EZshootCompact Tactical Red Laser Sights with Picatinny Rail Mount for 11mm/21mm Rail-Easy Dual-Purpose

Very good product. Easy to adjust.

The laser works just like any other laser that you would buy but the cost is where it's really at you can't buy a cheaper laser and it works great easy to adjust fits on my CO2 pistol easy to install I just can't say enough about this it would even work on real firearms and rifles I highly recommend this to anybody that wants a good laser at low cost

Great laser sight but it a little tricky to get sighted in. Just takes a little time.Works great otherwise

does exactly what is suppose to do and is very easy to adjust

Easy to attach

Stopped working after only a few uses. It mounted easily to a pistol crossbow and was easily adjustable. Came with batteries, but they didn't last long. Now it has stopped working all together. Bought fresh batteries (tested them just to be sure) and it still will not turn on. Didn't expect much for the price, but got less than an hour of operation.

Meh.... The Lazer is a clear dot with a relatively small MOA. The mount appears to be relatively sturdy. Keep in mind that under the barrel sights only cross the bullet tragectory once, not twice like over the barrel sights. The down side to this sight is 2 fold. 1) the batteries are kind of a pain to put in. You need 3 and they flip over easily, so you have to dump them out and start again if one flips; 2). The range and windage adjustments are crazy sensitive. It's almost impossible to get it to stop exactly where you want it. I did not actually measure it, but I bet one turn of the screw would move the dot several feet at 20 ft. Bottom line... It works for what I wanted it to do and the price was right. It has a push button at th back for turning it on. Not sure how practical that is for a gun sight. I'm using it for a wheel alignment tool, so it works well for me.

Works good. Good price
