Do not eat a bad product
Hey Joe You should send the defective product back so PA can have a chance to make things right with you and so they can inspect the product to let the manufacturer know how to correct the defect
Not a good product

Look elsewhere, don't buy this one. Out of the box, at 25 yards, this laser was sighted off about 6", totally defeating the purpose of a bore sight. I haven't even bothered to try to adjust it yet, because the batteries ran down really quick as a previous review stated. I don't know if its just junk batteries that it ships with, so I ordered some name brand batteries to test with.
Joe, do you think it may have been bad batterys, just wondering.
Do not buy.

This product deserves no stars. Worked for 5 minutes then the laser faded out. Changed the batteries thinking that was the problem and flashed bright for about 5 seconds then same thing. Again I changed the batteries and got the same result. 30 bucks wasted. Ended up just chunking it. Not even gonna trouble primary arms with an exchange or refund. All I ask is that you stop carrying this product. If I had done my research like I normally do I would have seen all the bad reviews elsewhere. My fault and I'll take the loss.
