Match rifle shooters clean/decarbon gas system every time they shoot a match.
The amount of carbon build up will be the same, same pressure build up for repetable
performance. gas plug tightening spec. is 15 ft/lb put a paintmark on the plug/gas cylinder
to line up after future cleanings.The threads on the plug are softer the the cylinder and strech on initial torquing repeted/ torquing or over tightening will ruin them. hope this helps
