My VZ-52 that had a sticky chamber has been fixed, I am happy to report! My first shot out of the gun sent a bullet downrange on target, but the case was stuck, seemed to be for good. I got home, tapped it out from the inside with a rod, and set about trying to find out what went wrong. You folks set me striaght- thanks!
I cleaned the chamber with a chamber brush, then polished it up with a 410 guage shotgun swab and some flitz metal polish. I chucked the end section of a cheap Hoppe's aluminum cleaning rod in my drill and used the shotgun swab at medium speed. Once the flitz had done its job (several applications), I cleaned it out really well. I then coated the chamber with a thin film of Tetra grease (synthetic with teflon) then wiped it out with a clean shotgun swab to leave behind just the most microscopic film. I also cleaned all my ammo with a rag lightly dampened with CLP. Result?
No stuck cases!
Now, that done, I determined that my handguard retainer (the thing at the end that slides into the stock's metal endcap that holds the bayonet) is missing some metal. It kept creeping out of its place allowing the handguad to come loose up front Seems the little lug on that sliding retainer has a slight indentation cut into it to grab a crossbolt or some piece in the channel it slides into (follow me?). The rear portion of my lug (closest to the receiver) seems to have been ground off or worn off, so it won't stay locked. I suppose I will have to romve the front sight to get this part off and get a replacement. So I was thinking I could have a welder tack a bead where the lug is and I could dremel it back to shape. Sound OK?
Also, I was going to take the whole thing down to parts so I could bead blast the Gunkote off (the previous owner gunkoted the metal- looks good, but I want milspec parkerizing). I used a trick that I emply with Mosins to depress the sight leaf spring- with the sight leaf up, I put a small piece of hardwood on the spring and c-clamped it down so as to releive the spring pressure. I couldn't get the pin out though (need another set of punches- mine are all peened over and don't fit!) so I let the clamp off. Now my leaf spring is only half as springy. It won't apply pressure to the sight leaf until I set it midway at 500 meters of so. Off to buy parts! But when I get a replacement, how in the heck do I install it so I don't damage it? Any help?
Thanks, sorry so long winded, but I love this gun and will get it back to perfect functioning!!!
