This was not their rifle at all, I think you missed the part that this was a used rifle that already a a few thousand rounds through it and had gone in for warranty work twice already... basically a dud to begin with. They already knew the outcome...
Used by other CFET Testers. as a part of the same test, with every failure documented. This is not some random Used Siberian picked up from ####### or the EE and run through testing, it was brand new when CFET got hands on it and started the testing. Same as the WK181 we tested previously.
