Colt XM177E2

Colt XM177E2

From what I believe this maybe the 2nd or 3rd XM carbine in the series I also believe this is the last carbine before they devloped the more advanced M4 Carbine. The only difference I can tell is the XM177E2 has a shorter barrel than the M4. The XM177E2 can be found in the movies Black Hawk Down, and Heat which is so far the only movies I've seen them in.
