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.
Recknagel is currently the biggest manufacturer of mounts in Germany. Their Picatinny rails, known for great fit and finish, are mostly made of high-grade aluminum (a few are also made of steel), which is why they are very reliable. Screws are included. Currently, a common trend among rifle manufacturers is making receivers out of aluminum – mounting a Picatinny rail made of aluminum on one of those receivers is thus not problematic. Their products are marketed either under the name Recknagel or Era-Tac.
Eliphalet Remington founded Remington arms in 1816 – he made a flintlock rifle with a firing mechanism. Their products, rifles model 700 and 870, are among the best selling firearms of all time. Remington is also known for producing more cartridges than any other company in the world. Remington arms, currently a part of the Freedom group, is known as America's oldest gun maker. Furthermore, they still manufacture their original product firearms.
Remington 7400, a modernized version of an earlier semi-automatic rifle, was produced from 1981 to 2004.

The rifle's receiver is drilled and tapped – there are two holes on each mounting surface.
Rifles Remington 7400/7600 and 750 have actions of the same dimensions, which is why they share the same mounts.

B: 52.3 mm
C: 15.24 mm
BHU: 0 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.
