Where do you order a trigger guard for a Wards Western Field 22 bolt action rifle No. 470 22 L-LR?

Cannot find an exact match- but if your trigger guard is black plastic- and especially if it has finger grooves in the tail of the guard- it was probably made by Mossberg. You can order replacement trigger guards from havlinsales.com There are 3 different trigger guards- check the photos to see if they match your rifle.
