AAC was pimping a prototype that looks awesome.
What's the cost on all this?
The only other one I'd look at is a X-Ring 10/22® .22LR SB-X Barrel. This shortens the barrel to 12.5 in but has a "shroud" that keeps it to 16.5 in.
The barrel from Tac Sol costs around $350 plus your silencer cost (Silencer + Tax + Trust + Fees).
