to find the parts list of everything Remington offers for sale go to their website.http://www.remington.com/
then hover your pointer on "support" and click on "parts information" option in the drop down menu.
Under Parts Resources find and click on "Parts Price List"
It will pull up a PDF document that has listed every part that Remington currently offers for all of their firearms including the Versa Max which is at the very end of that PDF.
Why they don't make it simple and list them under "Original Factory Barrels" is beyond me, but they don't!
I have done so much for so long with so little, I am now qualified to do anything with nothing!
