HK MR 556 A4 Complete 11″ Upper Kit BRAND NEW

Description

I have a brand new HK MR 556 A4 11″ Upper kit. It comes with everything it did from the factory: the upper, HK bag, BCG, Buffer and Spring. It has never been mounted to a lower or used in anyway. I got it thinking I would build out a nice lower for it, but some things came up and that’s no longer an option. Not interested in trades.
