The TEC-GIII rises to meet the demands of both enthusiasts and professionals by integrating the proven functionality
of G3 magazines with the familiar and trusted components of the AR10 platform.
Featuring a Direct Impingement (DI) system, the TEC-GIII is available with a choice of barrel lengths: a
16-inch option chambered in .308/7.62 NATO with a 1:10 twist for balanced maneuverability, or a 20-
inch variant with a 1:8 twist chambered in 6.5 Creedmoor for long-range precision. The rifle’s receivers
are precision-machined from Billet T6 Aircraft Aluminum, ensuring a solid foundation for sustained
durability. An adjustable gas block enables the rifle to be tuned for suppressor use, while the controls
adhere to the standard safe and semi-automatic settings for user familiarity.
The TEC-GIII caters to operator comfort with a Mil-Spec buffer tube, a Magpul Fixed Stock and CA-grip. A 15-inch M-LOK handguard, featuring an integrated MIL-1913 Rail, offers ample space for accessories. The rifle’s balance is optimized with a weight of 8.5lbs and an adjustable overall length from 35 to 39 inches, providing a comfortable and adaptable shooting platform. Additionally, the TEC-GIII is fitted with a Nickel Boron Trigger for a smooth,
consistent pull and a Muzzle Brake.
