ホロサン ドットサイト HS407C X2 HOLOSUN

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).

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

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

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.

This is the 2nd 407c I've had and absolutely love it. Put it on my xten 10mm and will hold zero of 170gr up to the 200gr double tap ammo ive tried. Absolutely incredible and would but more of these
