I removed the Timney 510 trigger out of my 700 today to put it in another rifle. The trigger worked fine in the first rifle, but this new rifle it won't hold the firing pin back when I cycle the bolt. Both rifles are Remington 700's. Does anyone know how to adjust these triggers? I can't find anything online, and really don't want to send it back to Timney and pay them to fix it. I've adjusted my factory rem triggers before with great success, so I know I can do it safely.
