stylebender09Like new (less than 40 rounds fired) MR556a4 upper receiver kit. Includes everything that it came with from factory, buffer/spring, complete bcg, charging handle, aswell as an HK a4 pistol grip and ambidextrous safety levers. I am the original owner. Purchased new a few months ago from Blue Ridge. Never left my home. Shot about one full mag off my back porch. Not selling because I don’t like it, selling because I love it and will be purchasing the complete sbr. Price is shipped. 🙏 Getting alot of trade offers.. only a few specific things Im needing.. would trade this for a complete 16” or 14.5” mr556a1 in good shape + a little cash on my end. A new or like new 16.5” mr556a4 upper. Other HK parts maybe, or high end optics but would need to be in my favor $ wise.
