Very Early Costa Mesa AR-18

Friend of the site Andrew Huber had the opportunity to look over more than a few weapons at the West Point museum and one of them is a very early example of the AR-18. Serial number 057.

Lets look over a few of his pictures and compare those to later production examples.

The most notable feature from this angle is actually what it is missing, the reinforcement around the front of the mag-well. While not as strong I think it has a sleeker look to it. Next would be the roll marks. They certainly made a few changes when they went into production. Unlike the first prototype that is shown in early literature this example uses the traditional folding stock retention stud. Like the first prototype this one does not have a dovetail scope mount on the upper receiver.

It also features an inspection mark on the upper that I have never seen before.

Do you see any other interesting details that I missed?

Make sure you respond, share and subscribe. I’ll dig into the other side of the receiver in the next article so stay tuned. Awesome stuff and I can’t thank Andrew enough for doing the hard work gathering these pictures?

SAR West Show Next Saturday

Hope to see anyone who is attending the SAR West Show next Saturday in Phoenix.

I’ll be the guy walking around with my AR180S Pistol with a folding Tailhook brace and my Pistol grip!

Stop and say “Hi!” of you see me.

AR180S Pistol Grips Ready To Ship

Well I have 3 ready to ship.

I have reworked the model and done modifications to my printer and I am happy with how they are printing now.

I have also decided to put them up for sale and will print and fill orders as they come in. That might take awhile to fill as they take quite some time to print. 18+ hours to be exact.

These can certainly be used as is but really need to be sanded, polished, possibly even painted.

Here is an early prototype that I sanded and rounded the edges then polished.

First 3 will ship right away, first come, first served. Just click on the link at the top of the page to take you to the Shopping Cart.

I am really looking forward to getting some pictures of how your pistol grips turn out!

As always use the “Contact Me” link to send me an email if you have any questions.

 

 

Reader Pics: New Sharpshooter Kit

Got an email the other day and I knew y’all would be interested in it.

A brand new Sharpshooter kit.

 

This one is packaged as coming from Timberline Hawk and differs in construction from my example. The hand guard cover is improved by the addition of Velcro to allow it to be removed easily. The butt stock cover is the real pain in the ass to install. If I made a new version of this I would certainly use Velcro for that as well.

Just for fun I am including a pic from the movie Daylight’s End showing a Sharpshooter in use.

 

Lost ArmaLite Part 2

The most obvious and interesting thing about serial number 021 AR18S is the hand guard. Lets have a closer look.

The hand guard is made of wood and is the only one I have seen like this. What wasn’t apparent until these auction photos surfaced was that it is made of multiple pieces and different materials.

The upper hand guard is much taller than a traditional AR18 part almost making up the entirety of the hand guard itself. This setup does not use a metal retainer like other 18S models do. No picture are shown of the top but I am going to guess there are vent holes and ribs just like the standard pieces.

The left side shows some damage. The right side has a crack that might turn into a break like this.

The front of the hand guard was the most interesting to me. It looks like a different material was used, possibly fiber board. Hopefully something that can withstand the heat. This piece appears to be pinned and glued to the main hand guard and is retained by a protrusion on the front sight base. we will explore the FSB in another article.

What I can’t be sure about is if this piece is slotted so the hand guard can be removed in a normal fashion or if the front sight base must be removed first and the hand guard slid off the front.

The lower piece looks to be made of yet a different type of material. I’m guessing Micarta.

It is retained at the rear my the lug on the trunion but I can not for the life of me figure out how it is attached at the front. Looking closely at the first picture in this article you can make out ribs cut along the bottom. I first thought it might be held on with a screw into the FSB but I don’t find one.

I welcome any comments about things you see that I have missed.

And if anyone wants to buy this gun and let me inspect and document it for posterity just head over and throw in a bid. I’m staying out of this one.
