Wobbly.wont stay on target. - NCStar Red and Green Laser Sight with Universal Rifle Barrel Mount and Pressure Switch ARLSRG

Strong lights, especially the green. Mounts and feels solid, have it on an air rifle, the laser seems to move quite a bit after each shot. But for the price, I didnt expect much better.Tried adusting back and forth after every few shots, but to no avail, checked the mount, stayed solid.
