I have a DPMS 24" heavy/fluted 1/9" black teflon coated barrel on an A3 Upper. Less than 500 rounds through it, great varmint gun. Includes aluminum free-float tube w/ sling stud for bipod. Upper is in great condition and shoots 1/4 MOA with BH 68 gr Match. Sorry no pics, will give a 3 day inspection period as insurance. No B/BC/CH.
