All FN Red Dot Plates

This thing is great - *much* better than the stock adapter plate from FN that will shear the lugs off if the screws loosen. Which they will do, if you don't put something on there (I use Vibra-Tite VC3), the manufacturer's directions notwithstanding. I did have to shorten the 6-40x12.4mm screws slightly, probably down to ~11.2mm or so.

Flawless construction. Fit perfect mounted a Infatac thermal

My Holly son 507K for my FN502 fit perfectly with the Athena precision Optics plate. The plate is is perfectly engineered and manufactured for the FN502 with my Hollison 507 K mounted.

Great product, if your original plastic plate supplied with your FN 502 breaks this is what you need. I used the Holosun HS407c x2 and it mounted up perfectly. No need to run the rubber o-rings underneath. The pistol optic mount is threaded with 6-40 threads. You will need to shave the screws down as the provided screws were too long I believe were 6-40x12 so the option is to trim them. Maybe provide a shorter version in the next update. No more wiggle or coming loose. This corrected my issue maybe FN should partner with you for their base plates because their plastic version is junk.

It had perfect fitment to the frame , assellas to my Holosun 507k acss Vulcan red dot. The included screws clamped the Holosun tightly onto my Sig 229 Legion pistol. Both the the Athena. plate and provided screws were a significant improvement to tho plastic plate which was warped and could not tighten down to the frame and to the funky screws that stuck up partially into the view o
Thru the red dot. Thank you!
