Pivot mounts are a special kind of repeatable mounts that are especially popular in Europe and mainly produced by European manufacturers. Most notable among them are German Companies like EAW (Ernst Apel Wurzburg), Recknagel, Henneberger and MAK. These Companies were also among the first to produce mounts of this type. Non German companies like Rusan are also following this trend.
Main benefits of pivot mounts, or swing mounts as they are sometimes called are:
extremely durable; most mounts of this kind are tested on 10000 or more reattachments,
size and weight; light and small, elegant.
There are also some minor weaknesses that such mounts posses and they are: they are usually more expensive than other types of mounts, the installation on the rifle should be done by a skilled gunsmith and most of these mounts are higher than 14 mm.
A distinct feature of pivot/swing mounts is the way the scope attaches to the rifle. The front foot of the mount on the scope is inserted in the front base under a 90 degrees angle to the barrel. Then the entire scope is pivoted around the front base until it is locked into position by the rear base.
Pivot mounts of all types enable windage correction on the rear base at the time of the mounts installation. There are three main types of pivot mounts which are distinguished by the type of the rear base:
EAW style rear base: produced by EAW and Rusan,
Dovetail rail base: produced by Recknagel, Henneberger, MAK and others.
