Tactical saddle scope mount - Sniper Tactical Saddle Scope Sight Weaver/Picatinny Rail Mounts For Remington 870

Just mounted this on an old Remington 870 Wingmaster. I did first clean burrs from the insides of the mounting holes to assure no extra scratches on the shotgun, and then slid it into place (after removing mounting pins from the 870). The larger mount screw slipped into place without issue. The smaller screw was about .001 over-size, something that was fixed in minutes with some quite fine sand paper. Be careful on that part as too much might cause the threads to slip. After that, mounting was a breeze, and the red dot went into place without issue. While I have not yet fired the weapon, there is no doubt that it will be a solid platform, and that it will maintain it's position. Might have to ultimately put a little thread locker on the screws, but that is all that needs done. A quite excellent product for the price.
