Accurate and heavy - Proof Research PR15 Stainless Steel 223 Wylde Rifle Barrel

As long as you know this is not a “tactical” or three-gun barrel, it will amaze with its accuracy. I broke it in with IMI Razorcore 77gr 5.56, what I consider to be good production ammo. After my 30-round break-in, the barrel produced a 10-shot 4” group at 600yds. A 4” group by itself is no big deal. But for production ammo (high SD) and a 10 shot group, this is wonderful. I am excited to start load development for this barrel.
