ALG DEFENSE - ERGONOMIC MODULAR RAILS - PRODUCT INSTALLATION VIDEO

An Introduction To Our Ergonomic Modular Rails

1. ERGONOMIC
Instead of four sharp and jagged M1913 rails spaced at 90 degree intervals, like a traditional quadrail, the ALG EMR is fully ergonomic, maintaining a comfortable rounded shape throughout the length of the rail. The V0, V1, and V2 have a rounded top allows the shooter to easily wrap his or her thumb over the top of the EMR as many shooters like to do with a forward grip.

2. SET-UP IS MODULAR AND FLEXIBLE
V0 and V1 Accessory rails can be attached anywhere along the length of the rail in 45° intervals, including the standard 12, 3, 6 and 9 o’clock positions.
V2 and V3 Accessory rails can be attached anywhere along the length at 60° intervals. The V2 provides a machined picatinny rail section at the fore end of the rail at the 12 o’clock position. The V3 provides a full-length M1913 picatinny rail at the 12 o’clock position.

3. FREE FLOATING
The weapon barrel is completely free floating when an ALG EMR is mounted. No force is put into the barrel from slings or bipods that could affect point of aim.

4. STRONG
The ALG EMR is machined from a 6061-T6 extrusion, made from aircraft grade aluminum.

5. RIGID
Current infantry doctrine makes extensive use of accessories that require attachment to a weapon rail. Flashlights, visible and infrared lasers, night vision and thermal sights, all require a rigid weapon rail so that zero is not changed when a bipod or sling is used to support the weapon from the rail. The ALG EMR is a rigid interface for weapon accessories due to its precisely machined proprietary barrel nut and secure rail interface and clamping arrangement.

6. LIGHTWEIGHT
Use of extruded 6061-T6 aircraft grade aluminum in an ALG EMR give the entire assembly a good strength and performance to weight ratio.

7. ACCESSORY RAILS EASY TO INSTALL
The V0 accessory rails are fastened to steel slide nuts and are fully captured in channels configured in the rail ID. Slide nuts are much more soldier proof than inserts as a cross threaded screw can easily be repaired with the replacement of a slide nut. It takes literally seconds to install or remove an accessory rail without standing on your head to deal with non-captured plate nuts.

8. ACCESSORY RAILS ARE SECURELY ATTACHED
The ALG EMR V0 accessory rails are designed to securely attach to the rail with the supplied steel slide nuts. The slide nuts take the place of individual nuts which are difficult to tighten and maneuver inside the rail. By screwing the accessory rail screws directly into steel and not the aluminum rail, the attachment method is strong and vibration resistant. Ergonomic Modular Rails are also available with M-LOK configurations (V1, V2, and V3), which allow the direct attachments of third party accessories, taking advantage of the rock solid M-LOK design.

9. RAIL ASSEMBLY IS EASY TO INSTALL
Each ALG EMR comes with a precision machined, 2” long barrel nut that is machined from aircraft grade 7075-T6 aluminum and hardcoat anodized for a durable surface. Also included is the proprietary ALG EMR barrel nut wrench which is used to tighten the barrel nut to the upper receiver. The ALG EMR barrel nut is required to be indexed to the gas tube, and includes all of the necessary shim kits and instructions to do so. Then the rail is slid onto the barrel nut with a fit that precisely aligns the rail to the barrel. After indexing the rail to the receiver, six mounting bolts are tightened and the rail is secure.

10. RAIL IS EASY TO REMOVE
Just by removing six screws the ALG EMR can be slid off the barrel nut for cleaning or gas system maintenance. As quick as it is removed the ALG EMR is can be re-installed with the precise barrel nut to rail fit maintaining sight and accessory zero.
