Peterk2's Review of Firefield BattleTek Green Laser Sight
It looks like the sight was designed for a rail on a handgun, but I am using it on an AR 15 .223 as a close quarters primary or backup for my 3X illuminated prism sight, and it seems to work well in that role.
The sight was easy to mount on the upper handguard rail where I can easily turn it on or off with my thumb (or finger if I wrapped my hand around the fore-end a bit more to use the other switch) - switches on both sides extend behind the body of the sight. The switches are on or off without a momentary on option. My unit would not turn on or off unless I pressed the center-forward portion of the switch, so if you plan to use this for defensive purposes, you want to make sure you know where to press. The upper, rear, and lower portions of the switch didn't work for me.
It is short enough (1" above the rail) that the prism sight looks above it, and I can't see the laser at all in the sight. It is
about 1.3" wide and 2.5" long including the switches on the rear.
It is tall enough that you can use a very low offset mount in front of it for a light (laser about .40-.45" above the rail).
Fortunately, my prism sight was sighted in for 100 yds, and it was quick and easy to move the laser to match the prism sight near dusk when you can see the laser at 100 yds. It might be much more time consuming (and ammo consuming) if you didn't have your iron sights or optic already sighted in. As an fyi, there are no "clicks" or gradations, and a barely perceptible movement of the allen screw for sight adjustment is about 1 moa.
After the first range session, I checked sight alignment, and the laser had moved about 2" compared with the optic - not much at all for a sight that will likely be used at less than 100 yds, and not surprising when there is only one, somewhat small clamping screw. I haven't noticed any movement since the laser has settle into its slot.
The manufacturers claim the green laser can be seen at 50 yds in daylight, but on a sunny day, I couldn't see it easily even with a 3X scope. It shows well at 25 yds in daylight which is better than my CT red laser. Likewise, the claim is made that it can be seen up to 600 yds at night. That may be true if you use a very bright scope or night vision, but the best I've done is about 200 yds just before dark when you can still identify shapes.
There are no rain covers for the elevation and windage adjustments, but the adjusting screw is so small that it might make much of a difference if you don't expose it to a monsoon for days on end. Would be easy to put some electrical tape over the screws to provide more protection.
I've only fired about 100 rounds so far with the laser in place, so I can't comment about long term durability. Will update this review if I have more info.

Pros:
- Decent price. Decent performance.
Cons:
- Not quite as powerful as advertised. Switches less than ideal.
Best Used for:
- 25 yd daylight to 100 yd early dusk hunting, defense, plinking.
Would Recommend:
Yes
