Mossberg 590 Front Sight Replacement

[Bowie]

So my buddy's 590 front sight (ghost ring) went AWOL from the dovetail in its base. Does anyone here know of a place to source a replacement - either oem or aftermarket? Any suggestions?
Thanks

Quick email to mossberg will likely get one in the mail for free.....

XS sights. Might as well replace the cheap POS on the rear too
