Shell Shock Technologies, LLC. (SST), a leading innovator in the ammunition industry, today announced that its highly sought-after 5.56x45mm NAS3™ Cartridge Cases are back in stock and available now.

Engineered from a high-strength nickel alloy, NAS3 cases are a proven choice for precision shooters, competitive marksmen, and high-volume handloaders who demand consistency and reliability. Unlike traditional brass cases, NAS3 cases are up to 50 percent lighter, reducing overall load weight for enhanced mobility and convenience, and deliver superior performance at standard SAAMI pressures, achieving higher velocities through increased internal case volume that enables more efficient powder ignition.
“We know our customers have been eagerly waiting for the 5.56x45mm NAS3 cases to return, and we’re thrilled to bring them back alongside a meaningful offer for the handloading community. Our NAS3 cases represent a genuine advancement over brass; lighter, more durable, and engineered to perform. This sale is our way of welcoming shooters back to the future of ammunition technology,” Peter Foss, Managing Partner and CEO of Shell Shock Technologies.
Constructed from high-strength nickel alloy, NAS3 cases offer exceptional corrosion resistance, tensile strength, and elasticity for long-lasting reliability. Designed with superior lubricity to prevent abrasion, fouling, and damage to firearm breech and ejector mechanisms, the NAS3 cases help prolong firearm life. The cases will not split, ship, crack, or stretch. High tensile strength reduces crimping effort while enabling precise bullet seating, simplifying the reloading process, and is optimized for small rifle primers. The 5.56x45mm NAS3™ Cartridge Cases can be effortlessly collected with a magnet after ejection for fast and efficient range cleanup.
Available in packs from 250 to 10,000 cases. Shell Shock Technologies’ 5.56x45mm NAS3™ Cartridge Cases are now back in stock. Visit www.shellshocktechnologies.com to place your order using code 556ISBACKIN to save eight percent on your order of $300 or more from April 12 – 19, 2026.
