***A Federal Firearms License (FFL) is required to purchase this item.***

The FT-15 packages include all the barrels, bolt carrier groups and magazines with the rifle that are necessary to switch between the included calibers.  We’ve included black Magpul MOE furniture, low profile gas block, and mil-spec parts.  Our upper receivers come from the factory with enlarged ejection ports for future use of big bore cartridges (.450 Bushmaster, .458 SOCOM, .50 Beowulf).  Our FT-15 was designed with the capability to quickly retrofit with the War Lock™ Multiple Caliber System.

Our FT-15 comes with the Frontier Tactical™ War Lock™ Multiple Caliber System installed from the factory.  No additional assembly is required.

Every AR-15 is capable of becoming a multiple caliber platform.  For that reason, every AR pistol and rifle we sell comes from the factory with three important multiple caliber upgrades:

  • The lower receiver is marked “MULTI CAL” for all AR-15 cartridges.
  • Our upper receivers come from the factory with enlarged ejection ports for future use of big bore cartridges (.450 Bushmaster, .458 SOCOM, .50 Beowulf).
  • Our lower receivers come with a Wolff Extra Power Hammer Spring installed for harder military primers (e.g., 5.45x39mm, 7.62x39mm, etc).
