Botach came through with my order. Received 8 days later. I'm pleased, considering how much cheaper they are than ANYONE else. Thank you botach.

Opticsplanet is cheaper with their 14% off coupon the the FDE version of this sight. (Botach charged tax and Opticsplanet didn't)

I just bought this from botach, it was defective straight out of the box! The front lens is crooked and cannot be adjusted. Not a good experience with Holosun, not sure how good Botach customer service is...

Not defective. The front lens is designed that way and works great. From Holosun:

"The angled objective lens is part of the design. All red dot sights have to have a bit of an angle on the objective to allow for the light from the LED emitter to bounce off the inside surface and be reflected to the shooter.

"The Holosun design is a bit steeper than many and this allows for the emitter to have an extremely low profile so that it does not intrude into the inside of the tube and obstruct your view. The angle also reduces reflection to your target."

Where do you guys see the option to select a mount? I don’t see such an option but it does say in the description: 2 MOUNTS INCLUDED, Low mount & 1/3 Co-witness mount

Huh? Two mounts are INCLUDED with your purchase. You get both mounts and use whichever you want on your gun. Throw the unused mount in your parts bin.

Not paying sales tax to Nevada blows the deal for me.

Hmm, not paying sales tax to Nevada blows the deal? So you want to pay Nevada sales tax?

And, for what it's worth, regardless of the lack of punctuation usage, there is not tax charged to me for ordering to Kansas

Unfortunately that’s the way it is now. You’re not paying sales tax to Botach’s home state, but to your own. It’s an internet sales tax that our find folks in DC passed and now is running. As for the sight itself, I’m a convert from Primary Arms now. The dot to me is much clearer and the wake up feature is very nice.

Ordered in last week and received it a few days later. Great price for an awesome red dot. As far as I’m concerned, based on 5 purchases with this retailer they’re good to go

That’s a great price but I would not trust botach tactical at all. I ordered a couple “in stock” mags from them once and didn’t get them for 4 months. Sent multiple emails and called and never got a reply or a tracking number.

Spent $40 more than that less than 6 months ago! As always, electronics prices fall, altho' given this has optics as well I wouldn't have expected it to fall this far, this fast! Smmmokin' deal, if you're in the market for a RDS...

Don’t recommend buying from botac. Purchased this item was shipped without mounting screws. Used it as a paperweight for a month before the screws shipped.

I'm getting a lot of side glare on mine. I took a sample video and put it on YouTube, could you guys look at what mine looks like and see if it's normal? The smallest amount of light behind me causes glare https://youtu.be/LA7mkTVFvzo

What direction is your front glass angled? Mine is angled to the side and I get terrible glare, but if I turn it 90 degrees it's much better https://youtu.be/WoGuWptdTWk

I ended up ordering 3. 2 came in the white box. The 3rd didn't ship as thy ran out of stock. I did recieve it about a week late but ended up getting a normal Holosun box, came with both high and low stock mounts, normal instructions, everything. Plus it came with the battle steel mount so that was cool there is no difference between the sights in generic boxes vs something you would get at optics planet other than being some sort of overrun minus factory mounts. I called Holosun when I didn't get screws in first order. Holosun told me they are aware of the version botach is sellingand can't help as they didn't provide mounts or screws to botach. Thus botach would have to help me and they did. Great deal when they were at $141!!! I really like the battle steel co-witness mount as well! Much better than stock Holosun mount or the low profile Qd mount which is kinda wonky. No locking machinism but what the heck it was free. Kinda wish I would have ordered more at that original price point.

Looks the same. Does the dot and circle dot. I didn't do much beyond that. The foam container has the same accessories and cutouts as the usual Holosun minus the stock low mount being gone. I chose the quick release mount that of course came with no screws. I received an email yesterday though indicating screws are being mailed without contacting them. So I think they figured out what was going wrong.

I think they read this thread. I got an email indicating screws are being mailed without asking. Sight I received is white box but functions and looks like the real thing.

Hmm, I have it coming with the QD mount too. Hope I don't have to look for screws too. So people are suspect a chinese ripoff of a chinese product?

I think the warning sign is they let you select a mount... This made me hesistant, but went for it anyway.

I think they have a bunch and are mixing and matching parts to get stuff moving. I have a real 503GU at home that I'll compare to mine when I can check tonight.

Let us know what you figure out when comparing the new one with your current 503GU

Has anyone else received one? I have other Holosun sights, and received mine from Botach today. Based on the packaging (plain white box versus box and printed sleeve on others) instructions (printing and manuals are different), and lack of mount, I think that the one that I received is not a real Holosun.

New to shooting. Just bought the Ruger AR-556 MPR. Will this sight work on that? Is the "HoloSun 503GU w/ AR15/M4 True Co-Witness Flat Top Mount" The correct mount to choose for the Ruger AR-556 MPR? Thanks for your help!
