The magazine is simply a long tube with another tube inside it. The inner tube has a full length compression spring with a yellow or orange plug at the end There is a small tit sticking out at the exposed end. This locks the tube iin place. It's called a tubular feed magazine. The 512x is chambered for .22 shour, long, long rifle, bb caps & cb caps. I've shot at least 10,000 rounds through mine and it's as accurate as the day I got it. I did wear out the firing pin though. I now have to push forward on the bolt to get it to fire.
Correct terminology is 'inner magazine tube assembly.' The BAR22 and BPR22 used the same part, we occasionally have them for around $23.
I assume your are referring to the tube magazine. there is not box magazine. at the tip of the barrel, underneather, you will see a knob. turn the knob and remove the inner magazine tube....................
