After balking for years I have finally decided to build my first ar pistol !
One thing however that seems to be a matter of some disagreement is the size of the GAS PORT HOLE in the barrel. My plan is for a 7.5'' barrel of
"hbar" profile,,,, and let me say I turn , port and proflie my own barrels . For this build I am planning on useing a kreiger match ss 1 in 7.7 .
I have talked with many ar pistol shooters and shot many but none have too much of an idea of the current consensus as to the size of the hole .
Various pistol barrel producers use slightly diffrent size holes I am told and there seems to be an argument as to the port hole size vs. functionality
as well as the relationship between the hole size as it relates to 7.5'' barrels and up to the longer pistol barrels . ALL the many other barrels I have
"made" have had ZERO reliabilty issues as I have tried to do as much research as practical for the length of barrel , gas port location etc. some
have had nonstandard port size as well ..........any help in this area from some of you out there that are in the know or just have an opinion will
be greatly appreciated .............................................................................................IRONSIGHTRANGER
