Questions & Answers
Is the Holosun name/logo, and model/serial number, painted on, or is it a decal? I've been waiting months for a HE508T-GR-X2, because it's all black. Expert Answer

Yes they are painted on there on the sides of the red dots.

Will this optic fit He'll Cat Expert Answer

To mount the Holosun HE507K-GR X2 1x Green Dot Reflex Sight to a Springfield Hellcat OSP, you will need to use the C&H Precision Weapons Springfield Hellcat w/ RMSc Footprint Adapter Plate, which converts you RMSc optic cut to the Holosun K cut. The adapter can be found by using the link below:

This is ~4th or 5th Holosun dot. Prefer the Green with selectable reticle configurations. This one is for my 1301, recommend the C&H 1301 plate for a nice low mount.
