Yeah...

Mags are feeding into the chamber, but that's as far as it goes. Either they jam, or practically have no velocity. I have an Echo1 ER25K, and there's even an Echo1 tech video on how to install that hop up unit... I REALLY doubt they would promote a unit that isn't compatible. What do I need to do to get this working? I use a KWA 2g bucking and normal nub, with a 6.03 509mm barrel.
