Piece of crp - Ruger Top Mounted Deployable Front Sight

I would not recommend this front sight. I bought it even though it had negative reviews thinking river had problems resolved by now. Received defective sight you could turn post with your finger tips as if no detent. Attempted to call optics planet customer service with no luck called ruger and lady at customer service said she never heard of anything like that since its bought the defective sight from third party try to get them to take care of it. If that didn't work they would try to help of I mail it to them. The bottom line is don't waste your money or time buy Magpul.or other quality part not this piece of crp.
