CLC Posted February 17, 2014 Share Posted February 17, 2014 Hey guys, Last week I installed a Burris Fastfire 3 on my glock 17. I used the dovetail mount for glocks that burris makes for the FF3. I read the instructions, and installed it exactly as directed, everything is centered, and on tight(I used loktite as reccomended). I went to sight it in this weekend and here's where my problem started. I started at 10 yards to sight in, then I planned on moving to 25yrds. But, that never happened because I coulnd't even get it on at 10 yards! I maxed out the elevation adjustment on it before I even got withen 8 inches on POI. Granted after a hundred rounds it never moved, the mount stayed tight, and neither the POI or the POA moved a bit... So, it's maxed out, and the POA is about 8 inches above POI. My question to you guys is. Do you know if I messed up something on the install? Or is this mount ment to only provide a zero way further then I was hoping? Thanks for looking, Charlie Link to comment Share on other sites More sharing options...
bigblock455 Posted February 17, 2014 Share Posted February 17, 2014 I run the same set up and mine is dead on. I think I read about someone having a similar problem and they sent it back and it was fixed. Burris has excellent customer service, I suggest calling them.

scottlep Posted February 21, 2014 Share Posted February 21, 2014 I tried to do a FF3 on my G34. The screws included in the Burris Glock mount kit are two different lengths, but barely. I had them reversed. I think the longer ones go in the mount plate to dovetail, then the shorter go from the FF3 through to the mount plate. I noticed the problem when I was trying to tighten the FF3 to the mount plate and I could see the FF3 start to push up in the front from the screws.

Force Posted March 20, 2014 Share Posted March 20, 2014 I'm running the same setup on a G17 slide. POA/POI was within a few inches out of the box at 25. Had no problems adjusting it. Call Burris . Link to comment Share on other sites More sharing options...
Reshoot Posted March 20, 2014 Share Posted March 20, 2014 Yep, Burris will take good care of you! They replaced my Fastfire 4 times in one year. Actually, it was 2 Fastfires, and they replaced each of them twice that year. Then, I wised up and installed a frame mount, and a DeltaPoint Good luck keeping a slide mounted Fastfire working!
