Okay, i guess - Sniper Tactical Saddle Scope Sight Weaver/Picatinny Rail Mounts For Remington 870

As stated in other reviews, the screws are to big to fit shotgun receiver, at least the forward hole. Rear screw fit but ended up using the original pin for forward hole. Thought about filing the pin down then it occurred to me the threads would get jacked up and it wouldn't work anyway. Well, what did you expect for $25. This mount will NOT work on the 870 Express with 3.5 inch chamber. The mount partially blocks the ejection port. I have it on a Wingmaster. Mounted a Burris Fast Fire III and put a couple rounds through it. Seems sturdy enough. This will work for me. Now I have a slug gun with scope and will take mount off at end of deer season and put it away until next fall.
