if you need a barrel threaded - get ahold of adco.
theyve done 4 barrels for me so far and do nice work & turn around is quick.
send them the barrel only, and its $65 for thread pattern of your choice + shipping both ways of course.
they will also turn thread protectors for an additional $15 to match the barrel profile for you while its there.
[edit] just a happy customer. no other relation to adco.
and i hear ya on the noise from a 16" 308 upper. I've got a LR308 that in its original incarnation is a 16". I built a 20" upper for it last summer.
