WE MP5 to MP5 AEG HPA Adapter - 2026 Edition - PLUG AND PLAY
Choose options
Updated 2026 edition with high quality CNC MP5 magwell
Love your WE GBBR mp5, hate gassing out and low capacity?
Well we’ve reverse engineered & manufactured our own short magazine, then added an MP5 magwell for the perfect skirmish build. With the short 65 round magazines theres almost no size difference between this and the original magazines.
Plug and Play - This adapter comes with feed lip, gas router and valve prefitted so you don't need to take parts from a donor mag!
The MP5 magwell has a rear shim held in by two screws. This can be removed to allow fitment of curved CYMA MP5 mid-caps. Leave it in place for straight MP5 mid caps.
DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT OUR EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT OUR EQUIPMENT TO A TIPPMAN STYLE HPA LINE
