Legacy MCX barrel with matching bolt.

This will allow you to drop it into any MCX upper. Just note that gas setting tabs may not line up perfectly.

Price excludes the Surefire SFA2. If you want that I can include it for 90 extra.

Just over 1k rounds through it. Feed ramps, rifling, and bolt lugs are pristine minus some carbon.

Zero functional issues, just do not use it since converting to 300bo.
