Best Review on Tactical Foldable Vertical Adjustable Positions

I'm using this product on a KWA M4A1 airsoft gun with traditional weaver mounting.

The good side:
It has all the features you would need for a good airsoft scope and one of the cheapest. Its bright enough for playing in the sun, it has a wide range of adjustment in the dot to pinpoint where your bbs are hitting, it has a front cover that protects the lens from being hit without obstructing any of your sight line (I know it looks like it in the picture, but it does not cover any additional space, it only can cause a glare the makes your view somewhat hazy), and the dot is tight and compact (its not a blaring spot light that blocks your view, especially the green dot). The adjustment moves in small increments (clicks) and is easy to get the dot exactly where you want it. The scope is made with a strong material. It raises enough with its own mounting to allow a paintball mask to be worn while looking through it, though you only see through about 3/4 of the scope sightline (which is enough to see the dot). The front sight on the M4 does block some of the scope sightline but the dot sits high enough above the front sight so that you don't even notice. The scope came with an extra battery (remember to turn your dot off after your don't shooting, its easy to forget and can run down your battery).

The 1 down side:
The scope will hold firmly to the rail without shifting if adjusted properly, tightening the screws after its aligned just right. Sometimes on my rail the scope can wobble/pop/shift a few millimeters to the left or back meaning that the hold isn't gripping the rail securely. The scope certainly won't come off and the shift is minor, but it may be irritating. This is not a big problem because with some minor tweaking it will hold perfectly secure.

Here is a guy who did a video review on the product (it will give you a chance to see what the inside of the scope looks like).
