Frontier Tactical announced the company was now offering a new AR-style rifle called the FT-15 War Lock Entry Carbine. This rifle uses the company’s War Lock multi-caliber system that allows for multiple barrels with a single upper receiver.

The standard carbine comes chambered in 5.56 NATO with a 16″ 1:8 barrel that is equipped with an A2 muzzle device. However, the front of the receiver has the War Lock device installed. Additionally, the ejection port is enlarged to handle larger calibers like the .458 SOCOM and .50 Beowulf.

The War Lock device replaces the standard barrel nut and allows for a new barrel (with hand guard) to be swapped out in seconds. Calibers requiring a new bolt can swap that out in the normal way. The below video shows a War Lock equipped gun being fired on the range. The shooter demonstrates several cartridge conversions including the 5.56 NATO, .300 BLK, 6.8 SPC and .458 SOCOM.

The guns are made in the United States and start with forged 7075-T6 aluminum receivers. Frontier Tactical uses a mil spec Type III hard coat finish. On the base gun, the company uses Magpul MOE furniture with a low profile gas block. Even though the War Lock system is significantly different than the typical AR, all other parts are mil spec compatible. In other words, it would be easy for you to trick yours out.

The suggested retail price of this gun is $1,200.
