Thanks for posting the link, I was trying to figure out just why a military court would be considering such a decision. I agree with this court's findings.

There is a process agencies go through to develop such regulations, some things are beyond an agency's authority and if we want such regulation, it must be voted on and authorized by Congress and signed into law. Bump stocks were never made illegal.
While I personally don't see a need for bump stocks, they are not illegal.
U.S.A. –-(Ammoland.com)-The United States Navy-Marine Corps Court of Criminal Appeals has ruled that bump stocks are not machine guns in the United States v. Ali Alkazahg.
Marine Corp Private Ali Akazahg was convicted of possessing two machine guns, in violation of Articles 83, 107, and 134 of the Uniform Code of Military Justice [UCMJ]. These “machine guns” that Private Akazahg processed were bump stocks. The Private’s defense counsel argued that bump stocks did not meet the federal definition of machine guns. The ruling is found here and embedded below. US Military Courts Rules Bump Stocks Are Not Machine Guns.
