Phantom Defense 7.62mm NATO 175gr SMK NAS3 MK316 Mod 69 Rifle Ammo - 20 Rounds - The 175 gr 7.62x51 NATO Mk316 Mod 69 cartridge is a precision-engineered round designed for exceptional accuracy and reliable terminal performance. Featuring the renowned Sierra MatchKing projectile, this cartridge is a favorite among marksmen, military personnel, and long-range shooting enthusiasts. The Sierra MatchKing 175-grain bullet is celebrated for its superior ballistic performance, delivering consistent results with its high ballistic coefficient and meticulous design. At a muzzle velocity of 2,760 FPS, this round generates an impressive 2,961 ft-lbs of kinetic energy, ensuring maximum impact and precision over long distances. The MK316 Mod 0 cartridge is a U.S. military specification round designed to replace the legacy M118 and provide enhanced consistency in long-range engagements. Employing the 175-grain Sierra MatchKing HPBT projectile, it has earned a reputation as the designated precision solution for U.S. military snipers and designated marksmen. The forthcoming NAS3 variant of this loading (internally designated mod 69) represents a material leap forward. Our preliminary testing has produced velocity increases averaging 145 fps relative to the Federal contract version, while maintaining the same projectile weight and loading parameters. These increases translate directly into flatter trajectories, superior retained velocity at extended ranges, and reduced wind drift-factors of paramount in both military and precision shooting contexts. Flat Trajectory : The aerodynamic profile of the MatchKing bullet minimizes drag, maintaining stability and accuracy even at extended ranges.; Consistent Performance : Manufactured to stringent military specifications, the Mk316 Mod 0 ensures tight shot groupings and repeatable results in various environmental conditions.; Versatility: Ideal for long-range target shooting, competitive events, and tactical applications, this cartridge is effective in both semi-automatic and bolt-action platforms.;
