If you are driving a vehicle you need to provide your drivers license if pulled over and it's requested. If you are not driving, no physical ID is required.
As long as you are not suspected of committing an infraction or ordinance violation.
Short version: if the police are only talking to you because of your rifle, no you do not have to show ID or tell them anything. (These arguments always seem to pop up in the springtime. gotta love Spring Fever!)
