Doesnt stay in place - Lockstep Arms PMAG GEN M3 AR15 Base Plate Ranger +0-Round

The major problem with this is that it often comes off by itself. The locking mechanism is way too weak. I would be shooting at the range, then all of a sudden my mag spring just drops. The color is also off. Its like a dlc black that doesnt match the pmag color. At least coat it matte black so it doesnt stick out like a sore thumb.
