NGT-TX Gamma Tool
NGT-TX
1.36″ OD Gamma Tools
The NGT-TX gamma tool is a shorter version of the NGT-T tool. 2.0” have been removed from the electronics chassis for an overall make-up length of 11.6”. All other specifications are the same as the NGT-T.
To protect your gamma investment and ensure the best performance use CBG original SNB Snubbers-Shock & Vibration Isolators.
