In just a couple of years (or less?) that gun will be C&R eligible. if owned as a C&R it can be transported without having to notify atf.

Just think of antelope hunting or hog blasting in a free state.

Been a long time since I saw an upper like that!
Have you shot it and how well does it work?
Very nice collection for sure!

I was just thinking the same thing. Any chance you'd take off the HG's to see what the gas system looks like OP? I bet it's something similar to the LaFrance M16K gas system or at least a pig-tail set up. Once again, congrats on your latest addition to your collection

At the request, heres info about the gas system on my shorty. I also included a copy of an article of a company claiming to have invented it, but its my understanding it was developed much earlier by groups in Asia as a way to combat the unpredictable reliability of the shorties, if i can find that article i will upload it here also.

Looks like a very interesting science project!

- What is the length of the barrel?

- How is the HG cap attached to the FSB?

I think tack welded. The thought of cutting 6 hole hgs

The threading begins at the end of the end cap. I am able to hit soda cans at 100yds no problem with iron sights with this setup.

So the HG cap is held on by the FH?

How long is the barrel?

Appears a pistol gas system could be used.

Dam thing has a catalytic converter! LOL.
That is the most awesome thing I have seen in years.
I never knew it existed. I have to find one now..

Thank you so KINDLY for sharing that with us.

^^^^ Ditto ... So green with envy looking at those lowers with the auto-sears

As i alluded to before, you cannot use a pistol length gas tube to make a setup this short function. Even if you can iron out the reliability, the gun will literally eat conventional gas tubes, the erosion is very bad. Essentially what must be done is a blasting chamber created/milled out of steel, this will give the gas a chance to build up pressure to cycle the bolt evenly EVERY time and is much more durable than the conventional stainless tubes. More details and pictures to follow regarding the design and dimensions of the "short shorty" upper.

Why are the auto sear springs all installed behind the selector? They should be on the front side in the slot.

I have never had a problem with it in the back of the selector but having the sear pins in front of the selector will wear out the actual sear spring because of the constant movement of the selector. Also, having the sear spring in front of the selector will cause too much tension on the contact point of the actually slot of the auto sear pin where training students to dismantle the trigger group, selector, and auto sear itself. Pushing the auto sear pin
out with the auto sear spring in the front positing will cause damage to the upper part of the auto sear sear spring it you don't remove the actual selector. (Pics posted with 357 Magnum AP Round for scale)

Regarding the upper:
The barrel is under 8.5 inches. The barrel end at the handguards cap at 7.8 inches, just under 8 inches and the threads start, but there is a small ledge for the end cap to seat on as seen in the picture. Very simple. Make sure to modify the sight base to so the handguards fit in. The best setup i have found is to use the colt 6 hole handguards, cut'em up to fit the upper, and i buy Colt HBAR barrels and cut them down, it will give you the best performance in the durability department because everyone loves to dump a 100 round mag at night with this thing, the flames are longer than the gun!

In front of the selector is the correct place for it, behind does not always provide the correct tension to ensure positive operation.

The leg of the sear spring sitting in the slot of the selector will not wear it out.

Yes, sometimes the sear pins can be rather stiff to remove but, that tension is what prevents it from walking out.

If you put the selector in the safe position it makes it easier to remove the pin. They will come out with a little finesse and a light tap.

There is no reason to disassemble the sear itself, it only causes unneeded wear. If it needs replacing, they come as an assembly.

Ham handed students using brute force can damage anything. No offense but if you're going to teach students, teach them correct assembly.

When I see the auto sear spring behind the selector or, the hammer spring under the trigger pin it is a sure sign someone has done unauthorized disassembly of the lower and didn't know how to put it back together correctly. Not trying to be an asshole but, I've been doing this for over three decades so, take it for what its worth, YMMV, etc, etc.

I do like the barrel work though,

That one lower with the .357 round for scale needs some JBWeld or something. Doesn't look quite right.

Posted: 10/10/2016 3:03:25 PM EDT

[#32]

.In MY experience, the "correct" or preferred way provides to much tension when firing different calibers (45, 9mm, etc) and causes unneeded stress, this is my experience only. However i will say that i run my guns hard, as they are primarily designed as tools and I often let friends shoot them (and they never bring 100 rds, they usually bring 1000) so they routinely get shot until the gas tube melts in some cases. If you have access to the ammunition and can put a M16 under significant stress, the current location of my sear actually outlasts the recommended service life prescribed by the army. Remember, when you have students qualifying, they arent doing mag dump after mag dump, and in this scenario any m16 should hold up if its worth its salt regardless of orientation of auto sear spring. When you are really testing any weapon system through hard sustained fire in adverse environments, what works and what doesnt can be determined very quickly.

Posted: 10/11/2016 12:20:27 PM EDT

[#33]

Our experiences obviously differ,

I work on high round count weapons which are .mil issued "tools" and have been at this long enough to determine what does and doesn't work.

There is no prescribed service life or replacement schedule for the auto sear in any TM. You simply replace it when it becomes unserviceable.

While I am all for people being able to perform detailed maintenance on their weapons, there is no reason to routinely remove the auto sear from the lower. Even if the hammer and trigger are removed to clean and lube, the sear can be adequately serviced remaining in the lower. If your students are primarily shooters, my original comments apply and probably account for some of the failures you are seeing.

If your system works for you, enjoy.

Changing the focus- What type bayonet is that in the first couple pix?

Looks like a K-bar shaped blade and M1 carbine type leather hilt/ handle?

Never seen one like that for the M16.

thanks.

Latest Project. Ultimate Retro gun (IMO).

Yes, that is an original carriage, of which only 1500 were originally made.

[#36]

Well that's just plain silly right there. Display piece or working mini?

Posted: 10/20/2016 11:57:59 AM EDT

[#37]

The blade is a Rock Island Prototype "Sniper" bayonet. I had a link to some info on it some moons ago I will try and find it again. The mini was at the creek this year.

How did I miss this thread?

That shorty is pretty damn cool. Eagerly awaiting more info on the gas tube.

It reminds me of the kind of stuff LaFrance used to do but simpler.

You sir have me wanting to do a retro PDW now.

Aww com'on brennon272!

Anxiously awaiting more details on that gas tube.

Posted: 11/16/2016 9:32:00 PM EDT

[#41]

I was looking at the pictures that brennon272 posted and got to thinking - - - Heck I think I can sort of make that with some of the stuff in my spare parts bin.

I used a pistol gas system along with a 8 inch barrel.

It must be a 8 incher, 7.5 inch won't work. KAK makes a pistol one in their value-line that is only $95.00.

https://www.kakindustry.com/ar-15-parts/upper-parts/barrels/5-56-mm/8-0-inch/contract-556-8-inch-pistol-melonite-barrel

I have about 200 rounds through it right now without any issues. Used one of my SBR lowers. Started with a H3 buffer, but found that it works fine with a H2.

Fun little blaster. Reminds me of some of the strange science projects I saw running around Bragg early on during the GWOT.
