NORMA MLE 5.56×45 NATO – 70 GRAIN BARNES TSX | 20 ROUNDS
Engineered for uncompromising performance in the most demanding environments, NORMA MLE 5.56 NATO features the combat-proven 70 grain Barnes Triple Shock X (TSX) bullet — a 100% copper monolithic projectile renowned for exceptional accuracy, deep penetration, and devastating terminal effect.
Unlike bonded or jacketed bullets, the all-copper TSX expands reliably into four razor-sharp petals while retaining nearly 100% of its weight—even through barriers. Penetration is up to 28% deeper than traditional lead-core rounds, making it ideal for duty, defense, and field use where maximum effect on target is critical.
Each cartridge is precision-loaded into premium Norma brass for superb consistency, low flash, and reliable cycling in short-barreled carbines and full-length rifles alike. With a muzzle velocity of 2,793 fps and 1,212 ft-lbs of energy (tested from a 10.5” barrel), this is not your standard 5.56.
Lead-free, barrier-blind, and field-proven—Norma MLE 70gr TSX delivers duty-grade performance when it matters most.
