Seat the adapter fully and confirm a positive seal against the loading nozzle for maximum gas efficiency and consistent feeding, without introducing drag on the reciprocating assembly. |
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; HPA Drum and Green Gas Drum are complete drum assemblies.
