Winchester 1200 / 1300 20 Gauge Lower Magazine Throat

Replacement for missing part. Seems to fix my problem.

It fits my Win 1200 in 20 gauge. I bought the upper piece as well, though only the lower was broken. I hope I can remember how to do this next time it breaks; judging from the info on the forums it is a fairly common issue. Bang the mag tube back into the receiver to remove the old mag throats. Take care not to mix them up, the bigger piece is the lower part, closer to your hand if you are aiming the gun. Clean and lube the mag tube end, just the part that came out of the receiver - in hopes that it will go back in easier, but it probably won't! The grooves in the plastic throats correspond with the grooves in the mag tube. Match them up carefully. Now the fun part.... banging them back in place. I ended up using about 12" of a broom handle, laying it down in the cup-shape of the throat. As in 90 degrees/perpendicular with the gun. Bang on that with a hammer. The curve of the broom handle is close to the curve of the mag throat, so the force is distributed. Probably professionals have a real tool that makes this easier. But it took a lot of (careful) banging to get that plastic all the way down. And you do have to get it totally seated or the retainer clip will get hung up on the plastic throat and not allow your shells to feed from the mag to the chamber. That took a couple hours to figure out and fix. In all, probably a four hour job that I hope to never do again, but I learned a lot and saved some $ in the process. So, it's a win! The part was perfect.
