Well, I assembled the upper for my new .308, including checking the
headspace with a borrowed "go/no go" kit and pinning the gas tube/block

for him to check over my work. Compared to the "bare, naked" lower,
assembling an upper is pretty easy. If the weather sucks this
weekend, I'll start on the lower.

Someone probably believes you, Krause. Wonder who?
