Krytac 150rd M4 Mid-Cap Magazine (Color: Black)

"These mags are golden most of the time they feed ALL of the BB's even the last few rounds, that never happened with the matrix mags that I have those are junk. I was worried at first seeing reviews about these mags not feeding .30's or .32's i'm not sure what they're talking about I don't use .32's in my krytac m4 but I tested them out in the mag anyways and didn't have any issues at all. So if that worried you too don't worry and just buy them they're great.

"I was an EPM fan boy but these mags are AMAZING! ZERO feed issues ZERO mag issues unlike EPM. I sold all my EPMs and converted to these.

"Best mag I've used so far. I prefer this mag over the EPMs. For $16 it is a little on the pricier side but the quality is undeniable. The outer shell is very thick and durable nylon fiber polymer, similar to the polymer on some high end AEG's. I dropped it from 4 feet onto hard laminate floor twice and there wasn't even a scratch. The window that shows when you're low on BBs is very handy. There is also a window on top to let you know when you're at almost maximum capacity as you're feeding BBs into it. It feeds cleanly and smoothly. I haven't tested it in a high RPS gun but on my 20-25 RPS guns it feeds 0.30's perfectly fine, never jammed, never double fed (some inferior mags can put so much pressure on the BBs that the BBs are crushed/deformed or double feed with no hop). It is a little bit thicker than the EPM's so it may have a slightly tighter fit in some magwells, which I like because the EPMs can wobble sometimes. I don't see a reason to use the EPMs over this mag other than the fact that EPMs can accept magpuls and look a little bit nicer with the fake bullets.
