The Proof Research PR15 is Proof's carbon fiber barrel for the AR-15, and this one is chambered in .204 Ruger at 20.00". The carbon fiber construction trims weight off the front of the rifle compared with a steel barrel of similar profile, which helps a long, precise AR stay balanced on the bench, off a bipod or carried through a prairie dog town.
A rifle-length gas system gives the long barrel a smooth, soft-shooting gas impulse, and the .750 gas block journal takes a standard-size gas block. Pair it with a free-float handguard and a quality trigger for a light, flat-shooting .204 Ruger varmint rifle built on the AR-15 platform.
