Selling a barrel with no more than 500 rounds through. Started as a midlength FSP combat grade barrel. I shaved down the the FSP and installed and Midwest Industries 15” combat handguard. Corner was rough, had to file down to fit upper but the friction fit is tight on the barrel nut. A little spray paint left on the A2 flash hider. Add a gas tube and torque to your upper. Comes with barrel nut wrench. $225 shipped.
