A special kind of repeatable mounts are pivot mounts, also known as swing mounts. They offer 100 % repeatability and can be quickly and simply detached and reattached with the use of levers, buttons and screws, with no tools required. Pivot mounts are extremely durable, lightweight, compact and elegant. Their drawback is perhaps their price, which is considerably higher than the price of fixed mounts with rings and other mounting options. The installation on the rifle should be done by a skilled gunsmith. Most of the times, pivot mounts are higher than 14 mm.
Pivot ring mounts guarantee 100 % repeatability and are available either as one-piece or two-piece versions. They allow simple installation of multiple riflescopes or red dot sights on a single rifle with great amount of interchangeability.
Pivot rail mounts are available in either one-piece or two-piece versions. They allow simple installation of multiple riflescopes or red dot sights on a single rifle with a great amount of interchangeability and 100 % repeatability. These mounts are almost the same as pivot mounts with rings but are intended for mounting of scopes with Zeiss ZM/VM rail, Swarovski SR rail, S&B Convex rail or traditional LM rail. Such setup tends to be a bit higher than with ring mounting, but this is usually not a problem for scopes with 50 or 56 mm objective lens. One-Piece Pivot mounts for rails clamp on the rail of the scope on almost it's entire length and provide very reliable mounting solution.
