It is sturdy and easy to attach.  The problem is that the dot is very fuzzy and makes it hard to sight in.  I have not used it on range yet .  I advise not to buy this scope

It was a bit of a leap of faith to buy this brand new product at this relatively high price for a red dot sight with laser. However, I have a low priced Tru Glo red dot which has worked flawlessly and reliably on a 45 carbine for over a year, so I took the chance. So far I am very pleased with it, had it for two weeks. Put it on an FNH PS90 5.7X28 carbine and have fired about 200 rounds with the sight on with no problems yet. The plusses are:

military style pushbutton integrated controls
one cr 123 battery operates both red dot and laser
red dot and laser are independently boresightable
red dot view is very clear and the dot is crisp
red dot adjustment caps are captive
manual is in good clear english
red dot boresight adjustment is very fine for easy sighting in

The minusses, not enough to not rate 5 stars, are:

laser boresight adjustment is very coarse, making it tricky to get it just right
laser adjustment cap is not captive
only one reticle
can't bring the laser to match the red dot by looking through the red dot because pointing with the laser through the red dot sends the impact high (why I don't understand)

If this holds up under the relatively benign recoil of the PS90 I will get one for an AR-15. I am recommending this to my gun friends.

I really like this sight so far. Have fired 50 rounds since installation with no problems. The 4 reticle settings and 7 brightness settings are a great asset. I have another red dot sight that was 3X the price & doesn't work nearly as well. Don't think you can find a better sight for the money.

I finally took my new Colt M4/.22 to the range and decided to put this sight on for starters. It did make the gun look sleek! I was shooting at an indoor range and pushed the target to the max 25 yds. I've never used this type of sight before and had no problem adapting using both eyes to aim. My groupings were about 1 1/2" using 10 rounds per bullseye. But... everything was high and right. I tried in vain to adjust the sight and saw little difference in adjustment down range. So, either the sight is just off or I don't know how to use an allen wrench! Overall, I paid $40 for this sight on sale at a local sporting good store. I do like the build quality and the supplied wrench adjusts/tightens all screws. I will attempt another sighting-in next week and I'm also going to use an inexpensive red dot for comparison. I do like shooting with it.

Im very disappointed with this red dot. I must have received a defective one because I do not have a dot. It is an oblong ovoid shape. I short a friends rifle with the same red dot and his was much better.

Update: Changing my review to 5 stars. After showing this red dot sight to several others and doing some research online, I have discovered I must have astigmatism, despite no other visual issues in daily life. The dot is perfectly ground to others. Also, if I rotate the entire red dot sight, the image does not rotate, rather it stays in the exact same position. I now have an appointment with an opthamologist

I have not been able to test the red dot sight yet as work keeps me away from my hobbies. The site is now mounted on a pistol, ready to be tested.
I hope to test this sight sometime next month.

I WANT to like this sight, as Weaver is a good Texas company, and I have had excellent results with their optics in the past. I like the size of this sight, the controls for the dot are on the front and easily operated. I have mine on a Ruger Standard .22 LR semi-auto pistol, and it would be nice to find a mount that replaced the rear sight in that dovetail for a low profile, but instead I had to use the much higher B-Square mount that clamps to the receiver. I have found the "dot" to show more "bloom" that I would like, but for the price of the sight and my intended use on a .22 "plinking pistol" I can live with that. On the subject of price, I may have overlooked it, but I did not realize I was buying a used sight until it arrived. Learning to double check every detail on all Amazon orders!

Great compact red Dot for the price. Mounts and co-witnesses perfect to AR15 M&P Sport 2 using UTG Med-Pro .83 inch Mount. I would use this red dot on my other firearms.

Great sight!
Easy to mount and set up was fast out of the box!
*it sits low and blocks my flip up iron sights so I may go either with a riser or change it out and use it on another rifle other than my Windom  AR.
Has been good under live rounds so far. Less than 200

Purchased this CMR-206 for my Walther PPQ M2 and got them fairly quickly and with a great price!  #4 Slot is designed for the Walther PPQ for quick and easy installation. Fits perfectly. The green laser is visible for at least 50 yards during the day. Got to the range and sighted in with 1-2 inch groups at 15 meters which is where the Walther PPQs are sighted in from the factory. The first shots were a good 6-8 inches high and an inch right. Adjusted .40 of a turn up and .10 of a turn right. You adjust where the bullet hits not where you want it to go. Laser dot ended up where the front sight covers .75 of it. You can still see the laser but very slightly at 15 meters. After getting bulleye's at 15 meters without using my front sights, I tested at different distances. At 25 yards the laser will be above the front sight. At 3-10 yards the laser will be below the front sight, you can't see it. There is a difference of 3 inches between 3-25 yards from center. 3 inches down and 3 inches up. 6 inches total. I figure I can hit center mass with that.

Love this red dot.  for a fraction of the price of Aimpoint T-1 you can't go wrong.  I put through 700 rounds and it still maintain zero settings. I had to replace the high riser mount that came with it with a UTG medium riser mount so I can co-witness with the iron sights.  I'm not much of a fan of 1/3 co-witness so this worked out good for me.  If you don't want to spend $500 or $600 for a red dot this will do the job.  Enjoy!!

I shoot this indoors and the 4 MOA is perfect.
Tracks well on my SW22 Victory.
I would recommend this sight.

Really stiff out of box took about 30 cycles to shift smoothly. Magnifier sit a little high for sightmark QD reflex sight, about 1/4". May try riser but sights were set dead on and hate to change them.  Heading to the range tomorrow to see how holds up with some real action.

Excellent target for up to about 20yds. With iron sights. Good quality.

So far so good.  It alreadu lined up to my UTG red/green dot, so I'm good to go.  It's a little stiff to move to the side and back, but thats fine, makes it more sturdy.

This red dot manufactured by Leapers for UTG deserves five stars for what it is, but if you are considering the purchase of this sight, you must be cognizant of what it isn't. This unit is marketed as a Close Quarters Battle sight and for that purpose it is excellent. The optic lenses are very clear, the 30mm objective offers a wide field of view, the 5 power levels in both red & green dot allow you to pick both the right color & intensity dot for any lighting conditions, the rail mount is solid and holds the sight well, and the unit zeroes easily and holds zero under heavy recoil. I have this unit mounted on a modified H&R Pardner Pump Protector 12 gauge and this scope allows for rapid, accurate, two eyes open target acquisition at close quarters.  For a home defense type situation, this is an excellent scope that will allow you to rapidly acquire and put your shots on target.

If what you are looking for is a red dot scope for use beyond close quarters (say beyond 75 feet), then this is not the optic you are looking for. There is noticeable "starring" of the red dot, particularly at higher power outputs, that would preclude this sight from providing precision aiming at extended distances. It's not a shortcoming or problem with the sight, it just isn't the role it was designed to perform. It is after all marketed as a CQB red/green dot and for that usage it is an excellent choice. For longer range precision you will need to look at other options.
