Product Description

Omaha Outdoors has the revolutionary new PWS UXR 300 BLK rifle that allows the shooter to quickly convert between alternate calibers for sale. This new design from Primary Weapons Systems will enable you to change calibers on your serialized platform by changing the magwell, barrel, and bolt head. The long stroke piston operating system has been retained and modified specifically for this rifle system. It is equipped with the barrel Xchange system and allows the user to quickly change out between 300 BLK, 308 WIN, and .223 Wylde, with more calibers to be added. The 14.5 inch barrel features the new bore evacuator, which directs gases away from the shooter and down the barrel. Other features of the PWS UXR 300 Blackout are an ambidextrous folding buttstock with adjustments for length of pull and cheek weld that’s attached to a 1913 Picatinny rail section mounted on the trigger housing and a 3-position adjustable gas system with a dedicated suppressor setting. Omaha Outdoors has the PWS UXR 300 BLK for sale, but please check our website for current availability.
