I made this out of 6061 T6511 aluminum to mount onto a barrel with a diameter of 0.574".  This was Type 3 hard anodized by US Anodizing. This replaced my front sight on my Saiga IZ-132. I mounted a standard height AR15 flip up front sight and used a adjustable rear AK sight. I'm also selling both the flip sight, the rear sight, and an Ultimak. Cost $75 just to have anodizing.  Selling for $75 shipped USPS priority to CONUS only.  Paypal gift payment only.
