I think the 16" looks good. Enough barrel sticking out of the hand guard for me anyway. I would have kept the Dlask 12.5" if I could have found a thead on faux suppressor, as that barrel did shoot pretty decently.
The rifle weighs 7lbs 8oz with a CTR, Falcon 1.5-5 scope and Burris Extreme Tactical rings. The barrel is a Volquartsen SS carbon tension barrel, which is very lightweight in its self. Gives a great balance feel to the whole package.
