- High-density polymer build
- Takes M4 / AR-15 AEG magazines
- For KWA / ASG MAC-11 GBB SMG
If you're a fan of the MAC-11 but wish it were a more effective primary, the Airtac HPA Adapter for MAC-11 GBB; M4/AR-15 AEG Mags is the key! Designed for GBB MAC-11 SMGs by KWA (NS2 System), KSC (System 7) and ASG, this adapter is designed for US-spec HPA setup and feeds from standard M4/AR-15 AEG mid-cap magazines, working at its best with PTS EPM 1-RX mags.
HPA eliminates FPS fluctuation due to the "cooldown" effect, resulting in improved shot-to-shot consistency and improved accuracy down range, especially under rapid fire. It also enhances cold-weather performance, meaning you can still run your machine pistol in winter, when all the green gas-fuelled MAC-11s are in hibernation.
This adapter also adds a lot of extra capacity to a MAC-11 setup compared to its original 42-round mag, meaning you can keep heads down with its stunning rate of fire without worrying about reloading 2 seconds after the trigger is pulled.
