Hi guys thanks for having me on the forum! Forgive me if this topic has been gone over too many times...
For about a year I've been sitting on a Grendel build I have planned and I am finally finding time to port and chamber the barrel...I am using a Bartlein 5R 1/7.75 blank that is profiled for a rifle length gas. Using a Grendel reamer with the same neck as a .264lbc... My plan was to finish it at 20" with an adjustable gas block and I was wondering what gas port size I should use at 20".
I will also be shooting suppressed most of the time so I was starting to hope I can go go down to 18", but can I get reliable function out of a rifle length that short? Someone was telling me to use .102 gas port, but that seems pretty large.
