ERA-TAC picatinny rail steel - Mauser M12

Introduction

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.

About the rifle

Mauser is a German arms manufacturer of semi-automatic pistols and bolt-action rifles. It was originally founded as Königliche Waffen Schmieden in 1811. Their designs reached high popularity and their products were exported to a number of countries. Because of their success, many other manufacturers used a similar design.

Mauser M12 is a bolt-action rifle. Its push-feed action, which is round-shaped, is same as the one Mauser 98 is equipped with as regards dimensions. The rifle is basically a combination of old-style exterior and innovative interior. There are 6 locking lugs on the bolt which the user operates with a 60-degree lift. M12 features 3-position safety SRS and a detachable zigzag magazine with 5 cartridge capacity while the magnum model's magazine holds 6 cartridges. Standard version, which has barrel length of 22'', is chambered for: .22-250 Rem., .243 Win., .308 Win., 6.5x55, .270 Win, 7x64, .30-06 Sprg., 8x57 IS and 9.3x62. Magnum version has a barrel length of 24½" and is made for these calibers: 7 mm Rem. Mag., .300 Win. Mag. and .338 Win. Mag.

Mauser M12's action is of the same dimensions as Mauser K98, which is why these two rifles share the same mounts.

Mounting instructions

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.

Warranty
