The ARES AAR (above) offers users a handy and compact CQB carbine in 5.56mm. The ARES DMR (above, right) takes the same basic platform and modifies it to fulfill a role as a high-volume sniper rifle also in 5.56mm.

In 1998, a young small-arms designer named Geoffrey Herring conceived a completely new approach for converting the M16 rifle into both a successful and viable squad-support weapon. Unlike previous attempts, Herring’s design would totally eliminate the entire M16 upper receiver component, leaving the stock lower receiver group to host the new mechanism. Using the standard lower-receiver group allowed the same serial number to remain intact and more, the fire controls.

Called the SHRIKE 5.56, the weapon is manufactured by ARES Defense Systems and is a radical departure from all previous designs. Rather, it is manufactured as a complete, dedicated weapon or as an upper receiver conversion assembly, which is compatible with any standard M16 or M4 lower receiver.

Operated by a short-stroke gas piston, the ARES SHRIKE 5.56 uses an impinging piston in an adjustable gas cylinder mounted on the left side of a quick-change barrel. Mounting the in-line piston/operating rod on the side was done for the same reason as in the Stoner and allows the weapon to use an improved top-mounted version of the original quick-change barrel system found in the famous Stoner 63/63A Weapon System. However, in the ARES, with the side-mounted gas system, totally modularity is achieved without having to rotate the receiver upside down.
Besides being one of the fastest barrel-change systems, this one uses a spring-loaded vertical tapered pin that enters through the top of the barrel extension to center and anchor the barrel in position, but that’s not all. If there were a catastrophic case failure, gas escaping into the barrel extension would take the easy way out, forcing the spring-loaded barrel retaining upward to vent gasses up ahead of the receiver.

The ARES SHRIKE 5.56 normally fires from a closed multi-lugged bolt, but can also be had with an open-bolt module that simply replaces the standard closed-bolt components. Several lengths and weights of barrels are available, along with a rigid MIL-STD-1913 rail handguard the front of which houses a precise fitting bulkhead to support the front of the quick-change barrel similar to the barrel extension of the .50 caliber M2HB machine-gun. The front sight is mounted on top of the gas block.

On the left side of the ARES upper receiver is the non-reciprocating charging handle, which can be folded when not in use. Because of the placement of this, the top portion of the bolt release is removed, the only modification necessary to the M16’s lower receiver group. This necessitates pulling the charging handle to the rear and releasing it to allow the bolt group to go forward. This is not only a better way to charge the M16, but the modification also eliminates the danger of the bolt release being bumped to unintentionally release a “locked-back” bolt group.

  • what im implying is to make a little modification of the AR-1o lower receiver

  • I want Ares Defense to develop a 7X46 caliber assault machine gun variant of the SHRIKE Advance Weapon System with 18 inch barrel. The barrel is made of 41V45 steel with polygonal rifling cold hammered forged barrel. The lower receiver is from AR-10 with little upgrading to fit the 7X46 murray cartridge

  • its be much nicer if it in caliber 6.8SPC, 6X45mm and in 7X46 murray with a 16.5 inch barrel the murray 7X46mm the lower receiver is from the AR-10 lower receiver with 16.5 inch barrel how about that ARES Defense Systems can you do it?
