Questions & Answers
Will this mount on a S&W M&P Compact 2.0 Optics Ready Pistol? Expert Answer

To fit the Holosun 407K to a C.O.R.E. model M&P, you would need to use an adapter plate by CHPWS that converts your optic cut to the 407K footprint. With that plate, you can fit this Holosun 407K as well as the Holosun 507K.

by Ethan, Gear Expert, June 10, 2022
Will this fit a Mossberg 940 Pro Tactical? It has factory shade cuts. Expert Answer

The Mossberg 940 Pro Tactical has a receiver mounting slot for red dots that have the Shield RMSc footprint. The Holosun HE507K-GR X2 Red Dot Reflex Sight uses a slightly modified Shield RMSc footprint so it may fit the optics mount on that shotgun but slight modification may be needed to fit properly.

Helpful Positive Review My review of the 507k by Doug, November 4, 2022
I recently purchased the 507k green for my sig 365xl. So far I love the product, the circle dot is very clear and fairly easy to acquire when obtaining a sight picture. The brightness levels are easily adjusted on the optic also.

This HE507k has demonstrated dependability for the short time I’ve owned it. Very easy to adjust for siting in with good button placement. I dinged a star down from 5 because the circle and circle with dot reticles are not very clean/crisp, particula...
