For all of the recent purchasers of the Century VZ2008 with the extras and of course all other owners of VZ58 type rifles. I discovered how to use the cleaning tools included with the rifle to reinstall the recoil spring, guide and retainer. Hopefully this information will help others not to launch their retainers into unknown areas, never to be seen again. After launching my retainer, I looked online for more info into how to reinstall the spring, guide and retainer. I found several very good ideas right here on this forum. I started to think of how the spring, guide and retainer would be installed if I was a member of the Czech military. I checked out the cleaning tools and spotted slots on each side of the slotted cleaning patch holder, that are the right size to hold the guide wire. Now put the two pieces of the cleaning rod together and install the patch holder. Place the guide on the other guide attached to the top cover, place the open ends of the guide wire on the patch holder. Now slide the recoil spring over the cleaning rod with the guide wire attached. With the extra length and weight of the cleaning rod attached, you can compress the spring fairly easily, making sure the guide wire is at its max length. After the spring is compressed enough to remove the cleaning rod from the guide wire, you can now install the retainer and slowly release the spring and it will be held by the retainer. A lot more words are needed here than to do this procedure. It took me about 5 minutes to accomplish, of course, after the replacement retainer arrived in the mail. Sorry no pictures. Any questions? I hope this helps!
