Product Description
Hornady BLACK 5.56 NATO 75 Grain InterLock HD SBR ammunition is engineered specifically to deliver optimized performance from short-barreled rifles (SBRs) with 10.5"–11.5" barrels. Using proprietary propellant technology and a bullet design influenced by Critical Duty FlexLock technology, this load is built for consistent function and controllable performance in both suppressed and unsuppressed platforms.
