"This mid cap M4 mag is the cheapest one I could find on the market that actually performed pretty well. Of coarse it isnít supposed to be one of those great feeding mags the the PTS EPM 150 round mid caps, but it is decent quality. I use 2 of these mid caps for my Classic Army Skirmish CA4A1 EC2 M4 RIS Carbine while the rest are Lonex flash mags and a Classic Army High cap. This magazine has some wobble to it so I suggest you put one strip of electrical tape along the mag close to the top. When shooting with the mag it usually skips 2 to 3 rounds at times, but isnít too bad at feeding. If you have a low budget or donít want to spend a lot of money this is the mag to go.

Drop free because they arenít as snug as the stock magazine that came with my gun (pro or con)
