“I cleaned this barrel and installed it with Mobil 1 Synthetic grease on the extension into an AR-Stoner side charge upper. I shot some 50, 55 and 64gr loads to warm it up and get settled in, then grouped 5 of my 69 SMK/LC Mix brass/CCI small rifle magnum primer/26gr Varget load. This FIVE SHOT group, with a PA 1-8 scope, was 0.6” at 100 yards, perhaps the best 5 shot I’ve ever done.”
