Melbourne, FL -(­­ ARES Defense Systems, the country’s leading manufacturer of innovative, mission-configurable firearms, parts and accessories announces that it is now shipping its patented MCR Sub-Carbine to the US commercial market.

ARES’ MCR Sub-Carbine is a lightweight, semi-auto 5.56 NATO caliber weapon featuring gas piston operation, a 3-second quick change barrel system and a left-side folding stock assembly that telescopes for adjusting the length of pull. The charging handle is ambidextrous and interchangeable with standard AR15/M4 charging handles to suit user preference.

Suppressor capable and able to be fired with the stock in any position, the MCR is a clear step above many of the folding stock and telescoping PDW options in the marketplace. Critical Sub-Carbine components are billet machined from aircraft grade alloys and heat treated to exacting specifications for durability and long weapon life. Aluminum components are Type III, Class 2 hard-coat anodized to MIL-A-8625F for maximum corrosion and wear protection. Furthermore, all ARES Defense products are 100% Made in U.S.A. with US materials and workmanship.

Also available to compliment the MCR Sub-Carbine is an optional SKB briefcase with custom-cut foam insert that holds the weapon, six 30-round magazines, a cleaning kit, Operator’s Manual and storage space for a suppressor or other Mission Critical Accessories. The MCR Sub-Carbine chassis is identical to the rest of the MCR family and can be reconfigured for belt-feed or other role by simply rearranging its parts.

“Overseas contracts with a NATO partner paved the way for the semi-auto MCR Sub-Carbine for the US consumer market,” says Geoffrey Herring, President-CEO of ARES Defense. “The Sub-Carbine is a critical model of the eight weapons that currently define the MCR family and is particularly significant for maximum portability. While all of the select-fire military models that we’ve shipped have featured our co-planar MIL-STD-1913 Picatinny Rail handguard, we recently added a KeyMod style handguard option for the US consumer market to meet the interests of our customers. The select-fire MCR Sub-Carbine is a proven and documented player in the military marketplace and is a serious system for professional shooters.”

The MCR quick-change barrel system 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. Additionally, the MCR Sub-Carbine 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 Sub-Carbine permits users to upgrade their existing rifles by simply substituting an ARES supplied MCR upper receiver assembly and folding stock mechanism in place of the legacy upper and stock, and the MCR is rearward compatible to the earliest AR15’s from the 1960’s.
