I read Ezell's book, he said there were quality control problems with the M-14 which apparently were never resolved, also the initial concept was flawed, IMHO-the M-14 was supposed to replace the M-1 Rifle AND the BAR. A 9 pound rifle firing a full power cartridge in a fully automatic mode, right. There was supposed to have been an M-15, a heavy barreled M-14 for the BAR role, it never went into production. There was an M-14E2 for the BAR role, the people I knew who fired one said it was unsatisfactory, too light. That said, I trained in BCT on the M-14, prefer it to the M-16. In Vietnam it seemed the only real function of M-16 armed riflemen were to point out targets to M-60 gunners. The problems with the M-16 jamming due to the use of different powders wouldn't have occured with the M-14 with its user cleanable gas system. The 7.62 round is effective not only on personnel but on thin skinned vehicles and on aircraft within range, the 5.56 round is not. They're constantly tinkering with the 5.56 round and its platform as combat exposes its shortcomings. "Someday" I will get an M1A, if someone gives me an AR-15 or ine of its clones I will acept, but I will not buy one.
