I need the correct Gas Port Diameters for various barrel lenghts example; 20in barrel rifle length gas system = .000in dia gas port 18in barrel rifle length gas system = .000in dia gas port 14.5in barrel carbine length gas system = .000in dia gas port 10.5in barrel carbine length gas system = .000in dia gas port I know this information has been posted in the past I just can not seem to find it and yes I tried the search. Currently my time on the internet is very limited and so I am asking for a helping hand. Thanks in advance for your reply |

I did could not find the information on the Maryland site. What I really need to know is when working with barrels of .750 diameter at the port. How big of a hole must be drilled when going from a 14.5in to 10.5 inches barrel and starting with a standard 20in rifle barrel the diameter to drill the gas port after cutting the barrel to 18 inches. Any help would be greatly appreciated Thanks again |
