These two pistol braces are not compatible in case you were wondering. The tube diameter and bottom lug on the T91 stuff is larger in dimensions.
Next I started work on prototyping a straight 180B style charging handle for the BRN-180.
Made a quick one out of aluminum to check dimensions and function. Works fine with one exception. Charging the weapon with a traditional grip when the dust cover is closed causes the dust cover to hit your hand and somewhat inhibits a full stroke. A change in hand position will be required to eliminate this.
Based off some of my 3D printed tools I use in the shop I designed these Field Strip Stands for use with any AR180, AR180B, or AR18. I am going to offer these through AR180Parts.com soon.
Finally I have been strugling to locate fire control parts for some folks so I decided to try something radical and see if I could adapt a drop-in AR15 trigger into an AR180.
I got it physically located so it hit the firing pin at the right angle and cocks correctly when the bolt carrier cycles. I have no idea if it will actually have enough power to fire a primer. Range testing to follow. Ranges are closed in AZ right now. If it does fire I have to figure out how to get the safety to work.
If this doesn’t pan out I will still be able to use parts of this design to work up a set of anti walk pins for the AR180.
Finally I was able to get to the range last week before they closed to shoot my AR18 for the first time.
It has an interesting combination of features in addition to the stock. Black paint and a non-welded bolt catch pivot boss, both early features. Welded dovetail scope mount like the later blued model.
I have no information on this model and I am asking if any of you do?
I would be actively trying to buy this except the Corona Virus has hit my work and I will be home for the next 4 weeks without pay. I will be selling off guns and ammo to supplement my savings until we come out the other side. I hope someone in the family gets it as it is an interesting model to add to anyone’s collection.
After reading my last article I was contacted by Michael Vickers from Helston Forensics. He linked me a couple articles that he felt my readers and Jonathan Ferguson in particular would be interested in.
The first article is just chock full of interesting tidbits including Sterling AR-18S mods Sterling made, like a longer barrel to increase reliability, SAR-80 info as well as the connection to Mark Westrom, who went on to build the AR180B. Check it out Here.
Also mentioned in the article was the FAC-70. The Foote Automatic Carbine that Sterling considered making before taking on the AR-18/180 from Armalite. Michael sent me a second article that digs deeper into the particular weapon. The original article is Here.
I had never heard of this particular rifle before. I definitely want to learn more. It reminds me of the ARAK-21 line of rifles. I need to build a clone, don’t you think?
It was speculated that the Early Howa AR-180’s actually started life as AR-18’s that were first produced prior to 1967. They were blocked from export to the US and that forced Armalite to step up and make them in Costa Mesa. Later this initial order of 1000 rifles were converted to semi auto and then imported in the early 70’s.
I was contacted by Jonathan Ferguson who is the “Keeper of Firearms & Artillery” at the Royal Armouries Museum ,UK. He is researching a book on the evolution of the British Bullpup rifles. One of the early concept rifles used an AR-18 that was converted to a Bullpup.
From these photos I could tell it was a Howa but it had been scrubbed of markings. Jonathan was able to find a serial number on the flash hider and my earlier article led him to some interesting documents.
Assuming the flash hider had not been changed he found the the rifle had been acquired for testing in January of 1967. It was only later converted to a bullpup after testing had concluded. This is the first definitive PROOF that these guns existed before 1967! Very exciting news. This is the kind of primary source documentation that prompted me to start this site. It is critically important that these sources be found and the dots connected.
Jonathan has given permission to post this info but he will be going into much more depth on the subject in his book. I will certainly keep you abreast of any updates I get as to it’s release date.
