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

It worked great on my rost Martin rm1f zeroed it for 8 yards at least for my use case that’s really all I ever shoot from when at the range.

Awesome product! Came fast, good price! My only issue with it is the "shake awake"...kinda not the case..if you breathe on it, its on! So just know if you're wearing this for lets say 8-10 hours...its ON 8-10 hours..solar is cool! Get surpressor hight sights as a fail safe like i did.. buy one! Buy a few! Awesome product!

This is my first Holosun and it definitely lives up to the hype. This thing is pretty cool. The brightness of the red dot is on point easy to adjust. The quality seems to be barn and fit perfect on my Glock.

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 recently mounted the HOLOSUN 407C/507C-X2 on my Glock 19, and it works perfectly. The fitment is secure, and it holds zero flawlessly even after several hundred rounds at the range. ​The build quality is rugged, and the side-loading battery tray is a huge plus since you don't have to remove the optic to swap batteries. The reticle is crisp, and the solar failsafe provides great peace of mind. If you’re looking for a reliable, duty-ready red dot for your Glock, this is easily one of the best bangs for your buck. ​Mounting Tip: To ensure it stays rock-solid on your G19, I highly recommend using a tiny drop of blue Loctite on the mounting screws and using a torque wrench to hit the manufacturer's spec (usually around 15 inch-pounds).

Easy to install, solid product. Super accurate.

Quick response on order, all that I expected!

For the price, good product. I had to sight it in. I have been shooting for years. After about a 100 rounds, you should use the some non permanent lock tite to fix your screws and sight in place.
