The Predator XT is built on an AR-15 direct-impingement platform with aluminum receivers and a billet-style lower that incorporates geometric/lightening cuts and an integral oversized trigger guard. The upper includes a forward assist, shell deflector, and an ejection-port dust cover, with T-marked top rail segments. Receiver markings include "PREDATOR XT," "SPF, LLC KYLE, TX," and "CALIBER MULTI," while this example is chambered in .224 Valkyrie.
Its 20-inch stainless heavy-profile barrel is threaded and fitted with a three-chamber side-ported muzzle brake. The free-float Diamondhead USA aluminum handguard carries a full-length top Picatinny rail that aligns with the upper for a long, continuous 12 o'clock rail across the receiver and handguard.
The Luth-AR adjustable precision stock is mounted on a carbine receiver extension and offers a length of pull adjustable from 12 to 14.5 inches, along with cheek riser and buttplate adjustments. The stock is tan, glass-filled nylon, and the rifle is finished with a tan ERGO pistol grip for a consistent, ergonomic hold.
Controls include an ambidextrous safety selector. The rifle uses a detachable AR-15 pattern magazine interface, and this example has a capacity of 15+1. A detachable bipod with a QD-style clamp is installed for added stability at the bench or in the field.
Made in the United States, the build emphasizes rigidity and modularity with its aluminum receivers and free-float handguard. The stainless heavy barrel and installed brake complement the .224 Valkyrie chambering for precise, repeatable performance.
