Can anyone point me to a shop that could thread my newly aquired AWB era bushmaster HBAR 20" barrel? And would anyone have a ballpark cost for this type of work? I found some government profile 20" AR barrels for $175 (with the FSB and triangle handguard clips, etc), so if the cost to thread it approaches that, I'll probably just plan to swap the barrel down the road.

Just planning to put flash hider on it, but still figured I should do it right if I'm going to bother.
