The RNVGA (also sometimes called the ARNVG) is the long awaited all-metal articulating night vision dual tube system housing produced by AB Night Vision. You can essentially think of this as an adaptation of the RNVG platform to meet modern requirements for articulating goggle designs in professional and commercial uses. 

All the same features found across the RNVG line -external LEMO power port, and 7075 aluminum and machined Delrin design for ultra-ruggedness -are still here. The RNVGA adds the benefits of individually stowable optic pods that automatically shut off power to the tube when rotated above 75 degrees, as well as user-adjustable tension on the pod rotation mechanism. Finally, onboard illuminator and push button operation, as well as single CR123 onboard battery compatible, also remain staple features of the RNVGA.
