New E-Mail Address and a Cool Tool on GunLab

In addition to coughing up the cash to renew my domain and my wordpress subscription, I also added a new email address.

Rick@AR180S.com

You should all be getting your correspondence from me there (if I did it right).

Feel free to drop me a line there if you want to share your AR-180 information and if you have any questions.

If you are not already a subscriber, please drop your email in the box on the right and you should get added to my list.

Chuck at GunLab.net has just put up an article about a cool fixture used to machine the cam slot in the bolt carriers of early AR-18’s.

Go give him a read. I admire the skill of the tool and die makers that built these guns. True masters and a skill that this country is loosing.

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.

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.

 

 

 

The First 1000 Howa AR-180s

In the world of AR-180 collecting one of the top prizes could be considered the early Howa AR-180s.

Several notable features are readily apparent but some subtle clues to it’s origins are hiding just below the surface.

The most obvious feature of the rifles is the placement of the serial number, on the upper receiver as opposed to the lower.

The second is the 180 degree swing safety, which is unique to the Howa.

Some examples show a distinct misalignment of the 0 in the 180. This our first clue that these guns started life as AR-18s.

Further clues can be discovered when looking at the bottom of the upper receiver.

HowaUpper1HowaUpper3 HowaUpper2

It is obvious when compared to the underside of an AR-18 that the part that held the auto sear has been removed.

The firing pins also look different and it looks to me like these Howas used modified AR-18 firing pins.

The really interesting thing about these guns is when they were actually made. I think the evidence makes a strong case for 1967. Much earlier than many thought.

The first piece of the puzzle is an article in the January 31. 1966 issue of U.S. News & World Report. It states that a provisional agreement was reached and Howa would undertake the first mass production of this rifle.

820-page-001

Japan then, during the Diet session of 1967, introduced the “Three Principles” which forbid the exportation of arms to nations in active conflict. Anyone remember what the US was doing in 1967? In southeast Asia? That’s right the Vietnam War. Howa would not have started production of a rifle they could not export so it makes sense that they were built sometime between Jan ’66 and the passing of the law in 1967.

Yet another clue, and the one first postulated by my friend and mentor, Rich, was that the earliest scopes sold in this country were originally matched up with these first 1000 Howa AR-18s. These particular AR-18s were known to have matching serial numbered flash hiders and Rich speculated that the scopes were matched as well. All the first scopes have serial numbers that start with 67 and do not go above 1000. After the rifles were banned from importation, ArmaLite ramped up production themselves and since there was no ban on the importation of the scopes, there separated from the rifles and sent to the US. These were sold as accessories with the Costa Mesa rifles.

I would like to thank all the generous folks on the retro forum at AR15.com and all those who have helped with the gathering of this information.

Like I said when I started this site, I want it to be a central depository for information about these cool guns.

 

 

Original ArmaLite Shipping Box and Parts

I recently traded some goodies with one of my readers and ended up with this awesome piece of history.

It would appear that someone ordered some spare parts for their AR-180 and then it just sat around, unused.

I believe it was sold recently on GunBroker as a package with the gun and I was able to do some horse trading for it from him.

This is the stuff that really gets my juices flowing. I almost love the history part of this hobby more than the shooting. Almost.

Shown here with what is left of an AR-180 Scope box.
