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.

Number 6 will be 6-48 and 8 will be 8-40. Measure diameter to determine its number

i have a bunch of 8-40 if you need just 1 I can send you one

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

What kind of credentials do you have to order from McMaster? I tried last year as an individual, no dice. Probably cost a fair bit of their support time clearing it up.

If you’re in the US you should be able to buy as an individual, outside of US is different due to import export laws and now tariffs.

I dont know if its No.6 or No.8 

It should be a #6-48, but not a standard #6 screw, as gun screws have different threads. You can try reaching out to Tactical Ordnance; they specialize in shotguns and may sell you the screws or tell you exactly what size to buy. 6-48 screws are cheaper on AliExpress than Amazon.

Might be cheaper to buy a replacement rail kit and use those screws than to buy the screws standalone. Dlask has one, and they're clearing them out before they close.
