A semi-automatic civilian version of course (nobody will sell you a military unit if you don't have a special permission). But... you don't need to print anything. If you buy a Kalashnikov riffle made in Russia (not in China or Bulgaria) you can be 100% sure it won't take out your arm or your eye. I do believe the situation in the USA is similar. Just buy the officially made AR-15 and don't worry about your arms and eyes.
