ERA-TAC picatinny rail - Remington 783 SA (20 MOA)

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.

20 MOA Inclination

20 MOA inclination is only needed when the scope runs out of elevation. For example, when shooting at the range of 100 m, shooter gains 58.2 cm / 100 m of additional elevation range with a 20 MOA mount. This is approximately 5.8 Mrad of elevation. To make things even clearer – if the target was placed at 100 m, the scope with 20 MOA inclined rail would aim to the center of the target while the rifle’s barrel would aim 58 cm higher than the scope. This gives the shooter extra elevation needed for long range shooting. If you plan to shoot on distances longer than 600 meters, use of rail with 20 MOA is greatly recommended. There is no negative effect of the inclined Picatinny rail in the mounting setup if you only shoot on shorter distances. The same goes also the other way around, since if you don’t shoot on extreme distances then Picatinny rail with inclination is not needed.

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.

Remington 783 is a bolt-action rifle that was launched in 2013. Its bolt locks into place with 2 locking lugs. The action is push-feed. Remington chambers 783 for .22-250 Rem., .223 Rem., .243 Win., .270 Win., .30-06 Sprg., .300 Win. Mag., .308 Win., 7mm Rem. Mag. and 7mm-08 Rem. The rifle features an adjustable Crossfire trigger (additional finger safety in the trigger blade). The barrel is free floated. For mounting purposes, there are four holes drilled and tapped on the receiver, two at the front and two at the rear. Standard models hold four rounds while magnum models hold three rounds. The small-sized ejection port adds to the rigidity of the action.

Remington 783 is available in two action lengths. When a rifle is available in more than one action length, only two-piece mounts are interchangeable between these rifles – a two-piece mount made for Remington 783 long-action (LA) can also be mounted on Remington 783 short-action (SA). One-piece mounts will only fit a rifle with a specific action length – a one-piece mount made for rifles Remington 783 long-action (LA) will not fit Remington 783 short-action (SA).

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.
