ERA-TAC picatinny rail - Remington 870 TAC

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

Remington Arms was founded in 1816 when Eliphalet Remington made a flintlock rifle with a firing mechanism. Remington is possibly the oldest gun maker in America that still produces its original product guns. They produce firearms, ammunition and other accessories. Remington model 700 and model 870 are among the best selling firearms of all time. The company is also known for the development of more cartridges than any other company in the world.

Model 870 Remington, a pump-action rifle, was first introduced in 1950 – it replaced the earlier Model 31. The first two versions introduced were Wingmaster and Trap (later, Express and SPS were launched). All of these versions were upgraded throughout the years. Wingmaster, for example, was succeeded by Wingmaster Light Contour and by Super Magnum version in 2000. Wingmaster is still manufactured today after 60 years, proving that it is truly a great piece of work – many modern pump-action rifles are still based on Model 870. It is – without a doubt – an American icon.

This mount is suitable for Remington 870 TAC, a very compact pump-action shotgun (available in 12 gauge or 20 gauge).

Remington model 870 TAC does not have holes drilled and tapped on its receiver for mounting purposes. To mount this Picatinny rail on Model 870 TAC, a gunsmith has to drill the holes on the receiver according to the dimensions of holes on the Picatinny rail.

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

The product has a warranty period of 10 years.
