GREAT SIGHT. IT REALLY WORK 500 YDS!
ITS PRETTY HARD TO ADJUST AND DOESN'T WORK IN BRIGHT LIGHT BUT WHEN ITS KIND OF DARK IT WORKS GREAT. (MOST LASERS THAT WORK WHEN ITS REALLY BRIGHT ARE EXPENSIVE.THIS IS CHEAP
IVE SEEN BETTER BUT THIS IS GOOD FOR THE MONEY
IF YOU HAVE A SPARE $13 DEFINITELY BUY IT!

P.S. THIS SIGHT COULD FIT ON A BB GUN AIRSOFT GUN OR ANYTHING ELSE YOU HAVE --- NOT JUST FOR PAINTBALL! 4 stars

I ordered two units at a very attractive price. However, all six batteries arrived in a corroded condition and had to be replaced. Might be some connection between that and the price. You can buy the batteries online for a lot less than you would spend at a store.

These units (and others that look the same) utilize little laser pointers that have been modified with set screw adjustments. Out of the box they don't aim true (or even close), and it's very difficult to make the adjustments. Do not overtighten the set screws! If you strip the aluminum threads, it's all over. Leave everything on the verge of being loose, take take your time, and keep your cool.

The sights aren't bright enough for daylight use, but are fine for night use. The clamp will fit a 20ga. shotgun barrel, perhaps larger sizes. 3 stars

You cant see the dot in the daylight unless your in a building. So I just basically use it to mess with my cat now. But its great for house to house combat. 2 stars

The Universal Laser Sight is a good purchase for the price. If you're playing outdoors in the daylight it serves no purpose but it looks cool. 3 stars
