HOLOSUN HE507C-GR X2 / HS507C X2 2 MOA Dot & 32 MOA Circle Open Reflex Pistol Sight - Durable Shake-Awake Solar Failsafe Parallax-Free Aluminum Sight for Full-Sized Handguns - Green & Red Dot Options

I purchased this to replace a Vortex Defender ST that has MAJOR design and hardware flaws.Do yourself a favor and spend the extra $40 bucks and avoid the headache and hassle.The 507c/407c series of optics just work, the buttons are easy to access and manipulate, but not easy enough to inadvertently access and change your brightness/settings like the Vortex. Smaller battery but double the battery life, if you can explain that one to me, more power to you.Holosun just makes a better optic. YMMV but for me, this does the job and does it well.Also, if you're on the fence about forking out the extra coin for the 507c with the "donut of d*ath" reticle over the dot on the 407c, consider this...1 moa is roughly the equivalent of 1 inch at 100 yards, so a 32 moa ring becomes a 32 inch circle, a 2 moa dot is 2 inches, and so on and so forth... But what about at 10 yards, 1/10 the distance? That 32 inch circle becomes a 3.2 inch circle, and that 2 inch dot becomes 1/5 of an inch.It's not going to make you a better shot by any means if your fundamentals suck and you don't practice, but when the adrenaline hits that ring is going to help you focus on that dot and make the hits count when it matters.Hope this helps.Also, side note, Holosun introduced a rolling change to their battery trays, the screws are now captured and "rachet", scared the living daylights out of me at first because I thought I stripped the screw but then I noticed that there's a ring around the screw for the battery tray now and after a little internet investigating, found out why.

This a really nice sight and I'm really happy with this purchase.

I think this is best red dot sight for the money. Especially the solar power feature

Super fast delivery!Product as described, fits like a charm.

fast shipping

Awesome product works great right out of the box as its sighted in for 25 yards. Fit perfect and the accuracy was spot on!

I like this product quite a bit. The green is easy to ID. This is my 4th Holosun and this one doesn’t disappoint. The challenge is the mounting plate…. I have had more challenges getting the right one, but that’s nothing on Holosun. Would buy again.

Normally this would have gotten five stars. However, this order presented with several issues, first it appeared to be used, now, this is not a huge deal, as these items are tough and built right, but, the biggest issue is that despite the description stating that it comes with a picatinny rail, it doesn't.....
