Good simple ir laser - Steiner TOR MINI-IR Variable Power CLASS 1 Eye Safe Infrared Aiming Laser Pointer

Other reviews stated how bad the battery is and I have to say the battery that came with the unit is near dead on arrival. I got one use of it then it was out. $14 got me a 10 pack of batteries and I'm blasting at full power! I first tried this on my AR, and although it works, it is not feasibly comfortable. I then put it on my Kriss and am very satisfied. It was almost zeroed out of the box, it's lightweight, it shoots an IR laser that I can see practically up to about 50(ish) yards (in my environment). I have an Enforce WML for my IR light source and it doesn't overkill the laser dot.

2 things that might be obvious, might not, 1: you can't see the beam with or without NVGs, just the dot with NVGs. 2: there is no momentary on, if you push/hold the button it brightens/dims the dot. I find the low setting is adequate.

IR lasers are expensive, this is the cheapest option I've found that's not made of chineseium. I think it's good on a PCC, or pistol, just doesn't have the form for a rifle in my opinion.
