Crusty, per Bill Alexander, the gas ports on my F18 mid-lengths are 0.076".
ALS, gas port on the F20 rifle-lengths is 0.093", so "should" be OK. Let's keep an eye on it as it breaks in. This is a complicated thing because it also depends on ammo variables, buffer weights, build quality and parts fit, lube regimen, etc.
