T1x Ultimate Precision Rifle introduces a new kind of lightweight stock construction: the bedding features an extra layer of carbon fiber mixed with fiberglass for increased rigidity and accuracy. The stock is coated with a rough surface for the best grip in any condition and has attachments for QD slings. T1x UPR rifles are all muzzle threaded with either 1/2 "-20 UNF or 1/2 "-28 UNEF thread.
