This is an earlier model HK MR556. Comes with Geissele 14.5" rail and charging handle. As well as the original soft carry case, all paperwork. Factory rail, charging handle and flip up sights. This gun is absolutely amazing and definitely lives up to its reputation. Will NOT come with the Vortex Razor. Will sale for 3800.00. Only trade interested in would be a KAC 11.5" with either BCG and cash on your end. I am willing to travel for the deal to make it make it work for both parties. I will only respond to text. 9o3-658-1168. Located in Tyler.
