Need assistance - question about CAR-type AR-15 barrel
 

Have a barrel question...

I have one particular AR-15 that needs a new barrel (no-go guage failure). Bought the thing at a gun show several years ago. Lower is a "pre-ban" era Eagle Arms. The flat-top upper has no markings on it. Checked with Armalite, when Eagle Arms sold the lower in 1996, it went out only as a lower. The barrel on this gun is unique (at least to me), and is of a type that I have not seen before, other than on this gun. The barrel is stamped "A MP 5.56 NATO 1/9"... nothing unusual there. It has a flared CAR-style flash hider. On most CAR-style barrels, you have an 11.5 in. barrel, with a 5 in. flash hider. On this particular weapon (here is the unusual part), there is 16 inches of rifling- the barrel runs all the way up through the CAR-Style flash hider.

Does anyone know who manufactured this type of barrel, or if it is still commercially available?

Pictures of it are attached.



Thanks for your assistance.

You have an original Armalite copy of a Colt XM-177. The barrel is 16" and the flash hider has a "tube" that goes down back over the barrel to give it the look.
