- great mag
I bought this mag because the mag that came with my echo1 mp5-j broke in the first 2 hrs. This was probably my fault because I didn't buy it from shorty. ANYWAY so I got this mag today and it fits fine in my mp5-j and doesn't misfeed at all! It's great and the first time i loaded it up i released them all and counted to see how many it really holds. It holds between 96 and 97 which is good considering there are other 10 dollar mags on this site that only hold 90 and some reviews say they don't fit in echo 1s. I wish I bought 2! My advice is if you need a mid cap mag for any echo1 mp5 BUY THIS ONE!
