(1 out of 5) Do not even think about getting this
by from Arlington, VA on

It is simply not worth the words to explain why you will be disappointed with this purchase if you buy this sight. Simply don't do it. I cant even fathom how this got approved for production, let alone for anything more than $5, but then the shipping to receive this chintzy junk would be worth more than the product received. Do yourself a favor, save your money, avoid disappointment, and prevent anger for not having listened to me. Just move on and do not even consider this sight. Its THAT bad. Make yourself a higher quality sight out of paper clips or something.

There is inexpensive and there is cheap junk. This is cheap junk. Was less than impressed by its physical components but thought i would give it a try. The 1st impression was right. Failed in less than 500 rounds. Junk.
