Scooter,
I received your personal request for a source for 03 parts, but couldn't get the reply to go through this system.
So I'll answer here.
I believe the best person in the business for these parts is William J. Ricca. (billaricca.com).
He is a one man operation, so have some patience.
For quality, honesty, and anything else that matters, I cannot rate him higher.
First of all, make sure that this part is what you need.
If you are uncertain, take the rifle to someone qualified to diagnose the problem.
If you can, borrow the striker assembly from another 03 and try that.
Good luck.
