Frontier 300 Blackout 125gr Fmj 20/2

Frontier 300 Blackout 125gr FMJ 20/2 ammunition delivers consistent, dependable performance for suppressed rifle applications, subsonic training, and intermediate-distance shooting. Manufactured by Frontier Cartridge, this 20-round per box loading pairs a 125-grain full metal jacket projectile with a muzzle velocity of 2,175 feet per second, making it well-suited for both short-barreled rifle (SBR) platforms and standard 300 Blackout rifles where ballistic performance and ammunition compatibility are critical.

The 300 Blackout cartridge was purpose-designed for suppressed fire and subsonic applications, and the 125-grain projectile weight sits in the optimal range for this caliber. At 2,175 feet per second, this loading provides reliable cycling in both suppressed and unsuppressed platforms while maintaining the ballistic characteristics that make 300 Blackout distinct from 5.56 NATO. Full metal jacket construction ensures consistent feeding through magazine-fed rifles and minimizes fouling, making this round practical for high-volume training and range sessions. The 20-round box format allows operators and shooters to stock multiple units efficiently.

This ammunition is suitable for law enforcement training, tactical rifle qualification, precision shooting at intermediate ranges, and civilian marksmanship practice. The 300 Blackout 125gr FMJ is compatible with any standard 300 Blackout rifle platform and functions across a wide range of barrel lengths and suppressor configurations. Frontier Cartridge maintains consistent quality control across its product line, making this loading a dependable choice for shooters who require ammunition that performs predictably downrange and feeds reliably through their platform of choice.
