For CSA SA Vz.58 owners:
Antoni Zendl Puskar is offering an upgraded dis-connector that they told me should install without modification. The link was posted in the Vz.58 parts sticky about a week ago. Please post results or PM me if you have installed this part. Thank you.
The disconnector may install on other Vz.58 variants
with modifications - see "translated" PDF instructions below.
While the main purpose of this design was for gremlin/hermex they advertise it as also improving overall FCG and trigger function, reducing take up, pull and reset. IMO the VZ58 trigger is a major flaw with the rifle. Personally I have always hated the standard surplus VZ.58 FCG trigger function (the take-up, the long release) and always hoped somebody would design something that would
at least compare with an upgraded AKM trigger (Tapco G2, Dinzag Arms, etc.), so I have high hopes for this design. Zendl makes high quality parts.
I am in the process of ordering a
Zendl disconnector (ZD) for trial within some of the following SA Vz.58 FCG combinations, to see what can be achieved.
The Bonesteel Arms FCG (already in my stock) is also on the list to be tested to compare and perhaps combine with the ZD. I have read some good things about the BS Arms FCG, and on initial inspection the sear is definitely "different" from the original.
If the ZD greatly improves the FCG function then I would probably buy more for other variants, however that reportedly requires modification (filing, cutting). See install instructions below.
Combinations to test:
ZD with original CSA FCG
ZD with Checkpoint USA FCG
ZD with Bonesteel FCG (Modified BStl Sear and trigger)
ZD with CP USA sear and Bonesteel trigger (if that's possible)
The cost of the dis-connector is about $100 with shipping and includes a 2-Year warranty. I would gladly pay double that if it "fixes" the FCG and trigger.
Was kinda hoping someone else has (or will) install it as-well so we could compare notes.
I also including some more Zendl TBRs on the order because I still had more Zendl TMRs in stock, and the shipping is high irregardless of the number of parts, so might as well add a few more to soak up the shipping cost. There might be an extra set (TBR/TMR) available and if anyone is interested let me know by PM and we can discuss price.
Note regarding FX exchange. (Now might be a good time to by parts from eu)
So, if anyone has been watching the FX markets lately you already know that the USD has been on a tear. Yesterday after the FED spoke the USD dropped like a rock but already rebounded by this morning. This is a good this if you want to acquire some accessories and parts (such as this disconnector) from the EU. Your dollar buys more right now, so if your considering parts from Czech companies selling in CZK (Zendl, King, etc...) you might consider the positive exchange rate. VZrifle.com sells in Euros. EUR/USD was 1.06 and you could buy 26 CZK for 1USD at the time of this post.http://www.zendl.cz/index.php/produscts/doplnkysa58/112-modifikovane-tahlo-s-prerusovacem
Modified shutter rod with a circuit for CZ 858 Tactical CZH 2003 Hermex, FSN 01
Modified shutter rod with a circuit designed to help reduce firearm malfunction "Padania dern?ku" (ie. Hermex effect). Defect manifests that after the shot is a new cartridge in the chamber, but the firing mechanism is not tight and not so possible to shoot. On z?palce charge is faintly firing pin. Adherence to this defect have basically all original automatic weapons Sa vz 58 converted to semi-automatic weapons CZ 858 Tactical, CZH Hermex 2003, the 1st FSN It is due to the mechanisms of self-loading, removing components providing a self-shooting mode, thus changing the function of this mechanism. Using a modified shutter rod interrupter is also possible to achieve lower-trigger using the trigger with adjustable trigger overtravel also shorter trigger travel. Before installation, carefully read the installation instructions.

Dear Customer, Thank you for buying our product. After unpacking his book
check the completeness of the box as listed below: Rod shutter interrupter 1pc
Spring shutter 1 pc
Modified pull the switch trigger to eliminate defects in arms "crashing striker" (ie.
Hermex effect). Failure is manifested in that, after firing is a new cartridge in the chamber, but
the firing mechanism is not tight and not so possible to shoot. On z?palce charge is faintly
Firing. Adherence to this defect have basically all original automatic weapons Sa vz
58 converted to semi-automatic weapons CZ 858 Tactical, CZH Hermex 2003, the 1st FSN It
due to the mechanisms of self-loading, removing components to ensure the self
shooting mode and thus changing the function of this mechanism. Using a modified rod
Shutter interrupter is also possible to achieve lower-trigger when using tongue
shutter with adjustable shutter slump also shorter trigger travel. If you are not sure
replacement of the component can handle, entrust this work rather experienced person with appropriate
equipment.
Installation: First, check whether the gun discharged. Then remove the cover from the gun
return springs and the very end. Inside the body of the weapon on the right side in the shooting direction is metal
fuse pins in the shape of T. Push (double-click) on the front of the shoulder with a screwdriver
or a rod to fuse slightly tilted downwards. This is triggered by the capture of striker pins and
shutter which can now be removed from the gun with these components. (U CZ 858 Tactical is
right groove in the trigger-arm spring wire. This spring in use
modified linkage shutter interrupter no longer need to give back to the weapon).
Clamp the trigger for the side surfaces of the trigger in quality with smooth or vice
at least soft (tin) jaws, to avoid damage to the shutter. Do NOT her
enlarged upper portion shutter at the point where it passes through the spindle. Doing so could cause it to deformation and subsequent problems with the function of the trigger mechanism.
Punch out the pin that holds the original rod shutter is triggered. After punching pin
Remove the old rod with its shutter spring. Do shutter insert a new weaker spring which
is supplied with a modified stem shutter interrupter. (This is not necessary.
You can also use the original spring). Into the groove in the trigger insert modified rod shutter
interrupter and carefully center punch, tap the pin back. Carefully make sure that the hole in the rod well centered on the pin. After inclusion pin check whether the modified shutter rod
interrupter may freely without rubbing around the pin shutter throughout his
range. If this is correct then we can insert this assembly back into the gun and tuck into
Body construction pin trigger. The same thing we do well to capture striker. After inserting two pins
return the lock to its original position by pushing on the rear arm such that its upper
surface parallel to the upper side body arms.
Now you need to check the proper operation:
1) Press the trigger to determine whether the trigger return spring shutter all the way to its
range. If you happen to have a lot of first running unopposed in the spring trigger (when
tilt weapons uppermost tab shutter spontaneously moves down and tilted
Zbani upside down vice versa), it is necessary to pin a file to reduce surface (edge) in accordance with the trigger
Figure 1. Simply subtract 0.1 - 0.2 mm.

2) Press the shutter button, hold it and push the tab breaker. Should be reduced and slippage
of the frame behind the capture of striker. Must may click and capture of striker must return to
original top position as when the trigger is pressed. Now again press the shutter button and capture
?dern?ku should again be reduced. If this does not catch a rod for capture
pin, it is necessary to remove material from the pad to the capture of striker according to Figure 2. Subscribe
very carefully for up to 0.1 mm. Always assemble a weapon as described above to determine
whether a weapon has been functioning properly. Carefully make sure that the pad has always been straight with sharp
edge and smooth.
Attention !!! This point pay great attention. If it happened, it does not capture rod
for the capture of striker and you should've assembled the gun and pulled, it would tighten the drums
mechanism, but he would not be run striker. The weapon would thus not go to disassemble. If this
it turns out, it is necessary to deal with removing the butt or grips to allow over
uncovered hole in the body of an arms push rod to catch the firing pin and firing pin so
run.

3) If you purchased a modified rod shutter interrupter and runs in which
screw drop the trigger, you must set it. Load the gun very end and put it into
front position. Push your finger on the striker who is captured for capture of striker direction
forward while pressing the shutter button. It must be free to move forward. Now take
1.5 mm Allen wrench and tighten the screw so that when you press the shutter button will not push
striker in the forward position. This means that the firing mechanism will not start. Now gradually
loosen the screw by counterclockwise for approximately 0.25 revolutions until at will
Press the trigger hammer to push into the front position. After one rotation of the screw always
Repeat the above procedure. The moment will already firing pin to retract into the front position,
so one last slightly loosen the screw speed of 0.25 to insure proper function
mechanism.
4) Assemble all the weapon and the conclusion and cover return springs. Now check whether the shutter rod
off reliably capture of engagement with the firing pin. Nat?hnut?m end to the rear position
Cock the firing mechanism. Press the shutter button (start the firing mechanism) and still hold it. Now
again draw a conclusion and return to the front position. Loosen the latch trigger. You should hear
click again and press the shutter cocking mechanism must go run. This procedure
Repeat at least 10 times and try more positions pulling the trigger (trigger offset only
a quarter of its running path, half etc.). If it happens that the firing mechanism is slack
and thus can not press the shutter button to start, it is necessary to reduce a spot on the capture of striker according to
Figure 3. Again, a maximum of 0.1 mm, and each test procedure described above, whether already
mechanism works properly. Carefully make sure that the pad has always been straight with sharp
edge and smooth.
5) If the shutter is modified rod with intermittent fault persists crash
?dern?ku in the shooting and all the above points are in order, it is necessary to slightly napru?it
(swig up by 1 - 2 mm) leaf spring which lifts the capture of striker. This adjustment is
but manifested as an increase trigger pull.
