Re: Supposed "Military" failures
The fact that so many mistakenly believe the footage shown repeatedly in the CNBC piece was a member of the military is not accidental. The entire piece was intentionally conflationary.
The segment showing a guy in BDU's firing a M700 by touching the bolt handle was not a member of the military, it was a local PD SWAT team (Portland, Maine), as mentioned once in the report before they went on to conflate that footage with a statement from USMC sniper school on a problem they were having with their schoolhouse M40s. From my experience in the military, schoolhouse weaponry is usually some of the oldest, worn, and generally beat to hell equipment you are liable to find.
More importantly, the single largest piece of evidence presented by CNBC (the SWAT video), demonstrated a completely different failure.
The only video shown of the safety release/fire failure was of an obviously modified M700 credited to the US Border Patrol.
The US Army, the largest single user of the M700 and Walker trigger declined to comment for the piece.
Bottom line: Investigative journalism is by its very nature sensationalist. Any mechanical device when dirty, worn, or ineptly modified is prone to failure. In the case of firearms, the consequences of failure are high, therefore no responsible shooter should place blind trust in a mechanical device which is prone to failure.
EDIT: More on the failure of the Maine SWAT team's M700s. It is hard to tell from the heavily edited video clip, but it appears that the rifle does not fire when the trigger is pulled, and then fires when the bolt is tapped. My first guess to the cause of this failure is either a very poorly modified trigger, or a very dirty firing pin/firing pin channel. Not the trigger connector. A completely different failure, being trumped up as evidence of a defect in the Walker safety mechanism.
