Fix my gun Looking for a screw
Hello Team,
I have a remington 870 tactical express, I juat noticed one of the screws on the picatinny rail is missing. Can anyone tell me where I can buy a replacment? I saw it on amazon but it also saod frequently returned. I would appreciate any insight, as for size I dont know if its No.6 or No.8 but ill mic it at the shop tomorrow.
it's a standard short rail that came with the rifle.
also wanted, to ask if i Can change it from a slot screw to a torque screw, I saw an option for torque screws online but not sure if anyone has done it.

Flat head counter sink machine screw, slot drive. You’ll need to measure diameter and length using a calliper. Thread pitch can be calculated based on threads per inch. If local places fail order from McMaster-Carr
