The Burris FF3 will not sit flush on the Doctor adapter plate. The front of the FF3 curves out a bit and hits the slide's cutout. It looks like you could file the front of the FF3 to let it drop down onto the plate, but I opted to just use a different sight. Other than that, it is a well made adapter plate.
This plate is solid and well built, fairly affordable, and Springfield shipped it out pretty quick. I got it for an MPS but once mounted it raised the MPS just enough to lose co-witness with the OEM Echelon iron sites. I knew this could happen but I couldn’t find any info with how new the Echelon is. So, if you want this setup and keep your irons, you’ll have to order higher sights to work. I just wish Springfield would’ve noted that in the description of this plate on their website.
This comes in handy if you have an optic that either has the Arco/Doctor footprint.
