Pros: Bright, visible green laser, long battery life, quality product, major intimidation factor
Cons: Difficult to get a final set in zero.
I am writing this review as a police officer in Colorado with over 5 years of experience. I have always considered myself a gadget guy, and have to have the newest, coolest things. Thats one of the reasons why I purchased the AimShot LS8200 12mW Green Laser. I have this laser mounted under the front sight of my M4A3 rifle (along with a bunch of other toys). I did this using a rail mount.
This laser comes with a pressure pad to activate it for a momentary on. This laser is incredibly bright. I have been able to see this laser on target at 100 yards on our range days during daylight with no cloud cover. The laser dot is visible to at least 2.5 miles at night. If you are in a low light, or dark situation, believe it or not, you can actually see the laser beam mid air, as if it were a clothesline from the weapon to the target.
If you were to shine this along with any standard 5mW red laser sight, you would be blown away at the difference in the brightness and how much of an attention getter this is to the shooter, any witness, but most importantly the suspect you are pointing it at.
Would I trust this laser as a sighting device? Well, probably not, but that is a personal preference, I would still trust my optics or iron sights over my laser any day. The primary reason I have this laser is for the intimidation factor of having a perp see that on their chest, and decide to give up. The coolness factor helps too. Several officers in my department have purchased this laser to attach to their duty rifle.
The LS8200 laser takes one CR123A battery to operate, and you will get about 5 hours of constant on time out of one battery. The laser unit does not seem to be effected by the extreme cold of a Colorado winter night, as some other electronic equipment is known to fail during.
The difficulty with this laser is getting it zeroed. To do this you must remove the cap off the business end of the laser, and then there are a series of 4 small screws which place tension on the laser module head and will adjust it on an X / Y axis. Now this can be a bit of a process, and getting it tightened down securely is another problem. You may think you have it down good and tight, but after 3 or 4 rounds fired at the range, your laser will be 2 to 3 feet off target at 100 yards.
Dont let that discourage you Once you have it zeroed and tightened down IT WILL STAY. I now have mine where it needs to be, and have fired over 2,000 rounds through my rifle since it has needed any adjustment, and I have all of my rounds hitting within the laser dot at 100 yards. Now keep in mind at 100 yards, the dot which will look pin point to the shooter, is actually about a 3 inch dot if you are on the receiving end (which I tried to see what it looks like at night, just a little scary).
If you have the patience of dealing with the sight in, and are in to gadgets, or just want a quality long range laser for your weapon, then this is an excellent choice.
