WTT a GSG-5SD for a 16 inch complete AR15 upper receiver. GSG comes with 3 22rnd magazines, red dot scope and tri rail forearm. I also have the OEM box and all that came with the rifle, less the original sd forearm. Prefer FTF in FT Wayne IN.Sling and Insight Technology M3 tacitical light and foward grip not included in the trade offer, but may include if trade is for a quality upper.. I have only about 200 rounds through the GSG and it is a runner. Thanks for looking
