professorshankyColt 10.3" MK18 barrel. This came from Colt as a 10.3" with a factory installed FSB, it is not a cut down M4 barrel. CAGE code and "M P 5.56 NATO 1/7" marked, 06/18 date stamped. Delta ring, barrel nut, and gas tube are all Colt, as are the included M4 handguards. Less than 100 rounds through it (MK18s just aren't my thing), so it's in great shape. The ONLY things I need in trade are a Knights 99166/20214 FF RAS Medium, or a tanodized or "Patents Pending" marked PRI Gasbuster.
SOLD for shipping by USPS Priority with tracking, PayPal G&S only, buyer covers fees.
