Q&A for Hogue Winchester 1300 Overmolded Shotgun Stock Kit with forend OD Green 03212 — 6 Questions & 6 Answers

Yes it will fit

The Hogue Winchester 1300 Overmolded Shotgun Stock Kit does not include the action slide tube.

Sling doesn't attach to forend, it attaches to the magazine tube cap (which isn't included). Most factory caps don't have the swivel stud, so you'll probably need to buy a new/used cap. This is the part number for the only one I've found on here - GTSW294. Otherwise, ebay has factory sling caps for the 1300.

All you need to do is measure your Action Bar on your Winchester 1300. If it is 4 3/4", you will need the Hogue forend adapter kit (Item # 03320). If your Action Bar measures 6 1/4", this forend will fit without the use of an adapter.

Yes, this is designed for the 6-1/4" action bar. They also have an adapter that will let it work on the shorter 4-3/4" action bar that can be ordered separately: https://www.opticsplanet.com/hogue-forend-adapter-nut-for-winchester-4-75-forend-tubes-03320.html
