Dick's Sporting Goods has decided to destroy its stock of AR-15 rifles. If you'd like to do the same, I suggest you refer the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)'s official guide to destroying "machine guns" that would surely be effective to render AR-15 rifles completely useless. The key tool is "a cutting torch having a tip of sufficient size to displace at least ¼ inch of material at each location."
• Each cut must completely sever the receiver in the area indicated by the diagonal lines.
• The receiver must be completely severed in each area indicated with a diagonal torch cut.
• Cutting by means of a band saw or cut-off wheel does not ensure destruction.
