I acquired a stock and forearm for my 1947 stealth sweet sixteen and it didn’t fit right. It was allowing the barrel to sit to far forward causing the diver part of the barrel extension to be seen. Also the charging handle was contacting the front of the ejection port. I tried a few different forearms and determined that the issue was with the used forearm. I was going to shim it originally but after trying to get shim stock cut to the right size I gave up. I decided to use epoxy similar to bedding a rifle. I removed the forearm, barrel, and recoil spring. I gave the magazine tube and barrel a liberal coating of Hornsby One Shot case lube. Then I duct taped the barrel and receiver together with what I though was the right amount of barrel extension protruding. Taped the exterior of the forearm and the barrel channel. I used Loctite epoxy and carefully put it where the barrel ring sits. Then I slid the forearm on and installed the magazine cap. I cleaned up the excess that squeezed out with a-tips and rubbing alcohol. I let it set up for a few hours and broke it loose. I thought I nailed it but I had to remove a little material. I filed the flat part and borrowed an 1-1/4” annular cutter from my work’s machine shop to remove the rest. Not the prettiest but I think it will work well. We will see if it holds up to the abuse.
