I have a midlength 16 inch, MP tested, 1/7 twist, chrome lined, M4 cuts barrel for sale. It comes with the barrel, front sight base, front sight, delta ring, barrel nut, and gas tube. Its made by ER Shaw and has had zero issues. Less than 100 rounds through it. The barrel is heavy under the handguards and balances great. It is attached to an A3 CMT upper. It has a keyhole forge marking. It does not have M4 cuts. It is complete with port door and forward assist.
I am looking for $325. Paypall accepted.
