CUSTOMER REVIEWS
"I got it because I picked up a Holosun red dot and when I put it on the plate the gin provided I could not zero het sight. It would be at about three inches from the laser when I look through the optic and i maxed out the adjustment. With your plate I’m almost 100 %." -O.S.
"Mounts a Holosun 507k securely. This adapter plate is better than OEM. No worries about the action of the slide shearing off plastic support posts as with the original plates. The rear sights are elevated so that it's easy to co-witness while using an optic. A must-have upgrade for the FN 502." -M.D.

The red dot plate is made perfect and of exceptional quality. It's a bit expensive but worth every penny. It fits my FN502 slide perfectly with zero front back movement even before it is anchored down.The only reson I did not give it 5 stars is that it did not correct my elevation adjustment isse with my Holosun 507k optic. When on the slide, the green dot is above the target. I was under the impression that was machined to correct this - on my gun it did not. It helped a ;ittle but not enough. But overall this plate is much better than the plastic factory plate that came with the FN502.
I talked to Andy this morning I received wrong plate for holosun he507k-gr it was labeled wrong. The customer service is great both Andy and McCall very helpful. Waiting for mailing label to send back plate. Very good workmanship. I may try again at later date.
Fit great on my pistol and my Holosun 407K was nice and snug. A lot better than the factory plastic FN adapter plates. Shipping was quick also! Thank you!
Must have upgrade for FN 502. My optic screws were slowly walking out every time I was shooting the gun with the plastic optic plate. This plate solved the issue. Now screws stay in place and don't get loose. I shot 400 rounds with this plate and optic stayed in place and kept its zero.
Perfect fit on my FN 502. Came with the perfect screws for my red dot as well. FN 502 comes with plastic mounts. And they want you to use their screws, which don't fit inside the dot. So, the dot will move around. This fixed all the dot issues I was having. Worth every penny. Thanks
