I have two 5.56 rifles with 24” barrels. They have rifle length gas systems and have functioned just fine and don’t damage brass, at least as far as I can tell.
I want to order 2 more complete uppers in 5.56 with 400 MODBB and I noticed that there is an option to have a +2” gas system with the 24” barrel. Will adding that extra two inches of gas port distance change anything WRT reliability or expected velocity?
I’m tracking the reason AR10’s in 6.5&22 CM have the + gas system. But I’ve never seen it on a 5.56.
Not planning on suppressing the uppers when I get them.
Thank you for your time.
