A New AR-180S Upper is in the Works

A new AR-180S Upper

I just wanted to make a quick post to show you some pics of my progress today.

This is the barrel I found at my local gun store after I stripped the front sight base and extension. It is unmarked but I think it might be an Olympic due to the.750″ cast front sight base. I cut it off right behind the gas port.

Here it is between my first shorty and a full size 180B.

An finally, a shot from the front showing the barrel profile. I tried to imagine what it would look like if Armalite had released a 180B pistol or SBR version and emulate that.

Still to be done. New OP rod. Drill gas port then parkerize the barrel and flash hider. I also need to make another flash hider and end cap. Maybe I will work on doing these in CAD so they can be reproduced more easily.

What’s Been Happening at AR180S.com

What’s been happening at AR180S.com?

Just busy as all get out.

Shipped out the first batch of AR180 Lower Parts Kits. I hope that leads to more AR-180 enthusiasm as more NoDak lowers get sold and more Stormwerkz adapters get sold, and finally uppers begin to come out of the GunLab. I’m sure that there will be a time soon that you will be able to build your own AR-180 from scratch.

Chuck has a few extra Bolt Hold Opens and I will be posting those up for sale individually after I get them in my hands.

Work has me traveling all over since one of our trainers left to teach at a community college and I am filling in for him in the Pacific Northwest. Hopefully we will get a new person to take over that territory and I can stay closer to home.

New AR-180S

I am looking to build a second shorty upper and I hope to bring you details as the build continues.

I have a 180B stripped upper and found an HBAR AR15 barrel as a starting point. This will allow me to turn the profile to exactly what I want and not have to sleeve the barrel under the gas block like my first one. I will also be extending the hand guards a fraction of an inch to match the original AR-18S lower hand guard that I have. This will become the standard length an will allow me to design an endcap and they won’t have to be custom made for each gun.

You can see in this picture how the hand guard is long enough to retain the reinforcing rib.

I am also toying with the idea on an even shorter version with hand guards cut off at the first rib.

This matches the description of the AR-18K but I have never seen a picture of said weapon.

If anyone has any info about these short versions, please drop me a line. I would love to chat about it.

AR-180B Shorty Project Pt. VIII: The New AR-180S

A quick update on the AR-180B Shorty Project or what I like to call it, the New AR-180S.

I had some time to attend a therapy session in my shop this past weekend and I have to say it was successful.

I have been bothered by the hand guards on this gun from the very beginning and I finally decided to do something about it.

I have tried and failed to make a retainer for the hand guards out of sheet steel like the originals. I’m good with my hands but I am no body man.

I have long thought about machining a retainer from aluminum but a figured in could only be done with CNC, which I don’t have.

I decided that I would throw caution to the wind and try to mill it manually on my mill. Whats the worst that could happen?

For reference, this is the method I am trying to emulate.

My original, and always temporary method, was to take the end of the cut off piece and glue it inside the remaining piece. It has already broken once and was coming loose again.

I started with a piece of 6061 and laid out the shape a needed.

D6711AE4-0FDA-47E8-BD48-2A513E2D05CB_zps2r2pdecv

I squared up the sides then drilled out my holes and checked to see if I had my dimensions correct.

I then moved my end mill down to the depth I wanted and followed my layout lines using both knobs at the same time. This is where the therapy came in. It took a lot of concentration but in the end I think I did a pretty good job, if I don’t say so myself.

I made sure it actually fit the hand guards.

I then flipped it over and shaved it down to .035″, the same thickness as the steel retainer.

Then I trimmed up the sides on my porta-band.

And finished up with some flap disc and file work.

A final test fit.

Since I have no way to anodize I shot it with my favorite substitute, Rust-Oleum Dark Grey Primer.

And here she is an all her glory the New AR-180S!

I can’t tell you how much better the hand guards feel. They have always moved a little and never felt secure.

Now they are rock solid.

Fingers crossed that I can get some time this weekend to go shooting. I hasn’t had a round through it since it was a pistol.

 

 

 

AR-180B Lower Parts Update!

Just got my sample parts from Chuck and I must say, they look awesome. I really like the light park job that he has done on these and the quality is outstanding.

The Bolt hold opens need a bit of a tweak on one bend so that is holding us up a bit. They should be ready to go shortly so get your name on the list by emailing me at rkelley91 at gmail dot com and I will put you on the list.

These parts along with an AR-15 lower parts kit will allow you to populate a Nodak NDS-18S lower without having to buy an AR-180B first.

You can then use that lower on your original AR-180, AR-180B, and Vulcan V-18. Using one on an original 180 will allow you to use standard AR-15 STANAG magazines instead of 180 mags.

Pricing is $125 per set, shipped and insured in the continental US, Alaska and Hawaii slightly higher. No international sales at this time.

Now for some pics of this set in my SBR lower.
