I knew it! Mags are all the rage right now... especially pneumags. I don't care for the aesthetics of several of the parts, but as a whole, that thing is astounding! Of course, the UMF steals the show. I'd love to have one on my yet future mag. The only thing I'd change is the location of the lpr. I like the ones mounted to the front of the vert asa, and perhaps a different foregrip. Looks good!
