Good concept - NcSTAR Tactical Red Laser Rifle Sight w/ Universal Tri-Rail Barrel Mount

Decent product for casual use. First don't over tighten. Frame is hard plastic which is fine. Downside is that it doesn't hold zero for long. Especially when rifle is cased and stored or traveled. Upside is its easy to re zero. Caliber will make a difference. Its on my s&w m&p 15-22 Nd works great. Prob wont go on any higher cal rifle tho due to going off zero. Definitely recommend for casual shooters.
Pros: Mounts on barrel for more rail space
Cons: Doesnt hold zero when rifle is cased
