    Default Question for you VZ58 owners/builders

    I'm 3 rivets, some sanding, 3 compliance parts, and a paint job away from completion!

    I can't seem to figure out if the sear spring is riveted in place, or does the hole sit "around" the rivet so you can take it out for cleaning? In all the pics I have, I can't tell if the factory assembly is riveted in place.

    When I test fit the original FCG parts, I'm using a rivet to keep the spring in place, but the rivet isn't squashed yet - it just sits there. That was the only way I could test fit it and keep all the parts in place when I cycle the action. So the spring is sitting on top of the rivet head, about 1/16" higher than the bottom of the receiver.

    I think this is causing the spring to push the disconnector too high. So when I cycle the action, the sear locks against the bolt carrier such that the "back" of the sear, not the ridge, is catching the carrier. Thus, when I pull the trigger about halfway back, the carrier slides into place, then when I pull it back the rest of the way, it is THEN that the sear releases the striker. Is this normal? Or should the sear be catching only on the hump?

    I'm almost positive this is due to the rivet head pushing the spring at an odd angle, but I figure I'll check first before I smash the rivet.


    Oh, a second question - does the VZ carrier "hang" halfway back, like an AK carrier that hangs against the trigger "hump"? Or does the VZ carrier glide easily?

    HC,
    The rivet goes through the TG plate and the sear spring. The carier should slide easily. Which compliance parts are you using? If you are using PBB's, The sear slot in the trigger needs to be fitted for sear engagement.

    the bolt will hang a litle on the disconnector going both ways.

    The spring needs to sit flat against the bottom of the receiver. The rivet normaly hods the spring in place but it doesnt need to be under the rivet. I actualy use an 8-32 allen screw comming up thru the botom of the receiver and a small nut to hold it in place. The nut is only needed if the safety is out so the spring wont get lost.
    The one I have been shooting the past year has had the spring sitting over a screw with nothing but the safety keeping it from moving around.

    When testing the fire control group make sure the safety is in place, its crucial as it gets the sear and disconector in the proper relationship to one another.

    The big spring shouldnt have any effect on the hieght of the disconect, the safety is what limits its upward motion, the big spring just keeps the sear up and the safetty from rotating. Hope some of this rambling helps

    Thanks guys, that definitely helps out! I wondered if the disconnector bump was the 'hanging' problem - thanks for confirming PBB!

    The few pics I have show the spring in place with a *very* nice rivet head. My problem is that the rivet I just inserted into position has too big a head for the spring hole, and pushes the spring up and away from the receiver. That obviously affects the catch for the top cover and the safety. I guess I need to lathe that rivet head even smaller! (I'm using a home-made rivet from a 5/32 rivet lathed down to .220" head).

    Speaking of rivets, what really sucks is since I put a HUGE weld bead inside to keep the sear block in place (trying to make it obvious that it was added to the receiver if anyone inspects it), the front rivet must be hammered into a blind hole like with a 1919 rivet. Not really an "oops" problem, but unexpected.

    rbthntr64, I just bought a huge block of 4340 steel from aircraft spruce and I'm using that to machine compliance parts.

    That begs a question - how many parts are needed? I'm counting six, because I'm counting the wedge shape as the disconnector, and the thin humped piece on the trigger as the sear - I'm basing that description on the function compared to my other rifles. Also, I'm counting the striker as the "hammer" due to its function.

    Therefore, with the muzzle extension, I'm counting 16 parts total for this milled beauty, of which I have 6 shop-built parts: receiver; muzzle attachment; piston; sear; disconnector; hammer:

    barrel
    receiver
    muzzle attachment
    piston
    bolt
    carrier
    hammer (striker)
    disconnector
    sear
    trigger
    handguard
    buttstock
    pistol grip
    mag body
    mag follower
    mag floorplate

    the sear is the wedge piece that catches the striker, the disconnector is the piece with the hump thats pinned to the trigger.

    6 is also what I came up with on my count
    I use the following US made parts
    Receiver
    Trigger
    Sear
    disconnector
    Gas piston
    muzzle attachment

    the disconnector isnt in the pic but it looks just like the original


    as they are the easiest for me to make.The grip is pretty easy and avail from a couple of sources
    I submitted an entire vz58 last week and was told it along with my receiver submission from last year would be sped thru and I should have an answer on both within 30 days

    On a side note it was conveyed to me that if a repair section like mine or prexis was used by welding it to to the original rec stub that they would consider the original portion of rec still attached to the bbl as a trunion which would increase the imported parts count by 1 to a total of 17. I would assume this would apply to any milled ak build in which the original front portion of the receiver was used and plates or repair section were grafted in place.

    COOL! That will be most excellent to finally get the results! They've taken way too long with yours

    Good to know. I'd like to see it in writing before they start identifying "parts" of the receiver as the receiver, but I can see how they can justify a Czech receiver stub as a part that is different from a receiver "shell".

    If so, then floorplates won't be difficult to make... time consuming, perhaps, but not difficult.


    Thanks for the info!

    Jestism/Prexis has nice wood stock sets for easy compliance parts. I don't really care for the bakelite or whatever they call that crude chipboard looking material.

    just fyi there are 17 parts that count as the handguard and fore-end are seperate pieces and both work against you

    Nothing like reviving an old thread!

    Do you know this for certain, or are you guessing? The reason I ask is that it has already been established that the upper and lower handguards are counted TOGETHER as one piece. "The handguard and fore-end" are therefore one piece. The parts count tallied before is accurate. Unless you have some documentation that states differently?
