PMC X-TAC 5.56 NATO 62gr LAP (Green Tip)

The PMC X-TAC 556K is PMC's take on the M855/SS109 green tip specification, delivering a 62-grain steel-core penetrator at 3,100 fps from a 20-inch barrel. Manufactured by Poongsan Corporation in South Korea, the same factory that produces ammunition for the South Korean military, the X-TAC line benefits from military-grade quality control applied to commercial production. The result is an M855-equivalent round with tighter lot-to-lot consistency than many surplus alternatives.

The 62-grain LAP (Light Armor Piercing) projectile features an SS109-style construction: a steel penetrator tip over a lead core in a copper jacket, identified by the green-painted tip. That puts it in the green-tip training lane rather than the plain-FMJ lane, and makes range rules especially important because many indoor ranges prohibit steel-core or steel-penetrator ammunition. From a 16-inch barrel, expect around 2,920 fps with 1,174 ft-lbs of energy at the muzzle.

PMC uses brass cases with Boxer primers, making the X-TAC green-tip load a straightforward range option for shooters whose ranges allow steel-penetrator projectiles. Compared with mixed-source surplus, a current commercial PMC SKU is easier to track by lot and product number.
