The Weaver K4 is an optic that has been around a long time. Today we will take a look at the K4 F, a vintage Weaver that was made back in the day when a rifle scope with a power much more than 4x or 6x was considered too much for anything other than match use.
The Weaver K4 was a top end optic of its day and it is easy to see why. It has a one piece 1 inch tube. The fixed power makes for simple construction with only a ring for adjusting parallax.
Later Weavers were made with the “micro-track” adjustment. These required the use of a coin or screw driver to adjust the optic for zeroing. The K4 F used turrets that are finger adjustable. The clicks are defined and audible. Like most optics the adjustments are in 1/4inch increments.
The cross hairs on the weaver K4-F are the fine straight cross hairs. Hunters later developed a taste and preference the duplex cross hairs and later weavers come with the duplex. I like the fine cross hairs myself, but it is not the best for hunting in woods or around dawn or dusk. The glass on this example is still clear and clean. Of course it is not as as clear and bright as modern optics but for its age it is still outstanding. My Dad bought another K4 in the late 70s and used it all the way up until the early 2000s. It still sees use on rimfire hunting rifles.
You can find the old weavers online if you have a vintage rifle that you want an optic for it from the same period of time but also want one you can actually use and trust in the field, the vintage weaver is an excellent choice .
