An improvement upon our Gen 1 AK HPA Adapter Lower, this adds a paddle style magazine catch and BB retention to reduce BB loss when changing magazines. This is compatible with all our AK to AK AEG HPA Adapters (e.g. TM AKM, WE AK, GHK AK).

It is compatible with CYMA Midcaps, Drums, and LCT AK Drums
