Swivel Magazine Cap for Remington 870

I actually have a remington one.

I bought one a long time ago for my 870, it's an actual remington brand one. It was pretty cheap, under $10 I think. Unless it's built really cheap, it should be OK.

I bought a different brand, Allen I think, but it looks identical to the Uncle Mikes. I have had no issues and like being able to remove the sling quickly with the detach feature. I would pass on the shell holding sling. You will find they don't really serve a purpose other than being in your way and causing the gun to sway around with all that weight swinging under it. Good luck.

Ok so I installed the Uncle Mikes to my 870 and fits perfectly, it is made pretty sturdy and I see no difference in quality between the factory and Uncle Mikes.

This is the one I've got on my 870, only mine's black. Love it.
"Guaranteed forever." (We'll see...)

I`ve got an Uncle Mikes. You will be fine. I like the sling too. Might have to get one of those.

Just bought a new 1187 sportsman, and it was already on it. Apparently remington is installing them on certain shotguns

Yep - I have an Uncle Mikes on my Winchester pump. I've had it for years... certainly tough enough.

As for shells - just get a butt stock shell holder. You can't beat the simplicity. Good luck!
