    Outstanding value as long as you appreciate the limited features offered. Very easy to install with drill press and 6-48 tap.

  2. perfect fit review by R May on 6/27/2017

    I was asked to put a rear sight on a Remington model 513T. I found that it originally came with a peep sight. The Williams sight fit perfectly! You can also get different sized apertures.
