  1. Great Quality review by Salt Pork Steve on 6/27/2017

    I needed an aperture with a larger opening for closer Cowboy action shooting. This fits my needs just right.

  2. great sight review by Bill on 6/27/2017

    Easy to install on Marlin 336,looks good and works great. Nearly as accurate as a scope at 336 ranges. Even for 69 year old eyes. The different apperatures make this sight very flexible.

  3. Buck Buster review by NYHunter on 6/27/2017

    Williams advertises this aperture as the \"BuckBuster\". It IS faster than the supplied 3/8x.093\" aperture, but the twilight version with brass ring insert is better.
