RRA is the only place i've been able to locat a 16" CL w/mid length guards.  i understand their CAR is not an M4 Gov profile, what i don't know is whether or not it would be considered an HBAR?  the person i spoke with on the phone could not advise outside diameter on the barrel.  i figured one of y'all would know.

thanx.

oh yeah, would a standard bayonet fit properly on a 16" w/midlenghts?  it looks like it would.

If you get it from RRA then it will be HBAR.  Adco sells RRA barrels that they turn down to a lighter profile and refinish.  I bought a 16" chrome lined midlenght from them last summer and have been very happy with it.

I have a16in car and it's hbr .750 at muzzle.Very accurate for a shorty like it so much got a 16in mid-lenght on order from rra 2 month wait .
