Bul Armory Optic Reflex Sight SAS II Ultralight

Holosun HS507K-X2 ACSS Vulcan Mounted to the SAS II UL!

This optic is a lot smaller than I thought it woudl be, but it’s also made for smaller handguns (which is why it’s denoted as 507K).

It was rather easy to remove the “iron” rear sight. In fact, the rear sight was loose and was rattling around! It was probably due to the stout JHP I’ve been recently shooting.

I bought an optic shim (I also bought an extra one, for redundancy purposes), as the 507K has zeroing adjustability issues with the SAS II UL.

I cleaned out the optics screw holes and then used the screws that came with the optic to secure the optic to the slide (used blue thread locker).

The optic works well! I have it set to use the ACSS reticle, have the lighting dimmed a bit, and have the setting locked in place. I also have the Shake Awake feature enabled.

I’ll have some time to shoot it tomorrow (will try to visit a new range, as well).
