I bump fired my mini and it was throwing brass about 60 feet laterally and 15 feet in the air. You could get an adjustable gas block, or even a new bushing with a smaller hole to replace the standard one. If you do take off the gas block, it's probably a good idea to get an inch pound torque wrench and make sure the bolts are evenly torqued to spec.The only thing I dont like about the gun is when my brass gets tossed across town and I cant find it.
