Anyone mount a FF3 on thiers? If so which screws did you use? The screws that came with the gun (screws and mounting plates look like they are the perfect length but they seem snug going into the two screw holes that match for the ff3. The holes that match up are the same holes for the factory gap cover. I didnt wanna force them in and strip anything should they be ever so slightly different and maybe im just not seeing it.

I had one on mine for a while ,I ended up finding longer screws locally. One of the included sets matched the threads but weren't quite long enough for enough thread engagement for my liking. It's been a while but I either found the thread specs from Google searching or the factory manual.

I was able to get a set of the included screws to work. It was short lived though as I couldn't get the ff3 to adjust enough for proper POI for elevation. It was WAY off.

I got a few 5-32 x 1/2 screws. they work perfect with the FF3.
they are just a bit longer
