Review on Green Dot Laser Rifle Scope With Picatinny & Ring Mount, Remote Pressure Switch - 532Nm Two-Dot Gun Sight by Patrick Goodrich

Ok, so many ppl writing reviews here fail to realize that the battery included doesn't come fully charged. And complain that the unit "EATS BATTERIES ". false.Unfortunately, the laser doesn't come with a charger but no biggie. I found one on Ebay with 2 spare batteries for $14. I went shooting all day and didn't drain 1 full battery. I shoot an AR-12 (12GAUGE) and it held zero through the 170 rounds I put through it. A lil tip: when installing, turn on the laser and turn the unit until the dot is dead center with the end of the barrel then tighten to secure. By doing this, you shouldn't even have to adjust the elevation/windage adjustments. Mine was DEAD ON all day. I installed one on my wife's keltec sub 2000, lined up the green dot to the end of the barrel, secured it and hit dead center target at 150 yards with no adjustment. The laser is VERY bright and have no problem seeing it from 200 yards. I'm gonna buy more of these to sell in my thrift store and mark the price way up. :) the battery size is cr123a. Order your charger now cause the battery provided won't have much of a charge in it AS WITH MOST BATTERIES. I promise you, for what this unit offers, it's a steal. And I suggest using the pushbutton on it and not the corded button. It looks cool on your weapon but it's just not practical. You will eventually snag it on something. Cheers.
