I never said it was, but everything I've stated is researchable.
I, reluctantly, went back to Vickers' site, and I found nothing related to his "technical" credability. Did I miss it? Can you show me where it is?
Also, He calls himself "the father of the Hk 416." Other sparse and vague phrases on his own website, and hkpro, I don't see any factual information that states exactly his involvment in any part of the design process. If you believe that, I urge you to believe that I'm the "father of the refrigerator." The father of the Hk 416 is Eugene Stoner. Some German mechanical engineer tweaked an old piston design and Hk decided to mill out parts instead of casting, and everyone wants to act like they reinvented the wheel? Please! I love Hks. I have one, and I've actually handled a 416 (not the MR556). While robust, it's not superior. I'd bet the German mechanical engineer at Hk has never even heard of Larry Vickers. Now back to the magazine issue:
I'm too lazy to find it to quote, but someone replied that the USGI 30 round magazines are actually designed to hold 28. THAT'S THE BIGGEST LOAD OF CRAP I'VE READ YET!! You show me where, in ANY firearms manual, the manufacturer suggests this, and I will gladly apologize for calling you an idiot. I certainly never came across that sentence in any firearms manual I've ever seen.
I give up. Everyone believe whatever you want. If you want the truth, demand it be backed by experiment and factual data.
