ASTKilo23 got the latest MOSFET releases from Perun Airsoft and he goes over the AB++ MOSFET in this video review... "Perun is a small Poland-based company that designed and creates mosfets for Airsoft guns. They were extremely kind in sending me several mosfets from their lineup to test out. The AB++ is an extremely well-built, compact mosfet that performs like a unit twice as expensive. Watch and see if this is the right mosfet for your next build."
