I have a lightly used SU 16-C for sale (less than 500 rounds). It comes with quadrail, folding stock, bi-pod forend, and two muzzle breaks/flash hiders. I also have PMAG's and about 750 rounds of assorted ammunition for sale. PMAG's are 20$ each (I have 8 brand new). Will sell all 750 rounds for 300$. Handy little AR hybrid, im only getting rid of it because I am moving.
