Well, fitment of the green labels are hit/miss. Sometimes you have to shim the magwell, or file down the lip, or whatever; sometimes you don't. Really depends on the tolerances/dimensions of the gun.
Same applies to the Magpul mags - my SR25 mags only come in PTS variety (no green labels), but they didn't fit or run smoothly out of the box. They needed serious shots of silly oil and some smoothing of the tracks, and the mag catch needed modifications to actually get the mag to catch and hold - otherwise I could just pull them out without even touching the mag release. Again, it boils down to the tolerances of the gun.
Still, I like both - they both have their place.
