Query: Piece of junk

I was really very excited about the price on this, but as soon as I got it I KNEW there was gonna be trouble. I got it very fast, with all the parts, which is the only reason i gave this thing 1 star. As the old adage goes, you get what you pay for. I took it to the range, sighted it in, and within three rounds had to readjust, then, 3 more round, rinse and repeat for over an hour. So i decided to give it a break, sight it in and then go home, the next week i went back to the range per the usual, and put it on to see if it had improved while it sat in my bag (because gnomes tend to fix things at night). But, low and behold, it was off set by a large difference, and so I just gave it the old tin burial. I wouldn't recommend this to my enemy.However, and its a fairly loose however, if you felt like putting this thing on one of your plastic pellet game guns, it might works as long as you never removed it, and that's a HUGE might. If so, good luck with that.
