The Firearm Blog abuses the favourite AR in airsoft, the MK18, but this one's the real deal... "In this episode of TFBTV, James Reeves asks “is the Mk18 reliable?” For the unaware, the Mk18 is, more or less, a 10.3″ barrel short and compact AR-15 or M4 that is common in the special operations community. There have been criticisms of the platform over the years and calls for its replacement – but does it really need replacing? To answer the question, James reviews military and government reports about experiments on the Mk18 and discusses them. Additionally, and just for fun, the TFBTV crew and Pensacola Police Department SWAT throw together an informal torture test to see how tough the Daniel Defense DanielDefense and Colt full-auto M4 lower combo – similar to what would be issued to the special forces operators who use this setup – really is."
