William, will the mount fit the new REM 870 Fieldmaster 20 ga that has the receiver drilled & tapped with 3 real small screws for mounting a red dot or scope? I just got this gun and have the Burris Fastfire III for it and does the mount you have fit these screw holes on the receiver. These holes are much smaller than most screws for mounting a red dot sight. If your mount will accommodate the Burris I will be buying one....Thanks.
