Save money for a better laser - NcSTAR Gun Accessorie - Pistol & Rifle Laser With Weaver Base APRLS

To make a long story short, this laser is well designed. Four screw windage/elevation system locks the laser tightly in position. But these four tiny screws do not last. Those tiny holes on the back of the screws where you insert the Allen wrench quickly wear out, even before the laser was really sighted in. I have not been able to obtain replacement screws from NcStar despite numerous attempts.

Therefore, if you can sight it in really fast, buy it. Since I need more precision and need longer time to sight in, I won't buy another one.
Pros: well designed
Cons: easily worn out
