| Umarex G36 AEG | Direct Native Fit | Purpose-built for the Umarex G36 AEG magazine well and feed geometry. Seat the adapter fully until it locks against the magazine catch, then verify the feed lips align cleanly with the BB feed path for consistent, uninterrupted feeding. |
Select your adapter type from the drop-down. M4, MP5 and ARP9 options accept the corresponding magazine pattern; Shotgun Shell and Ambi Angled M4 are extended-profile options; drum options are complete drum assemblies.
