This is one of the most affordable green lasers we've ever carried. AIM Sports products are rated for real firearms use, so there's no need to worry about your unit staying zeroed in the middle of the action. The unit includes external adjustment knobs for the beam not unlike the windage and elevation knobs found on standard rifle scopes, rather than the internal set-screw adjustments featured by many comparable models. Beneath their covers, the knobs can be adjusted by flathead screwdriver, which many players would have easier access to than a correctly-sized Allen key. This laser unit complies with federal regulations and comes out at 5 Watts.
