"Ordered this AGM M4 in December, took about a week or so to arrive. Our particular one did not have the "NATO" markings on the barrel, contacted ASMS, VP of operations was gracious enough to answer email personally, indicated that a select few of the 2010 enhanced versions did not have barrel markings, but still had the tight-bore barrel. Other than that minor and purely "cosmetic" issue, we are VERY pleased with this AEG, excellent quality, solid, it functions flawlessly and it shoots TSD .20g BBs @ over 410 fps. Comes with a good 8.4v 1200mah battery that gives a decent ROF, not fast but not too slow either, "clip the tabs" and this will hold a 9.6v mini or a 10.8v nunchuck battery. With the HOP-UP adjusted properly, it's a l-o-n-g range performer with decent accuracy. Easily upgraded. Thanks ASMS !!
