I was being a smart azz..... DI has worked that fine for years and years. I"ve got maybe close to 10 new barrels on some of my guns... never ran into a failure, jam etc... which amazes me. Keep em somewhat clean, IE not letting the lube get gummy in the upper, and keep em lubed and they seem to want to run forever.
Which is why I ask... WTF is about gas pistons that folks feel the need?
We had a guy shoot competition highpower one year, he was a high master shooter, took his service gun, shot it ALL year without cleaning the barrel. Wiped the carrier and lubed that every month. He usually shot 12 months of the year. Usually shot 2 matches a weekend if he could find them. Thats typically meaning without any practice and such, and not counting high round count big matches, he was shooting probably on average of give or take, 800 rounds a month, probably closer to 1000 if I wanted to bet.... no issues either.
