Things I liked:

The Williams aperture sight is well made. Adjustments are precise. Visible improvement in accuracy over the fine open sights of my HW57. After several hundred shots, the sight has not shifted. I used my HW57 for plinking beverage cans, clay pigeons, and other similar sized targets. I have no problem hitting these targets at distances up to 75 yards. If I see the target, I can usually hit it. I have the same Williams sights with target knobs mounted on a high power Diana Mauser 98 underlever right. The sight has not shifted under the heavier recoil of the K98. I can buy different sized apertures for the rifle.

Things I would have changed:

The Williams Aperture sight is time tested. At the price of this sight, I can't think of any improvements. I have several and have yet to find a complaint.

What others should know:

The Williams aperture sight is value priced and of high quality. It improves accuracy and evokes smiles when you hit a distant target. There is no reticle to break from the recoil of high powered gas/spring powered rifles.

Things I liked:

Easy to install and use. The Height and range of adjustment perfectly matches the wooden version stock on my Avenger.

Things I would have changed:

A version with the TK (target knobs would have been my choice. But They are available from Williams.

What others should know:

They perform as well as sights costing twenty times as much. Don't count clicks, count turns (five minutes per 360 degree rotation). Do this by coloring one of the indentations on the adjustment head and a corresponding mark on the sight body. Always establish a "bottom" on the sight in clicks from your selected elevation in case you lose your attention span.

Things I liked:

It works as an aperture sight once you get it zeroed.

Things I would have changed:

A very basic aperture sight. Adjustments are crude, about the same level as the cheap factory rear sight on a Crosman 1377. The windage adjustment, if it can be called that, has no witness mark, making it even cruder. The mounting screws are extremely small. Maybe they'll hold a springers recoil. I guess I will see.

What others should know:

If you are used to and looking for old-school Williams quality of the 60s thru the 90s, you will be shocked at this. I guess the fact that it is made of aluminum instead of plastic makes it a Williams. Once you get it zeroed---precisely? Good luck---it will work fine. Best bet is forget the absolute idea the Williams meant quality. Perhaps they do, but not at this level. The next step lower is plastic.

  • Michael from USA asked:

    Is this the right one to replace rear sight on Diana Bandit pistol? The sight that came on gun is almost impossible to deal with and I want to change it. Gun deserves a better rear sight!

    • JimA2 from USA asked:

      Will this fit on a Beeman Model 1085 QB II ?

      • Ken from USA asked:

        Will this sight work with a Gamo Whisper front sight?
