Frontier Cartridge 300 Blackout ammunition delivers consistent performance for AR-15 platform rifles chambered in 300 BLK. Loaded with 125-grain full metal jacket bullets, this supersonic load offers reliable cycling and clean, predictable terminal performance for training and range work. Manufactured at the Lake City Army Ammunition Plant, Frontier ammunition uses military-grade components and quality control standards adapted for the civilian market.
Compatible with both semi-automatic and bolt-action firearms chambered in 300 Blackout, this load uses boxer-primed brass cases suitable for reloading. Available in 20-round boxes. This is a supersonic load — not optimized for suppressed use. For subsonic shooting, select a heavier bullet weight (typically 190–220 grains).
