REVIEW: Gen 2 Rauch Tactical VZ58 Buttstock Adapter
DSC01146.jpg


Rauch Tactical was kind enough to send me his newest version of his M4/AR15 Stock Adapter for the VZ58/CZ858 Series of rifles. I have been using his 1st Generation of stock adapters since last year and have been impressed with the quality. I had given the designer some input into both Gen 1 and after using Gen 1, suggestions for the Gen 2, so I was looking forward to it's release @ SHOT Show 2010.

Fit and Finish
Fit is tight and exact, the way quality firearms parts should be. Finish is a black hard anodized.

Construction
6061-T6 Aluminum.

The threaded adapter cup is much thicker than the Gen 1 version. Thread pitch is also better to reduce likely hood of the machine screws stripping if you were to mortar the stock while clearing a stoppage.

Installation
Remove old adapter plate. Put new one on, bolts on like any other rear plate with a single bolt. Threaded adapter cup attaches with two machine screws at one of 4 heights depending on your application. Those running iron sights will prefer a lower setting, while using optics will necessitate using of the higher two. I am using the 2nd highest setting to accommodate my Aimpoint H-1 Micro on PRI front gas cover.

I mounted a milspec buffer tube and LMT SOPMOD stock, the same setup I had on the Gen 1 adapter.

Price
$65 plus the cost of whatever extension/buffertube and stock you choose.

Availability
I am told they are in stock now at:

http://rauchtactical.com/

Design
-Sturdier construction
-Sling loops on both sides. I moved my Vickers sling to the sling plate to give it a whirl, normally I run the rear of my sling through the stock or on an ASAP plate.
-4 settings vs. 2 settings. Obviously this will accommodate more end user's setups. I had been using the lower setting on the Gen 1 combined with a riser made of rubber stereo insulation. The 2nd highest setting of the new adapter is the perfect height for me with no riser.
-Inline (Rauch Tactical) vs. Angled (Stormwerkz and other companies). I prefer a stock inline to the bore, rather than having the recoil coming at an angle.

Conclusion
RT has done it again with a great product at a very affordable price. I would recommend the product to anyone looking to upgrade their Gen 1 or put an AR15 stock on their VZ/CZ.:cheers:

Aren't folders already available? I thought they came factory on a specific version of the rifle. Don't quote me though.

Yes, the rifle comes with a side folding wire stock that is fixed length and uncomfortable. He means a AR15/m4 side adapter that also folds. I believe a couple companies have this in the works.

what he said, i love the compactness of the stock folder, but i dont have chipmunk cheeks so i get little to no cheek weld, if i hold the mag as a grip i can get close but it just a bad weld.:(
 
Some of the wider ones like the LMT SOPMOD, ACS etc may have an issue folding but overall most will work.

Regarding the hinge system you can still adjust the height of the stock with the hinge and an added bonus is that you will be able to mount the hinge to fold to whatever side you want, the hinge will be ambi as well.
 
I received the RT multi-height adaptor today and installed it this evening.

Nicely packaged as removed from envelope:

The insert to fit factory receiver hole:

Adaptor plate in place. Needed a couple smacks from a rubber mallet to get it seated tight. Note the 4 possible stock height positions. The larger of the three included socket cap screws is what holds this to the rifle via the threaded insert:

A few observations:

- I found that the top two stock positions make the iron sights unusable for me. The third-from-top position mimics the original comb height fairly closely.

- with that stock fully collapsed it is about 1" shorter LOP than either the factory fixed or folding stocks. Obviously, you can increase the LOP to much longer than factory. One notch out on the 6 position stock has the same LOP as factory.

- with the stock fully collapsed the square corner on the top of the adaptor will come into contact with your nose if you like to shoot nose-to-receiver-cover.

Range report to come tomorrow, if all goes according to plan.
 
The height you use is really gonna depend on the combination of three things:

1. The shape of your face. Everyone is different and we all have different comfort points.

2. The stock you are using. Keep in mind if you have a face like mine and you use a stock like Big Red's then you may set the height lower then if you are using a standard M4 type stock a CTR etc.

3. The optic and or mount you are using. If you are like me (and you don't have to be :D) then the irons are expendable when using a quality optic. I trust my aimpoints enough that I don't really care for irons so a higher mount is not an issue. Others may have different opinions and thats fine.

One thing I will tell you, the higher you mount the stock will directly effect the control and feel of the rifle when firing. At the highest stock setting you will have the least amount of muzzle rise and cheek slap. But most important is your feeling comfortable. So before you loctite everything down take the time to get a good feel for the gun at different stock heights and be sure you feel good with your optic/mount choice.
 
I got a chance to put a couple hundred rounds through my rifle with this adaptor mounted today.

A few thoughts:
- while not in line with the bore the straight line stock did seem to reduce the muzzle rise on recoil.
- 2nd position from the bottom works well in approximating the original comb height. It may be a smidge taller, but not so that it makes a difference. You may want to use the bottom holes if you have a ham for a cheek.
- it didn't fall off, and that's a good thing. Seriously, I'm not going to jump on it or drive a truck over it so I can't really say how strong it is other than "sufficiently".;)
- the sharp corners and edges have to go. I'll be taking my Dremel to it so I don't poke my face with it when shooting with the stock fully collapsed.

Overall, I'm pleased with the RT multi-height stock adaptor.

I just got mine put on today, and it is the heat. Unfortunately the pics are on Big Red's camera. Because I'm shooting irons, I put mine on the second level from the bottom, which I think is the same place Stevo put his. In recoil is much more straight back and in combination with Rauch's new muzzle brake, there was virtually no muzzle rise. I used a standard 6 position commercial tubed AR stock that was recycled of my own AR. I wouldn't recommend that using that stock, if you could avoid it. It reminded me a lot of shooting my East German side folder AK in Iraq. That is, Bang, Ow, Bang, Ow, Bang Ow. I felt like I was going to leave the range with a shiner on my left eye. I've shot Big Red's with the SOPMOD stock and it is quite comfortable, so I think spending a little extra and getting an enhanced stock is a good idea.

All in all this adapter is a great piece of kit, and well worth the money. Go buy 2 right now.
 
That's the same stock/tube combo I have on mine and didn't notice any slap at all. My face must have more padding than yours.
