I recently got a 1940 era Winchester Model 12 2 3/4 chamber model Full choke 12 gauge shotgun. It is able to be taken apart easily. I will try to make a video or send pics soon. When i have the gun together and it is uncocked it is normal but when i cock it it stopd but the forend keeps going out and the magazine tube keeps going too. i cannot take the gun apart without doing this. this is probably very confusing but i will make a video of me showing it. there might now be a problem at all but i just wanna check
