EAW Steel Picatinny rail, Browning Acera (20 MOA)

About Picatinny Rail

The Picatinny rail system is engineered with slots spaced precisely 5.23 mm apart, ensuring consistent and versatile usage along its entire length. This design allows for easy mounting and universal compatibility, meaning accessories designed for a Picatinny rail will fit perfectly, regardless of the manufacturer or production date. Valued for its affordability, durability, and reliability, the Picatinny rail has become a preferred choice among professionals and military personnel, dominating the scope mounts market in recent years.

The Picatinny design represents a significant improvement over the older Weaver standard. While the Weaver system has only a few predetermined slots, the Picatinny rail features continuous slots across its surface, offering greater flexibility for mounting devices at any location. Additionally, the slots on a Weaver rail are narrower, at 3.8 mm, which means scope mounts designed for Weaver rails can fit on a Picatinny rail. However, mounts specifically made for Picatinny rails do not fit on Weaver rails due to the size difference of recoil stoppers. This compatibility and versatility position the Picatinny rail as a superior mounting solution for various applications.

About the FN Browning

Browning Arms Company was founded in 1880 by the prolific inventor John Moses Browning in Ogden, Utah. The company's innovative designs were produced by major manufacturers including Winchester, Colt, and Fabrique Nationale of Belgium. Known for a variety of firearms like the Colt Peacemaker and Browning automatic rifles, Browning also diversified into non-firearm products such as knives and clothing. In 1977, it was purchased by the Belgian firm Fabrique Nationale and remains influential in the firearms industry.

About the Acera

The Browning Acera is a straight-pull centerfire hunting rifle introduced in 1999 as a modified repeatable version of the BAR rifle. The receiver, which is drilled and tapped for optics mounts, is made of aluminum alloy. This model does not feature a gas system or return spring; instead, the bolt must be pushed back manually, with the bolt handle positioned further forward compared to most straight-pull rifles. The bolt features seven locking lugs, and the removable magazine is of the drop-down type. The Browning Acera has four holes on the receiver for mounting purposes. This model was discontinued in 2001.

• 7mm Rem. Mag.
• .308 Win.
• .30-06 Spr.

• 9.3x62

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, 20 MOA is most common. 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.

Design of the Rail

The EAW Steel Picatinny rail, Browning Acera (20 MOA), is crafted from steel, providing exceptional hardness and durability compared to aluminum. This ensures a higher degree of repeatability with minimal wear over time. The rail features 13 slots and 4 mounting holes, all secured with 6-48 threading. A unique central channel allows the simultaneous use of the rifle's iron sights, providing a reliable backup option without needing to remove the rail when there is nothing mounted on it. This Picatinny rail is firmly attached to the rifle with 4 screws, ensuring a secure and stable mount.

Usually, a Picatinny rail can be mounted on multiple different rifles if they share the same mounting surface, which we commonly refer to as the mounting standard. The EAW Steel Picatinny rail, Browning Acera (20 MOA) can be mounted on the following rifles, which share the same mounting standard:

• FN Browning BPR
• Benelli ARGO
• Benelli R1
• Fabarm Iris
• FN Browning BAR
• FN Browning BAR MK2
• FN Browning BAR MK3
• FN Browning Maral
• FN Browning BLR LA
• FN Browning BLR Lightning LA
• Winchester SXR Vulcan

Mounting Instructions

Clean the rifle's receiver thoroughly with a cleaning fluid, such as acetone, to remove all stains, grease, and oil. Once the surface is clean and dry, verify that the screws fit both the rail and the receiver holes. Before mounting the rail, apply a minimal amount of thread-locking fluid (278 or 648) to the screws, avoiding any contact with the mounting holes. Carefully clean any excess fluid around the rail using the cleaning fluid. Using a torque driver, tighten the screws to the appropriate torque (up to 3 Nm/26.5 in-lbs). If you require any mounting tools, you can find them on our Rifle Scope Mounting Tools page.
