Primary Arms 2x prism on RS Regulate rail?
« on: December 04, 2021, 12:25:09 PM »
Anybody run one of these on an RS Regulate rail?

I installed it on mine, but I'm concerned it may be too long and get banged up during ejection.

Pics are helpful.  Add a killflash to protect the glass if you're really worried.

I have a 3X on mine, never gets hit with empties. I went with the ACOG upper though, to get the optic lower.

Please let us know how this runs.  This is one of the ONLY places that discusses the VZ 58. 

Knowing how this one does at close range is important.  I don't think the 3X is a 'CQB' option. 

It WOULD be nice to be able to run a multiplier as you can on some AK mounts.  I don't think an option exists to do this on a 58.

I don't clear rooms with this, lol! It's a range shooter, never has missed a beat. They absolutely love VZ58s on the AK Files, good place to hang out for all kinds of discussion:) This CQB was literally the only rifle Czechpoint had in stock when I had the cash ready, plus I like short rifles. I had a much taller CSA scope base, before the RS Regulate mount, so I put a straight M4 adapter on it to help with the cheek weld. It now has the original angled adapter back on it, with a perfect weld.

I'll rephrase - COULD it be used at close range well?  (I understand some of the limitations, but I DO believe that the 3X is a NO GO for close range or home defense. 

See:  https://youtu.be/ENsxyT8iCM0

Thanks.

I wouldn't use a 3X inside, no way. It's a great 100 yard plinker though. I would use a red dot if this was intended for inside, or just remove the optic.

Don't know if these have flip up lens cups, but if so close the front one and shoot both eyes open...  Quicker albeit a little less exact than offset BUIS, but adequate for civilian self-defense needs.

Never thought of trying that, makes sense :)

Just tried this, works great!

The key problem I see with the VZ 58 is that you CANNOT use a 1X with a 3X magnifier - not enough room.   There ARE some options with the AK to do this. 

We must mount another optic.  That is also why I asked about the 2X and close range.

I think most folks now realize that red dots w/ magnifiers are no longer the best option and why moving to LPVOs.

Most folks might want the flexibility of a variable optic and that's fine especially for a range gun.

Not me.  I'd like to keep the weight down.  If I throw on an optic magnifier for 3X I am now extending my range considerably, and I can 'go back' to a lightweight carbine for most of my work. 

Yes, there is a tradeoff, and the LPVO will perform better at distance, but I don't want the weight.

Yeah, LPVOs are great on certain guns for certain applications, but they’re heavy, and on a Vz58 they’d get constantly dinged by ejected shells.

I’ve found the PA 3x prism optic with the ACSS reticle to be just about perfect for the Vz58 in x39, compact, lightweight and accurate out to 300 yards (maybe even beyond if I had a range to shoot farther). That package makes for a really handy little brush / hunting rifle.

3X is not good for CQB distance.  Why I'm asking about the 2X.

A heavy system on the VZ eliminates some of the guns primary advantage.

LPVOs are w/in a quarter lb of magnifier and micro -- less w/ full size red dot -- or ~25%.  And yes, LPFVOs are not ideal for the Vz58.  That's why if your needs mandate it, you're better off to look at other systems with full length picatinny top rail.

If you're mounting anything on a rear side rail mount you are eliminating some of the Vz58's weight savings, and much if using any of the CSA steel side rails.

The Vz58 is a carbine suited to carbine roles -- in no small part due to the ballistics of the 7.62x39 round.  The second you start adding magnified optics to it, you're forcing a carbine into rifle roles.
