Picatinny rail consists of slots with 5.23 mm spaces between one another, which means that it can be used across its entire length. It is simple to mount and interchangeable – if something is made for a Picatinny rail, it will fit regardless of the manufacturer or manufacturing date. It is affordable, resilient and reliable – this is why it so commonly used by professionals and military. Because of all its great qualities, Picatinny rail has been dominating the rail market in the recent years.
Picatinny is a big step forward from the Weaver standard. Weaver has a few predesignated slots while Picatinny has slots all over its surface, allowing the device to be mounted wherever the user finds it fitting. Weaver's slot is 3.8 mm wide, which is why ring mounts made for a Weaver rail will also fit on a Picatinny rail while ring mounts made specifically for a Picatinny rail will not fit on a Weaver rail. This is one of the main reasons why Picatinny is a far better mounting solution.

Browning Arms Company is a manufacturer of firearms and fishing gear with headquarters in America. They offer a wide selection of firearms and are most known for the following firearms: BPS shotgun, A-bolt rifle, X-bolt rifle, BAR semi-automatic rifle and Auto-5 semi-automatic shotgun.
X-bolt SA (short action) features the X-Lock scope mounting system which uses four screws on both of the mounting surfaces – this allows the bases to sit accurately and firmly on the receiver. The SA model can be chambered for the following calibers: .243 Win, 7mm-08 Rem., .308 Win., 6.5 Creedmoor, 7mm WSM, .270 WSM, .300 WSM and .325 WSM.
Browning X-bolt is available in three versions:
When a rifle is available in more than one action length, only two-piece mounts are interchangeable between these rifles (a two-piece mount made for Browning X-bolt short action can also be mounted on Browning X-bolt long action). One-piece mounts will only fit a rifle with a specific action length (a one-piece mount made for Browning X-bolt short action will not fit either Browning X-bolt long action or Browning X-bolt super short action).
Browning X-bolt SA (short action) either has a B distance (see below) of 74.74 mm or 71.74 mm. The length depends on when the rifle was manufactured. If it was manufactured before 2013, the B distance is 74.74 mm. If it was manufactured after 2013, the B distance is 71.74 mm. This mount is suitable for rifles Browning X-bolt SA (short action) with B distance of 71.74 mm.
A: 17.78 mm
B: 71.74 mm
C: 17.78 mm
F/G: 13 mm
BHU: 1.9 mm
Remove all the stains (grease, oil etc.) from the rifle's receiver with a cleaning fluid (acetone). Once the surface is clean and dry, check whether the screws match the rail and the holes on the receiver. Make sure that the Picatinny rail is compatible with the rifle by inspecting the mounting holes on both. Before mounting the rail permanently, apply a minimal amount of thread-locking fluid 278 or 648 on screws and contact surfaces. Be careful not to get the fluid in or near the mounting holes. Carefully clean the remaining excess fluid around the rail with a cleaning fluid. Using a torque driver, screw the screws appropriately (up to 2.2 Nm) – do not overtighten.
The product has a warranty period of 10 years.

A, B and C markings refer to the distances between holes on the rail/mount. A is the distance between the front two holes on the rail/mount.
A, B and C markings refer to the distances between holes on the rail/mount. B is the distance between the holes in the middle (usually, that is the distance between the 2nd and 3rd hole on the rail/mount).
A, B and C markings refer to the distances between holes on the rail/mount. C is the distance between the rear two holes on the rail/mount.
BH stands for Bauhöhe (ger.) which means overall height. It is measured from the mounting surface of the rifle to the lower surface of the riflescope's tube.
Often, the elevation adjustment that the riflescope offers is not adequate to compensate for the bullet drop when shooting at long range. When the riflescope runs of out of elevation, a mount with an inclination is needed. 20 MOA is the most common inclination. With it, the user gains 58.2 cm / 100 m of additional elevation range when shooting at the range of 100 m. This is approx. 5.8 Mrad of elevation.
