Ensuring the durability of the AR-10 platform both the upper and lower receiver are constructed from Billet T6 aircraft-grade aluminum. Providing comfort and customization is a Mil-Spec buffer tube and 6-position adjustable CCS Carbine Stock. Likewise, the interface between man and machine is a THRIL RTG pistol grip and 15-inch M-LOK handguard. Running the entire length of the upper and handguard is a Picatinny rail for attaching optics and accessories.

Within the handguard is a 16-inch barrel chambered in .308/7.62 NATO with a 1:10 twist or a 20-inch barrel chambered in 6.5 Creedmoor with a 1:8 twist. The barrel also features 5/8×24 muzzle threads for affixing a suppressor and ships with an attached birdcage flash hider. Correspondingly, an adjustable gas block caters to the use of a suppressor.

In addition, the bolt carrier group (BCG) is specifically designed for use with G3 metal magazines. Likewise, the rifle ships with three German made G3 magazines. The upper receiver also comes with a cam-pin wear plate to protect it from cam-pin wear.

Measuring 35 to 39 inches and weighing 8.5 pounds, the TEC-GIII is available in either black or FDE TYPE III Hard Coat Anodized finish.
