It's a 12.5 inch Hodge defense barrel in 5.56 with a 1 in 7 twist. I ordered it from Big tex ordinance. ($450) with a 10in Centurion quad rail ($265) , spikes upper ($120), Spikes Tactical bcg ($135). Charging handle Radian Raptor ($75). The lower is a Spikes Tactical (punisher) with a BCM lpk and magpul furniture. ($300). Sig optic combo ($270). Surefire scout ($300) and pad($110). Has been rattled by me and feels great. 
Has a rugged suppressor mount on it but can swap out muzzle for a few other options if wanted.

 

thanks and God Bless
