Sure K guns are good, but the manufacturer knocks out a lot of them every year. As any mass produced item, the blame lays with the person doing the final inspection. A Chevy & Caddy both have the same life expectancy, engine wise. A K gun being designed for competitive sports should have a much longer life than any field gun. However, being a mass produced item, there are slip ups, who knows maybe the bad guns were made after Mon. night football or the equivalent. If you get a Bowen, Seitz, & an Infinity. You're getting a truly custom gun with a person who can stand behind their product.
