Magazines to suit WE TECH HI CAPA GBB Pistol
For best storage, we recommend storing the magazine with either maintenance storage gas or a very small fill of GG to ensure the mag has GG in it not air, air will dry out the internal seals and cause leakages.
For best performance always purge out the air from the magazine on first fill or every fill where the magazine has run completely empty. For more info watch this video:
