I have a brand new 14.5 EAG Tactical upper, it is the one with the larue rail. It's is complete how it would come from the factory the A2 is not permanently installed so you can put any device you want on it. It has sat in the closet ever since getting it. I would like to trade for a 12.5 upper preferably new as well and complete. Anything 10.5 to 12.5 would be considered. If interested I will send pictures.
