Broke before i ever fired a round. - Barska 5mW Red Laser Sight/Flashlight Combo w/ 200 Lumens

First when I ordered the item I did not see anywhere stating the item was not in stock after 2 months item finally shipped. When it arrived it looked like a good deal. I mounted it on my AR, when I went to sight the laser in the light acted as if it had a short in it and would not always turn on, when it did come on it would often turn off when the gun fired. Didn't matter if I used the pressure switch or the on of switch on the light. When I put the rifle away I must of bumped something I didn't notice as when I went to check the batteries just in case that was the issue, the selector switch was broken off. Save your money and but something that will work. I am planning on returning it to the factory not sure if I will get a refund or not. Glad I checked it out before I needed it.
