This HPA adapter represents the culmination of months of work to produce, from scratch, a shortened magazine for the GBB MAC11. This leads to an ultra lightweight magazine setup, that is both more enjoyable and economical than buying the gas mags.
A donor mag is required for exhaust valve and gas router.
There are a number of factors involved when designing a HPA adapter for this gun. We’ve taken the time to address these, ensuring flawless feeding, lifelong air-seal, and an excellent aesthetic. Feed lips which fix a few of the NS2 MAC11’s issues when feeding off AEG magazines have been included, along with a CNC machined valve insert.
Installation is simple, remove the valve from a MAC11 magazine, and install into the adapter (lube the valve to aid insertion). Then install our feed lips along with the gas router from your magazine.
