The 2T came with dual sling mounts on the FSB lower, and to the left side clamped to barrel at the FSB.
It has a Sampson Star-C, free float, quad rail. The quad rail features a removable lower section, via a push pin release, to accommodate such add ons like M203, shotgun attachment, etc. The rail is very sturdy, hast T-markings, and rearward QD sling swivel points on the left and right side, as well as one forward on the bottom. Black rail ladders (3) are also provided.
The FSB is F-marked and has a bayonet lug.
The Barrel is chrome lined as well as the chamber, and comes in the 16" M4 configuration. It has standard feed ramps, which appear more than adequate, as viewed with a mag in, come all the way down to the front edge of the mag level. M4 feed ramps would appear to have been well below the top edge of the mag.
The included rear BUIS is an A.R.M.S. #40 L.
The rear sight is metal, .75 MOA, and is very stout. Dual apertures both feature a slot on top that is ideal for CQB fast aquisition and target ranging.
The 2T comes with a standard A2 grip and a 6 position mil-spec buffer tube assy, and collapsible stock that is very adequate.
The 2T is very light as is, and I'm very happy with it.
I paid $950 out the door which is an excellent deal.
