5.56 NATO 62gr Ammo for Military, Law Enforcement & Tactical Competition Use with Magpul D60 PMC X-TAC 5.56mm NATO 62gr FMJ ammo is manufactured in state-of-the-art facilities to meet the rigorous standards of military and law enforcement users. Like all PMC ammo, every round of X-TAC 5.56mm NATO 62gr FMJ is intensively inspected throughout the production process. This includes an electronic powder-check station that precisely measures the propellant charge in each round. If the propellant in any single X-TAC 5.56mm NATO 62gr FMJ cartridge varies by as little as 2/10 grain, that cartridge is rejected.
