Stormwerkz AR180B Adapters Back in Stock

Josh at just posted on Instagram that his Type 2 AR180B stock adapters are back in stock.

He has also improved them with the addition of a set screw to locate the receiver extension. That will be very helpful as getting the butt stock lined up when tightening the castle nut was a pain.

Check out these adapters as well as lots of other cool stuff on his website. Click here.

These are a perfect addition to the Nodak NDS-18S lower and if you install a pistol tube first, you can always build your gun as a pistol at a future date. Even if you build it as a rifle now. I don’t make the rules, I just follow them.

I have a few Lower Parts Kits left in stock with no plans to do a second batch in the near future. Now might be your last opportunity for quite some time. Shoot me an email at to order. $125 shipped, PayPal slightly higher.

Pistol Build Update

The goal for this pistol build is to make an AR180B upper that will work with an original lower as well as the NDS-18S.

I have had several readers ask if such a thing is possible and I know that it is, but until now I didn’t know exactly what mods need to be made. This upper will be my Guinea Pig.

I also have to avoid any problems with building an illegal SBR till I get a stamp for my Costa Mesa lower.

Here is my process as I see it. The 180B upper will not physically fit on an original lower do to clearance issues around the front pivot pin. I also feel that I can fit the stripped upper to my lower if it does not have a barrel installed. I will test fire the original lower with one of my original uppers and test fire my pistol upper with my new pistol NDS-18S lower. Never will the two fully meet till after the stamp comes back.

I am starting with the stripped lower that I got at the last SAR West show. I finally found most of the fire control parts and it should be ready for testing soon.

Just a quick mock up to show you what I hope it will look like down the road.

This will also apply to those looking to put a 180B rifle upper on their original lower.

First issue is the clearance issue around the front pivot pin. The sides need to be milled down some to clear the ears on the lower. The second issue becomes apparent as soon as you attempt to mate the two. The guide rod assemblies are not the same between the 180 and the 180B.


The NDS-18S gets around this by having holes to accommodate either assembly.


The original lower only has provisions for the upper holes. I considered drilling a new hole but decided against it.


You might think to yourself, why not use an original guide rod assembly in the B upper.


The rear sight is narrower on the B upper and that won’t work either. I am hoping I can come across a messed up original that I can make work or I may be forced to modify a B guide rod. I’m not opposed to modifying them but it looks like a royal pain to do.


Pistol AR-180B Build Begins

NoDak has released a second batch of NDS-18S lowers and I just got mine. Of course I am a fan of shorties so I am building a pistol. This time with a brace.

I used a Blade Brace and Tube kit from Shockwave Technologies.

I love it.

I used a Stormwerkz universal carbine adapter that required me to drill and tap two small holes in the rear of the receiver. Josh appears to be out of stock on the 180B type 2 adapter that would be a direct bolt on.

Still more work to be done on the pistol upper but I hope to finally get over this cold I have had for the last month and get some serious time in the shop this week.

I’ve also had several people contact me about shortening their 180B uppers and I hope to be taking those projects on soon.

Stormwerkz Charging Handle Install

Just finished installing one of Josh’s charging handles on my AR-180S Shorty and I’m really loving it.

A quick couple passes with an 1/8″ endmill to open up a slot and she fits like a glove.

This unit is very well built and reminds me a lot of the early Howa charging handle.
