The newest version of the Ruger PC Carbine, the Model 19115, retains all the features of the original, such as the ability to accept either Ruger or Glock magazines, the dead blow action with a custom tungsten weight, and its quick and easy takedown. But Ruger modernized the gun with an aluminum free-float hand guard with plenty of M-LOK slots. The 16.12" barrel is threaded and fluted and is eccentric in the fore-end to get the sights in the proper place. Sights are an adjustable ghost ring in the back, and a blade front protected by ears. As American Rifleman's Brian Sheetz proclaims in this "First Look" video, "Now that's just a lot of fun." For more, visit Ruger.com.
