Solid, but eats batteries - OpticsPlanet Exclusive Firefield Charge AR Laser Sight/180 Lumen Flashlight Combo

This little laser/light box is packaged in a durable metal case. The remote momentary switch works well, but I do not like how much play there is in the socket to connect it. The momentary switch's wire length is appropriate to mount the unit above or just in front of an AR receiver and have plenty of length to reach common hand hold positions, or to mount it in the front and have it reach a fore hand grip position. I would like to see a water tight cover for the remote switch socket when it isn't in use.

The elevation/windage on the laser is easily adjustable with an Allen wrench/hex driver. I haven't taken this to the range yet, but I wouldn't be shocked if I need to use a little LockTite on the elevation/windage adjustments to keep them from moving. They do not have detents to click into as they turn -- it is a smooth adjustment with no locking mechanism. To avoid problems, have LockTite on hand.

The flashlight is good strength and cone spread for indoor and close quarters combat situations, making it excellent for home defense. This is not adequate for hunting or most other other outdoor shooting.

When a battery wears down, the first indication is the laser will go off if the flashlight goes on, but both will operate fine independently. Always test your battery power by turning on the light and the laser at the same time. Not doing so can lead to the nasty surprise of having the laser working during range time, but at night for home defense, the aiming laser disappears when the light goes on! During the time I was trying out some different hand grips to tweak my setup the battery went from full to not powering both laser and light. This is also disappointing because there's still clearly a lot of juice in the batteries.

A side note: I am considering buying 3.7v rechargeable batteries of the appropriate type for this (instead of 3.0v non-rechargeable)--the higher voltage might extend the functional life (that is, the portion of the battery's charge that's high enough voltage to power light + laser) longer, even if the mAh rating is the lower on them.
