The 16 in barrel is made from 4140 alloy steel and is cold hammer-forged and chrome-plated for durability and easy maintenance. It uses a 1:8 RH twist to stabilize a wide range of .300 AAC Blackout projectiles. The muzzle is threaded 5/8x24.
This rifle runs a semi-automatic, direct impingement system with a pinned low-profile stainless .750 in gas block. The setup is built for reliable function with .300 BLK while keeping weight balanced and handling crisp.
The FN Wedge Lock free-float aluminum handguard features an M-LOK interface and a 13.625 in length, with M-LOK slots on the sides and bottom, and a slick 12 o'clock with short Picatinny rail sections at the receiver end and near the front (non-continuous top rail). This design provides rigid accessory mounting while keeping the barrel free-floated.
The receiver includes a forward assist, ejection-port cover, and brass deflector. The upper is marked "300 BLACKOUT," and the receiver is rollmarked "FNH USA LLC, Fredericksburg, VA." It accepts standard AR-15 pattern magazines, with capacity noted at 30+1.
Furniture includes a 6-position collapsible stock and a Magpul MOE pistol grip. Factory specs list an overall length of 34.0–37.25 in and an approximate weight of 7.23 lb. A manual safety is standard.
