"Hush Puppy" Rear Sight Wings & Update

[dvelleux]

Bill,

I sent an email with all the needed reference files off to the ATF just a moment ago. I made a very thorough explanation of what everything is, and the attached images show everything is as I stated it to be...

Now we sit and wait...

Folks,

I have been having some chats and doing some reading offline about the shoulder stocks. Seems very few were made and fewer were used in the field. In reading from a book by Kevin Dockery, he stated a few SEALs merely attached the pistol to a lanyard and slip the lanyard over their necks...

So should I even attempt to make drawing for the shoulder stock at this time?

 

[dvelleux]

Folks,

My, how our government works at times. Heard back from ATF regarding the faux suppressor; they want to see a physical copy BEFORE they make a ruling. Okay then, may be a short wait until I can save the funds to do so. I know of at least one existing faux can, but I would never ask a person to potentially lose something as the ATF examines it. So, we wait a bit, but everything else is still ongoing...

 

[BMCM]

Ask then if a prototype model at 1:1 scale made of composite material would suffice to make a determination. I imagine something could be whipped up quite cheaply. Looking at your drawing, it appears the "can" is nothing more than a chunk of pipe. No baffles, no liner, essentially a barrel extension so I don't see any reason a detail model wouldn't do unless of course the ATF wants to conduct live fire testing and measure decibels

Cheers
Bill

Bill,

HAPPY NEW YEAR!!!

We can discuss that offline, but I think a 1:1 model, with the recess in the front, would fill the bill. Just tell them this is a prototype and the real item will be of aluminum for strength...

 

[dvelleux]

Folks,

HAPPY NEW YEAR!!!

And I do feel it will be a great year that the Mark 22 Mod 0 "Hush Puppy" will truly be reborn, basically fifty years after it first saw use by the SEALs in Vietnam...

Based on input from others, I made the "executive decision" to hold off on the shoulder stock plans for now. I do realize attaching the shoulder stock to the pistol will instantly make it a Short Barreled Rifle (SBR) and I do NOT wish to tangle with the ATF, hence for me, I will only create the drawings at a later date...

BMCM is about to send me two chamber plugs he created from Delrin, with two different types of O-rings, to see which works best. BMCM is also working on a mold for the back end cap plug. He will be come the source for chamber plugs, back end cap plugs, and potentially muzzle plugs, once we make up a prototype faux can to send to the ATF for their determination if they will even allow the muzzle plug on a faux suppressor to start with...

So, in summary, the slide lock is the ONLY part actually left to be made, and that is in the works right now. The remaining needed parts (front sight, rear sight wings & elevation screw, faux suppressor) already have been made. Soon anyone will be able to recreate the "Hush Puppy," to enjoy and pay tribute to those SEALs who put themselves into harm's way while carrying it...

Another update hopefully soon...

Folks,

Received a Delrin chamber plug from BMCM today. It worked PERFECTLY, but extraction was a bit of an issue, though a couple fo changes to the rim thickness and the wb diamater should resolve the issue entirely...

 

[dvelleux]

Folks,

Anyone know of a decent web site to learn how to make a holster? I wish to make the holster for the Hush Puppy with the faux can attached. I have made holsters in the past, but they turn out less tha I want them to be...

 

[dvelleux]

Folks,

Am posting a few new images of the chamber plugs done by BMCM. Later this week, else early next, I am going to head to the gunsmith to pick up the 39-2 slide he worked on to cut down the barrel bushing to the proper "ring" size, then silver soldered into its correct place to allow a 5" barrel to operate and be removed for cleaning from the slide...

Things ARE progressing. The first replica should be done shortly...

 

[dvelleux]

Folks,

Just heard from the gent who is making the rear sight wings. He will be making a new batch this Saturday. I made a small modification to better fit the existing Second and Third Gen rear sight, to allow the windage adjustment screw to have more and better access. Yes, as I stated on the first post of this thread, I do not wish to do this, but it needed to be done. I truly am not worried, since there still will be enough "meat" on the wing's rear edge for strength and durability...

Launch date is getting closer. The chamber plugs are perfected and ready for production. We are still working on the back end cap plug for the suppressor. A 1:1 model of the faux suppressor will soon be made up and sent to the ATF for approval...

Exciting times indeed, folks...

 

[dvelleux]

Folks,

Spoke on the phone the first time with BMCM regarding the Accessory Kit parts. His Delrin chamber plugs are ready for production. We spoke at length about the muzzle plugs, the barrel caps and the back end cap plugs. The muzzle plugs will be made from a sheet of a white vinyl-like product, punching them out with a gasket cutting tool. With both the barrel cap and back end cap plug, we basically came up with the idea of creating something like a bullet mold to form the external shape of both items, while there will be an internal insert to create the inner portion of the barrel cap. BMCM has some ideas he wants to try regarding the actual material itself. He is also going to create a 1:1 copy of the faux Mark 3 suppressor with the recess, to be sent to the ATF for their legal determination...

By Wednesday, I should be picking up my 39-2 slide with the silver soldered "ring" bushing. I shall also discuss with the gunsmith who to go about creating the 3-D model of the slide lock for testing and verification...

Keep the faith...

kwill1,

Since you own an original barrel cap, are you able to post some images here, and perhaps give out some dimensions on that item? Thanks in advance...

 

[kwill1911]

See post #12 for a picture of what I have. Dimensions:

Muzzle cap:
1.25 diameter
0.375 Thick
0.25 diameter of depression
0.125 depth of depression

Barrel cap:
0.75 OD
0.5 ID
1.00 long
The material is 0.375 thick so the depth is 0.625.

kwill1,

I got my mind wrapped around the muzzle cap disk. Guess the Navy felt a much thicker disk would be better at keeping water out of the suppressor...

With the barrel cap, I am confused, which is not too difficult for me. Does the interior of the barrel cap have "padding" to more or less cushion the threaded barrel in case it was dropped muzzle down? What is the actual material thickness? I guess it is 0.125" thick, but what IS the actual material? It looks to be like a rubberized thing from the images, but perhaps not a vinyl substance.

We will get things troubleshot yet...

 

[kwill1911]

The barrel cap seems to be fairly ordinary rubber. There is no padding beyond the material itself. Note the muzzle cap has an annular ring so it can be press fit into the tube. Reading the original patent may help. If you don't have it I can send a PDF.

 

[BMCM]

Kevin,

Regarding the muzzle cap....

Any guess as to what the material is? Based solely on some of the pictures I've seen I'm thinking silicone rubber.

ETA: Can you post a picture of the muzzle cap edge on showing the annular groove?

Cheers
Bill

 

[kwill1911]

Kind of quick and dirty but:

I don't think the muzzle cap is silicone; just plain black rubber but ??

 

[BMCM]

Not the barrel cap...the can muzzle cap, any guess as to what compound that is? Kinda looks like silicone that has yellowed with age to me.

Cheers
Bill

 

[kwill1911]

Polyurethane, according to the patent. I think that's the original color.

 

[BMCM]

Ahh good, urethane is even better. Two component pourable compound can be had easily. Looks like I need to explore crafting another mold of some sort.

Does the patent describe the firmness of the material or Shore rating ie. shore 60A is comparable to car tire tread.

Cheers
Bill
