How difficult and what is involved with putting an oversize bolt knob (i.e. Badger) on a FN PBR XP? Thanks in advance for the info. and help.

Dip the ball into a can of Plastidip. Let dry. Dip again. Let dry. Repeat as necessary to get an oversized ball. It is a lot cheaper and less permanent than having something change the bolt handle.

I get my Plastidip at Home Depot. My local harbor freight also carries the stuff.

No more so than any other bolt gun.
1) Cut off the old knob.
2) Weld on the new.
3) Dress weld with files and sanding drum.
4) Refinish.

Alternate steps
2) Chuck bolt in lathe fixture. Turn and thread end of stub.
3) Screw on new bolt knob.
4) Refinish as/if needed.

As BBBBill said they are the two methods for a permanent new knob. I would recommend TIG welding if you are going to go the welding route as it puts less heat into the metal and minimises the steps needed to prevent drawing the temper of the bolt body! The second method also has the advantage that you can change the knob with a different style as and when you want.
