407C/507C-X2 Series, 2 MOA Dot, 32 MOA Circle Dot Options, 7075 Aluminum, Open, Solar, Shake Awake, RMR Footprint (Red or Green Reticle) (Black, Burnt Bronze)

Exactly what I wanted. Works great, price was ok and delivery was fast.

I was getting one of these because I already have one, and I know they're good. This one arrived sealed and in fine shape.

very nice

Really nice red dot - very bright dot that is easy to pick up and track with - have not had any issues with durability.

Using it on a Glock 23, very satisfied with it. Should’ve bought one sooner.

This 407C/507C-X2 mounted up clean and held zero through everything I've thrown at it so far. Fit and finish feel every bit as tough as Holosun's reputation suggests — dense, textured housing with zero flex or creak. Installation was straightforward: bolted down, torqued to spec, co-witness height was right on the money with no shimming. The 2 MOA dot is crisp and small enough for precise work without swallowing the target, and the windage/elevation clicks feel positive and repeatable — no mushy adjustments. Footprint is compact and low-profile, doesn't add bulk or snag. Where this thing really separates itself is power management: the solar failsafe backs up the battery, so a dead cell doesn't mean a dead optic, and Shake Awake means it's live the instant the gun moves — no hunting for a power button under pressure. This is buy-once gear. PROS: - Dense, tough housing — takes abuse, holds zero - Crisp 2 MOA dot, positive/repeatable adjustments - Solar failsafe backs up the battery — no dead-optic moments - Shake Awake — instantly live on movement - Compact, low-profile footprint CONS: - Battery tray access takes a minute to get used to - Costs more than entry-level dots in this class VALUE FOR MONEY: You're paying above entry-level, but solar backup plus Shake Awake alone justify it — reliability you're not getting from cheaper dots.

I am very happy with this purchase! I just received my Springfield Echelon 4.5F with Gear Up package. It comes along with extra magazines etc., with a factory installed Viridian RFX11. The RFX11 is fine product for what it is, but I had a problem with acquiring the dot, having to remove the sight to change the battery and plastic construction, lack of adjustment etc. The Gear up package come with Pin Set 1 required to mount the Holosun, but I had to purchase #6-32 8mm screws for installing it. My Gear Up had screw set 1A but not the required screw set 1B. This is very important. This Holosun mounts directly to the 4.5F without any additional plates. My HE507C-X2 GR is a Huge upgrade. I leave it in Auto Mode with the Dot and Circle a it is very easy for me to acquire the target. I preferred the GREEN Dot over the RED Dot as my 70 year old eyes can better focus and acquire the target. The only drawback for me is that the Intensity does not transition between light and dark to my satisfaction. I simply click up + once for day and click down - for evening. Overall excellent value..

Great made optic with a great brand. It just didn't fit my needs. It may not allow for co witness without changed the iron sights.
