Perfect for my MP5. Going to order for all my PCC's. Also for my M4 shotgun. Get yours now

Well made and feature packed!!

When I first unboxed this, I was a bit disappointed, and was going to send it back, but I ended up mounting it and have now shot over 1000 rounds with it. (Reciprocating slide, 9mm)Pros: It’s an RMR/SRO footprint so it’s easy to find a plate. The 2moa red dot is daylight bright even in full sun, it seems to be more of a 4moa on full power. The refresh rate is good enough that you don’t get a lot of spider webbing. Holds zero 100%. I’m still using the original battery after 6 matches and it’s still bright.Cons: This is not an SRO. Compared to an SRO the window on the USA is not as large and the glass is not quite as clean. (Very minor differences if I’m to be fair to the price point) The biggest issue I had was mounting the optic onto my plate. The optic was just the tiniest bit off but with a little garage gunsmithing, I made it work.I hate to say “for the money it’s worth it” as sometimes people are turned off by that but it is definitely cost effective. In my opinion it’s a good budget optic.

***UPDATE: DID NOT WORH WITH NEW BATTERIES, CONFIRMED RETURN AFTER FURTHER INSPECTION, PLEASE CHECK PHOTOS AND READ FURTHER:Went out and got a pack of new CR1632 batteries and tried one in, still would not turn on. Double checked instructions, tried every button combination possible just incase the directions were some kind of poor translation. Nothing. Figured I look at the windage and elevation adjustments as a last resort and that's when I noticed thar the notches looked to be all buggered up by someone previously. Check the uploaded picture. Packing it up and returning. I actually want to try and get a replacement because if it would actually turn on it feels like a decent red dot for a range toy. Will update again after hearing seller response and/or receiving a working replacement.***Not sure if I'm receiving someone else's return but there was already a battery inside the compartment despite the directions indicating it should have initially been empty and I'm supposed to be putting the battery in as part of the beginner guide steps. That battery was dead. Going through the included hardware there was another battery but it was a size too large for the battery compartment. So the instructions says it should come with two batteries and I got one dead one pre-installed and one that's the wrong size.I gave it two stars for now, cause right now I don't even know if this thing works but I'm going to have to make a trip to the store buy batteries to find out. Potentially 1-star if I buy batteries and it still doesn't work. Redeemable if it works with new batteries and/or the seller reaches out with an explanation.

Great sight at a reasonable price.Mounted with a 1/2 inch riser on a SUB2000 Gen 3 and I'm impressed. Came with RMR and picatinny mounts, mounting & adjustment tools, rubber protective cover, and 2 batteries. It's 200+ rounds in and the dot is crisp with no haze and holds zero. I really like the fact that it's rugged but not chunky like a lot of red dot sights. You get a quality product for your money. This sight is a winner.

This optic is top quality, with a large (but not too large) sight window. The red dot is very bright and well defined, plus the field of view is amazing. Very tactical on/off and brightness buttons. Very much like $550.00 red dots. Also, the shape is clean and simple, ie professional. Buy one!

I mounted it to a 12ga. home def. shotgun and so far, so good. It mounted well and so far works as advertised. We shall see how it fares after a couple boxes of high brass loads are run thru the gun.Fingers crossed!!

5 stars for form, value and function as long as it keeps working and holds zero. Will update if it fails.I shoot the optics divisions in USPSA and own two Trijicon SROs, a Sig Romeo 3 Max, and a Holosun 407. I purchased the UUQ optic to mount on my Buckmark 22 for inexpensive cross training. The housing of this optic looks robust, but the circuitry can be suspect on budget optics. So far, it seems it will hold up well when frame mounted to a 22 pistol or rifle.At first glance, it looks very similar to a Trijicon SRO with respect to size and overall design. The SRO is the gold standard for slide mounted competition optics. The window of the UUQ is as wide as an SRO, but not quite as tall. The footprint, shroud design, button placement, top loading battery, and overall aesthetic all scream SRO. The window size and overall dimensions are more like a large-window competition optic, and less like a low-profile carry optic like the RMR or Holosun 407/507. The larger window makes it faster to acquire this dot and easier to track it through recoil and transitions, but large window optics like this tend to print more under clothing and are less durable when dropped.The 2 MOA dot looks much larger at medium to higher brightness settings. Functionally, it looks similar to the 5 & 6 MOA dots on my SRO and Romeo 3. Larger dots are preferred by most practical pistol competitors for fast target acquisitions, speedy transitions, and tight shots out to 25 yards. I like it. A bullseye shooter might want a smaller dot. The dot is perfectly round when viewed through my good eye, but blossoms into a bit of a blob when viewed through my eye that has astigmatism; same as all my other red dots.Shake awake works as intended. Nice feature at this price point.The optic is packaged in a small Pelican-style case, just like a Trijicon. It includes a spare battery and all the tools necessary for mounting, battery replacement and windage/elevation adjustment. I used the picatinny mount to fasten it to the Tactical Solutions picatinny sight rail on my Buckmark. The mount is a bit loose in the slots, so you'll want to push it snug forward before tightening to make sure it is centered, and to keep it from shifting under recoil. I didn't do this the first time I mounted it and ran out of windage adjustment trying to zero; it was slightly crooked. All of the mounting screws have blue Loctite applied at the factory. Nice attention to detail.The optic comes with a functional rubberized dust cover. It is better quality than what came with my Romeo 3 Max. My Trijicon and Holosun optics did not come with dust covers.Overall, I'm impressed with the design and function of this optic at this price point. I get lots of skill carryover between the UUQ and my SRO/Romeo optics. My 22 with this optic is perfect for practicing strong and weak hand shooting without burning up expensive ammo. It would also work well for rimfire divisions in plate shooting and Steel Challenge. I wouldn't expect it to hold up to 1,000+ rounds a month of centerfire ammo , but I'm cautiously optimistic it will hold up to 500 rounds a month of 22 LR. No issues after the first few hundred rounds. It looks sweet on my Buckmark and it works great.
