Questions & Answers
Will this fit the FN 502 tactical? Expert Answer

The FN 502 Tactical has mounting plates compatible with the Trijicon RMR footprint, Vortex Venom footprint, and Shield RMS footprint. The Holosun Holosun HE407K-GR X2 Red Dot Reflex Sight uses a modified Shield RMSc footprint. So the Holosun Holosun HE407K-GR X2 Red Dot Reflex Sight will not fit the FN 502 Tactical.

Will this fit on a HK VP9? If so, what plate number? Expert Answer

The Holosun HE407K-GR X2 Red Dot Reflex Sight uses a modified Shield RMSc footprint. If you have an HK VP9 optics ready model the plate listed below, which is Plate #4 might work. I would contact HK in regards to the plates compatibility with the modified footprint of the Holosun HE407K. If you do not have an optics ready model of the HK VP9 the other link below will take you to a compatible mounting plate. However, the rear lugs of the plate must be removed.

Helpful Positive Review great optic well impressed by tbone, Verified Owner, October 30, 2024
Beautiful that’s all I have to say just beautiful had to make some adjustments to my slide to fit the 43x but other than that it’s pretty solid if you don’t want to shave your slide down you will need to buy a plate for it to fit the 43x

Direct mount for Sig X-Macro. No issues with screws or function. Housing is thick which helps durability however it has a smaller window than some of my other optics. Cleaning the emitter and inner window can be a pain due to the depth but overall I’...
