Adding sling mounts to a Remington 870
I have a Remington 870 Express Super Magnum I want to add the mounts for a sling to.
Do I need a new cap with the mount in it? What' I'm talking about is the cap that you remove to remove the barrel and or the plug and all. The one you just screw on. I know it should have a sling mount there but mine has a hole in it. Can you use this or do I need a new one? Then for the rear sling mount I assume I just need to drill into the wood.
I have a gun shop that I'm taking it to for them to put it on but I didn't think to ask if I needed a new cap thing or not.
