ERA-TAC picatinny rail - CZ 550/557 Product description

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

CZ stands for Ceská Zbrojovka. The company headquarters are based in Uhersky Brod, a small town in the Czech Republic. The present-day CZ was set-up in 1936 as a subsidiary of CZ Strakonice, which was, in turn, a subsidiary of Zbrojovka Brno – the armaments industry grew rapidly in the new Czechoslovakia at the time, and Uhersky Brod seemed like a great location since it was secluded and lay beyond the range of German bombers. In 1939, German forces occupied Czechoslovakia and the company was renamed to Böhmische Waffenwerke. Until 1945, they made machine guns LK-30 and MG-17 for the German army. After World War II, Russians gained control of the entire region and the company was nationalized by the communist government. Along with firearms, the company produced parts for the CZ 125 motorcycle and parts for sewing machines. In 1957, they started producing Model 58 assault rifle, a Czech version of AK-47. In 1961, the renowned Skorpion machine pistol entered production. The famous CZ 75 pistol was launched in 1975. Ceská Zbrojovka became an independent company in May 1992 when the “iron curtain” fell. Today, they are one of the biggest manufacturers light firearms. CZ 75, the famous pistol, is used as a basis by many other firearm manufacturers.

CZ 550, a bolt-action rifle, was first introduced in 1997 when it replaced CZ 537. It features a fixed magazine, but some models, chambered for .22-250 Rem., .243 Win. and .308 Win. can also come with a removable magazine. CZ 550 has an emergency gas pressure release valve on the right of the receiver. There are four locking lugs on the bolt. It has no mounting holes on the receiver; instead, the receiver is equipped with a 19mm dovetail for mounting purposes. CZ 550's action is controlled-feed. Safety catch is located on the right of the receiver, behind the bolt lever. CZ 550 rifles are chambered for .22-250 Rem., .243 Win., .308 Win., 6.5x55, .243 Win., .270 Win., 7x57, 7x64, .308 Win., .30-06 Sprg. and 9.3x62 (caliber range depends on the CZ 550 model). CZ 550 Magnum is chambered for 7mm Rem. Mag., .300 Win. Mag., .375 H&H, .416 Rem. Mag., .416 Rigby and .458 Win. Mag. CZ 550 Scandinavian is a little bit different from other CZ 550 rifles – it has a raised back to its stock. It also has no dove-tail on the receiver but 4 mounting holes, two at the front mounting surface and two at the rear mounting surface.

This mount is made for all CZ 550 rifles with standard action length (it is not suitable for CZ 550 Scandinavian and Magnum versions) and Brno ZKK 600.

Rifles CZ 550, CZ 537, CZ 557, Brno ZKK 600, Brno ZKK 601, Brno ZKK 602 and Brunner 19 have have a 19mm dovetail on the receiver for mounting purposes.

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.

Top-Notch!

I highly recommend Optics Trade EU, top-notch service, lightning fast delivery via “Express Mail Service-mounts”. Will buy again.<br><br>The product: Typical Recknagel, perfect fit and function, no complaints, very good value for the price. <br><br>Regarding CZ clamp-on mounting rails, I think the Recknagel version having the positioning/locking lug incorporated into the loose clamp would allow for some possible tolerance compensation if needed, resulting in basically stress-free mounting of the rail when the bolts are torqued. <br><br>Bolts are M4 10.9 (Recknagel Information), could be torqued up to 4 Nm. I use 3 Nm, lightly oiled, works.<br><br>User-5

by Optics Trade team

So if I'm reading the specs correctly, this 550 picatinny rail will fit properly on my new CZ 557 ? Thx

by glen

This Picatinny rail will fit on CZ 557 if the caliber is .30-06 or similar.

It will not fit on CZ 557 in .308 Win or .243 Win, since CZ 557 in these two calibers features medium-length action.
