From 12 to 30 shots, clean after each 3 shots. From 31 to 50 shots, clean after each 5 shots. Clean thoroughly with a high quality bore cleaner every 10 shots until 100 shots. This time-consuming process will allow the barrel to smooth out without an accumulation of copper fouling in the pores of the steel. The barrel should thereafter be cleaned every 20 rounds for best match accuracy.
Accuracy continues to improve for several hundred rounds as the rifle breaks in.
ArmaLite recommends Black Hills moly coated .308 Win Match ammunition for both break-in and competition. Contact ArmaLite to order this ammunition. Normal manufacturing tolerances can result in the rear sight being off- center when the rifle is zeroed. To do so, put the rear sight in the center of the rear sight base. Fire a three-shot group.
