ARES Defense Releases KeyMod Handguard for its MCR

MELBOURNE, Fla. ­ ARES Defense Systems, the country’s leading manufacturer of innovative, mission-configurable firearms, parts and accessories announces the immediate release and availability of KeyMod handguards for its patented MCR® weapons system.

Extruded from US-produced, aircraft quality aluminum alloys and machined to exacting tolerances, ARES’ new KeyMod style handguard provides customers with more options for customizing their premium MCR® rifle line, including mag-fed and belt-fed upper receiver assemblies.

ARES’ MCR® – Mission Configurable Rifle; an 8.5 lb weapon featuring gas piston operation, a 3-second quick change barrel system and the capability to feed from both linked ammunition belts and standard box magazines at operator discretion continues to evolve. “The MCR® has always been made available with a co-planer MIL-STD 1913 rail handguard, but as a premier rifle manufacturer we strive to meet customer expectations and not everyone wants a quad 1913 rail on their rifle anymore”, says Geoffrey Herring, President-CEO of ARES Defense. “Our new KeyMod style handguard answers that call so that shooters can position accessories exactly where they want them on the MCR®.”

As ARES Defense premier semi-auto rifle offering for the commercial marketplace, the ARES-15 MCR® vastly improves upon the standard AR15/M4 by offering exceptional flexibility with its dual-feed capability and quick-change barrel. This flexibility, combined with other unique features, allows users to instantly customize the MCR® without tools for virtually any use.

First in its class and setting it apart from other small arms systems, the standard magazine-fed ARES-15 MCR® is upgradeable to a dual-feed design with the simple installation of the optional Belt Feed Conversion Kit. The ARES-15 MCR® quick-change barrel allows users to configure the MCR® in seconds without the aid of tools and is available in 12″ (NFA Rules Apply) and 16″ inch lengths. Furthermore, the ARES-15 MCR® features gas-piston operation that provides greater reliability in extreme conditions, and is cleaner, cooler and more reliable in adverse conditions than the legacy direct-gas system.

The unique design of the MCR® also allows customers to upgrade their existing rifles by simply substituting an ARES supplied MCR® upper receiver assembly in place of the legacy upper, which are rearward compatible to the earliest AR15’s from the 1960’s.

  • kregano

    Man, this kind of looks like the godawful hand guard on the MPAR-556, but at least this one has a reason for being so huge. I wonder if it’ll mess up the balance like the MPAR hand guard.

  • TheNotoriousIUD

    Nice AR-47.

  • ManBear

    Does anyone make an IWB holster for this?

    • Budogunner

      Only MC Hammer and Psy can conceal carry this.

  • iksnilol

    Wait a second, Ares Defense and another belt fed upper?

    Yeah, this’ll end well.

  • Sianmink

    Wow that’s a remarkably ugly upper. I guess It makes up for that by being belt-fed though. Why is the foreend rail lifted to match the riser on the receiver?

    • iksnilol

      Maybe so that sights mounted on the front and rear rails can “cooperate”? Stuff like magnifiers or night vision.

      It would be stupid to not have them on the same plane in spite of looking ugly.

  • Dracon1201

    Is this rifle even going to be a thing for us dirty peasants, or is it just a plaything for our betters?

    • All the Raindrops

      It’s a retarded heap o fail

  • Beju

    I’ve always wanted a handguard to make my AR look more like the USS Sulaco…

  • Devil_Doc

    Sooo.. A hand guard for vaporware? Kel Tec should release a hand guard for the RFB..
