I wanna see a noveske 14.5 barrel and upper with pws adapter or supressor, monolithic upper, afg foregrip, ubr stock, troy back up irons and a eotech to top it off. That would be a very good combo in my opinion.
I run a Noveske 14.5" upper with the Surefire Mini can. It balances and handles very well. The can knocks the bark and flash off the caliber nicely, I was actually surprised how quiet it was compared to an LMT piston upper with 16" barrel.
They are a great platform, kind of a happy median between the 16 and 12.5" rifles.
