I recently purchased a Trigger Tech Trigger for an early 70s model 700 Remington 270 cal. Everything went well as far as installing. I tested everything before replacing the stock and all was perfect. I installed the the front action screw and the rear action screw. When I installed the front trigger guard screw with the rifle cocked and safety off the rifle fires. It is repeatable and all works well when this screw is removed. I cannot see nor figure out why this would be happening. Any help is appreciated. Thank you-
