After much drama, Spike’s Tactical has published a massive list of certification documents covering everything from the grease used on the fire control group and the torque wrenches used to the composition of the barrel steel and the testing procedures used on the barrels and bolts.
Astute readers will notice that the many of the dates on the documents are fairly recent, and the certification fuss originally arose prior to that time. Some might then say that the certifications were only acquired after the initial claim regarding testing, materials, etc. However, I was told by Tom Miller of Spike’s Tactical that while he had certification documents dating to 2008 and prior, he wanted to show certifications relating to the actual components used in the LE line of weapons, so random samples of those components were submitted for destructive testing.
Here’s a link to the documents.
