I DID read it, and I agree 100%. (Here's where I get myself in trouble

): MagPul makes aftermarket accessories.
The AR15 has been manufactured for decades and the specs should be so well-known, cussed and discussed, and just downright public knowledge that any company who makes mags for it should at least take the time to ensure that mags work in receivers that can have some variation in dimensions in non-critical areas. In short: I believe MagPul didn't do a thorough enough job in design and testing on the mags with the over-insertion tab. They evidently spec'ed them to fit Colt receivers and didn't allow for some variations among manufacturers.
