I am working on my 2nd AR build and my first Grendel build. I purchased my barrel from AR Buildbox from this forum.
During the transaction he asked if I was installing adjustable gas, I was thinking about it (at the block) and he recommended the Rubber City gas key or bolt carrier w/gas key.
I already have a bolt carrier that was dog eared for the project, but didn't want to change out the gas key because I didn't want to go through the process of staking the new key in place.
So how critical is being able to adjust the gas? I'd think wide open the rifle should cycle fine. And with a rifle length buffer/tube/spring that it shouldn't be overly gassed?
What am I missing?
