10.4 inch PS90 SBR barrel made from a cold hammer forged chrome lined FN brand 16 inch barrel.
Correct length and threads to mate with a P90 flash hider.
The threads on this barrel are not concentric with the bore so it cannot be used for mounting a silencer!
If you don't care about that, this barrel is a great value. The crown is square and without defects, and the bore is in excelent condition.
