This is the not released yet version with extra cutouts and the Aluminum front site and barrel thread. Brand new and never used. It's the 185mm Version. This means you need to use 185mm inner barrels with this upper.
Ever wanted to use a CRBN Upper on an AEG gearbox? Now you can!
The new AirTac Customs AEG CRBN Upper receiver is made with genuine carbon fiber for strength and fits over ANY AEG Gearbox. This means you can use it with SSGs, DSGs, and even HPA drop-in engines!
Weighing in at only 105g, the AEG CRBN is 500% lighter than a stock SSG-1 Upper, making high-speed AEGs competitively viable in tournament play!
Equipped with dual hopup windows, integrated fiber-optic back and front sights, and compatibility with both G&G and Lancer Tactical lowers, the CRBN AEG is the ultimate speedsoft rifle upper.
