I recently bought 1100 rounds of IMI .223... before I read the extensive thread on others' RGuns experience. The order was filled promptly. I fired the fist rounds yeaterday and, though 40 randomly selected rounds is a small statistical sample, they functioned 100%. I will definitely inspect every round before using these, but based on my limited experience thusfar, I have no complaints. Maybe RGuns is working to address their problems.
