How about some pics and more detail? What Gen upper is it? Does it have the new bolt or the old one? what's the barrel length? Is the muzzle device permanatly attached or not? Whats the barrel profile? Is the upper Black or MRE? Do you have rail pannels and Irons?
Touche. Not sure one which GEN the upper is, but it does have the one piece carrier. Barrel length is 16.1 with a perm attached AAC flashhider. No rail panels, but the flip up irons are included.
