ERA-TAC picatinny rail - Haenel SLB 2000+

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 aluminium (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

Heckler & Koch, a firearms manufacturing company, was established in Germany. For years, they have been cooperating with police, security forces, and NATO. They manufacture assault rifles, precision rifles, machine guns, pistols etc. The company is known for the development of polygonal rifling and use of polymers in weapon designs.

As the name suggests, Heckler & Koch SLB 2000 was introduced at the turn of the millennium. SLB stands for Self-Loading Rifle. It features a modular design, typical for many arms produced by H&K. The weapon can feature a detachable magazine or internal 2, 5 or 10 shot magazine. It can be chambered for the following calibers: 6.5x 55, 7x64, .308 Win., .30.06 Spr., .300 Win. Mag., 8x57 and 9.3x62. There are two mounting holes on the front surface and three mounting holes on the back surface.

Heckler & Koch sold the design to Haenel. Shortly after, Haenel SLB 2000+ was released. The rifle is practically the same as H&K's original version, which is why mounts made for H&K SLB 2000 will also fit Haenel SLB 2000+.

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.
