I have a Topper I use as a Barn and Beater gun.
Because it is left out in the elements, I decided to replace the hardwood stock and forend with a Choate plastic stock and forend.
The forend went on without issue.
When I went to remove the buttstock, It was very difficult to get the bolt to turn.
Once it did, all it took was two and a half turns and the buttstock came right off, hmmm.
Once it was off, I couldn't get the stock bolt out of the stock and I needed it for the Choate stock.
After fiddling around with it for a bit, I finally got it out, took a look and WOW!
The factory stock bolt was bent!
Worse yet, whatever genius had force installed the stock at the factory botched the threads on both the bolt and the hole on the rear of the receiver.
The through hole in the buttstock was misdrilled so the bolt didn't quite line up correctly with the hole in the receiver. Instead of getting another stock, the factory assembler just forced the bolt down into the hole until it tightened the stock to the receiver cobbling the screw and the receiver threads, but hey, the stock was tight, good to go right? Wrong!.
Take a look,
I went ahead and ordered a new bolt from a factory repair center with a one week delivery but decided I could do better than the factory bolt.
My solution came from Fastenal in the form of a hardened stainless steel bolt and lock washer.
I also chased the threads in the receiver with a taper tap to clean them up.
The new stock assembled without issue.
If you ever need to replace one of these screws, they are 3/8"X24NFX4" long
Don't order a factory bolt which will set you back $6.00 plus shipping.
The Fastenal Stainless steel bolt complete with a new lock washer came to $4.00 including tax.HTH
