The SCOUT V2 is very similar in design to the APEX centerfire rifle but without the interchangeable barrel capability. So for the hunter who wants a high quality single shot rifle in only one caliber the SCOUT V2 is the ideal choice. Sleek lightweight and easy to operate the SCOUT V2 sets a new standard for affordable single shot hunting rifles. The SCOUT Pistol continues with the SCOUT rifle's accuracy and sets a new standard for accuracy in handgun hunting. Pistol barrels are non-interchangeable. - CALIBER 350 LEGEND - BARREL 14" Stainless Fluted, DuraSight(R) Z2 Scope Rail - GRIPS Black Polymer
