouldnt work with the franklin armory trigger, does anyone have any experience with this?
