The Quantum Industries Magnus Pro from 4UAD Smart Airsoft gets the attention of the Middle Aged Gamer... "This is the Quantum Industries Magnus Pro Hop Chamber and and Bucking upgrade video. As soon as this came out for pre order at Action Airsoft at the end of 2024 I had to get my pre order in and put it to the test. Quantum claim that this is their best Hop Camber yet especially when combined with their GBB Bucking. I Purchased this for my GHK URGI V3 GBBR, as we all know by now their V3 Hop Chamber is plastic and is crying out for an upgrade. So after testing for a few months this is what conclusion I came too."
