Built for the 5.56 NATO / .223 Remington Platform

Optimized specifically for the 5.56 NATO and .223 Remington chamberings common in AR-15, M4, and similar modern sporting rifles, these NAS3 Cartridge Cases from Shell Shock Technologies combine a high-performance nickel alloy body with a rugged stainless steel head. This innovative two-piece construction sets them apart from traditional brass, giving you a lighter, stronger foundation for your custom loads.

Key Advantages of Shell Shock 556 NAS3 Primed Cases

• Up to 50% Lighter Than Brass: Reduce the weight of your loaded ammunition without sacrificing strength. Carry more rounds during extended range sessions, tactical training, or backcountry varmint hunts.
• Superior Strength and Elasticity: Twice the tensile strength of brass with greater elasticity, these cases handle pressures reliably and spring back consistently for dependable performance shot after shot.
• Exceptional Corrosion Resistance: Built to perform in harsh environments—rain, snow, humidity, sweat, or extended storage—without the pitting or degradation common to brass.
• Enhanced Lubricity and Smooth Operation: Won’t abrade, clog, or foul your firearm’s breach, extractor, or ejector mechanisms. Expect cleaner cycling and flawless extraction even during rapid fire strings.
• Uniform Dimensions and Precision: Meticulous engineering ensures consistent wall thickness and exact specs, translating to tighter velocity spreads and improved accuracy for match-grade results.
• Cooler Ejection and Magnetic Pickup: Cases eject noticeably cooler to the touch and are easily retrieved with a magnet, making high-volume range cleanup faster and safer.
• Factory Primed for Convenience: Skip the priming step entirely and move straight to charging and seating your favorite projectiles—from lightweight 55gr FMJ for high-volume training to 77gr match bullets for precision work or specialized tactical loads. Perfect for shooters who value more time on the range than at the bench.
