The FT-15 is offered in two configurations, both of which come with 7075-T6 forged receivers and offer an enlarged ejection port, allowing cycling of the largest caliber cartridges available for the AR-15 platform. The FT-15 Entry Carbine was designed for the AR-15 shooter. The lower receiver is marked "MULTI CAL" and is a semi-auto AR-15. Once installed, the AR-15 is modularly capable of firing over 90 calibers by changing simple components.
