HK Army – 170R

HK Army Custom Designed and Machined Planet Eclipse 170R

The beating heart of every GTEK marker is the incredible Gamma Core. A revolutionary spool valve design that uses Breech Sensing Technology and a unique pneumatically latching spool to accurately control the exact amount of air released for each shot completely independently of the solenoid and the dwell time. This makes it highly efficient without the need for any electronic adjustment or tuning as well as making it supremely reliable in playing conditions ranging from -20f to +100f. In order to be able to shoot the most fragile paint possible, the Gamma Core employs a very finely controlled 3-stage bolt acceleration profile to gently pick up the ball and push it into the barrel. The gas release for the firing pulse is also carefully tailored to maintain low peak pressure behind the ball which gives the GTEK 170R its distinctively quiet shot and smooth feel.

The Gtek170R’s hoseless and toolless design gives the player more freedom and enables quick and easy access to batteries and the breech sensor.

The slick blade trigger provides the player with 4 levels of trigger adjustment.

Powered by the ground-breaking gamma core drivetrain, the Gtek170R can go toe-to-toe with any opponent on any battlefield in any weather without breaking a sweat.
