George McKnight (verified owner) –
This is both a review and a tip.
This FX Impact High Capacity M4 Magazine Design works a treat in my M3, running .25 pellets, just the quality you’d expect from FX.
The tip is…don’t buy cheap! I purchased a 3D printed one off the most well know and popular auction site, and although it works perfectly fine with the JSB King Heavy in 33.95gr, it won’t handle the H&N Baracuda 30.86gr, and the reason is that the pellet is slightly longer in length and will not load into the 3D mag. So the tip is, if you want to save money buy the real deal
