ALG Defense Ergonomic Modular Rail (EMR)

ALG Defense’s new Ergonomic Modular Rail (EMR) is set to make its debut at SHOT Show. This rail is lightweight, cost effective, absolutely loaded with smart features, and it will have a price that will turn the entire market on its ear.

ALG Defense EMR

The EMR more modular than your typical modular rail. Like most modular rails, it allows the user to place rail sections only where they want them. However, unlike most modular rail systems, the top rail is also removable! ALG Defense took care to ensure that when the top rail is removed, the shooter is left with a slightly raised, rounded tower that readily facilitates a variety of grips. All of the accessory rails thread into steel back plates for durability and can be attached at a variety of angles including a 45 degree offset.

The rail comes with an anodized aluminum barrel nut and the wrench necessary to install it. The EMR should be extremely rigid thanks to the way it screws directly to the barrel nut via 6 mounting bolts and its 1 piece, extruded aluminum construction.

The EMR includes a QD sling swivel socket so no additional sling mount will be necessary.

It will be available in 10″, 12″, and 13″ lengths with a hard anodized black finish and a gray finish as an option.

Here comes the “turn the market on its ear” part… The EMR is a complete rail system that includes everything, including the wrench, that you need to get up and running and it starts at just $135 retail!

ALG Defense AFM

ALG Defense AFMThere have been pictures circulated around the internet of a Glock 17 with with a couple of accessories that Geissele Automatics designed for a specific military unit, one of which was a magwell (SSD was the source of the images I saw). That magwell is now available through ALG Defense, Geissele Automatics’s sister company, and is called the AFM (ALG Flared Magwell). It features a flared opening to make inserted a magazine at speed more forgiving and an exterior ledge that helps redistribute recoil through the user’s lower hand.

You can call ALG Defense or use the worksheet on their site to order.
