LTC Joel Johnston, US Army Ordnance (Retired) test fires the Century Arms AK-74 to determine if there is still a key holing issue with the 1-8 inch twist barrel as was reported by many customers when Century first started selling the rifles in 2008. The original barrels were 1-7 and 1-10 inch twist and the key holing was reported once the barrels heated up from firing 3 magazines of ammunition. Filmed on location at the Cooksey Ranch, Texas.
