RS Regulate AK-300 rail system for Vz58 (pic heavy)

[BlackVoid]

I had a standard CSA mount with primary arms prism scope. Ability to remove spacer on PA gave lowest possible height over picatinny rail.

It looks like this.

Vz-304M is a QD mount/lower part of AK-300 system. it mounts on CSA standard base. 2nd part can be chosen according to the optics. I chose ACOG mount (PA is ACOG mount compatible). You can stake top part to lower part to make a one piece QD mount.

Step one.
Trying to put RS regulate VZ-304M on CSA base. And the first problem. Either my base out of spec or VZ-304M is. Rail is a no go.

Step two.
After some mallet treatment mount is on. But it is definitely not a QD at this time.

Step 3.
Removed with mallet again. Some visible deep gouges on the base where awesome american aluminium defeated poor european (or is it chinese?) steel.

You can see metal is neatly shaved. I think the problem was around 1/10th of a millimeter.

No adverse effect to the base, CSA QD mount still mounts fine.

Final result:

Regarding the mounting system itself. The only problematic part is adjusting the top part (and the scope) to be exactly aligned with the bore.
I used my Aimpoint red dot (which is mounted on piston rail) to align PA prism scope and then tightened the screws.

my final verdict. Very nice to have optics so low on VZ58, about an inch lower than CSA low height mount. not sure it's worth the money though.

I guess I can keep malleting it on and off until the base wears deep enough and it becomes a true QD mount.

RS regulate is fixing this problem after I sent my mount to them for inspection. They are now about to go into production with a updated version. They had built there side mount to be used with an American base plate I believe which is a little different from all the other ones.

I must have an American base plate mine fits fine.

My base plate is from CSA US store. It is most likely RS regulate QD mount is out of spec, bad luck, I guess.

This is excellent timing. I have been looking at these two mounts. With the standard csa low mount and primary arms scope, how was the cheek weld? And did you change mounts due to a issue or just for a change?

 

[BlackVoid]

It was a chin-wield. Refer to pic1 compared to Pic4.

Even with RS regulate I need a half inch magpul riser to get a proper cheek wield.

The lowest with Aimpoint/Aimpoint rings and King gun railed top cover

How solid is that dust cover mount? I have heard some people have issues and others say they are great.

 

[paske]

No complaints, and it makes the gun a bit firmer.

and i believe they mainly work with the CZ858 not the CSA vz58 because of the receiver which differ a little

I have two dust cover mounts 1 Corwin-arms and the other is the gun king mount like in the pic above both have been great. The both fit fine on eather vz.58 or cz858 (for me anyway ).

I like the look of the dust covers, but I enjoy the idea of quick removal. My problem regardless will be the height and size of my red dot

Speaking over hights!!!!!! Which is a hip-weld

Size??? Low, small and co-withness

Quick removal and magnifying.

Lmao, the hip weld looks awesome. I am a 80's action movie fan. In appearance the micro on a upper handguard looks the best. But I'm not a fan of the eye relief it gives.
