Project SMG Special

This has been something I've been kicking around for awhile and I finally got started on it this week. Started off with this idea, why not take the positive traits from the SMG60, SMG68 and 68 Special, combine them while eliminating all the negative?

Disclaimer: No working SMGs were sacrificed

SMG60:
Negative: .62 cal and the receiver destroys itself where the receiver end cap screws in because its thin.
Positive: Full auto capability
SMG68:
Negative: Magazines destroy themselves with use. Semi only (personal view)
Positive: Beefier material for the receiver end cap, .68 cal
68 Special:
Negative: no longer uses stripper clips and a magazine.
Positive: Beefier material for the receiver end cap

The idea was started a while ago when I picked up a junk, cut up SMG60 receiver. Its a real shame what happened to this SMG. Its an early external air line marker with the screw in bead site. As you will see in a later picture, it is even missing the two gas relief holes. I have no clue how early this one was, the serial number was gone.


A 68 Special receiver is just a modified SMG receiver along with the improvements giving it extra strength for the end cap. The breach/magazine section is milled away to allow for the replacement upper receiver.
So why can't it be reversed back?


In progress (sorry for the horrible cell phone picture)


Milling completed on the new receiver.
I bead blasted it and re-blued the barrel. The barrel was very rusty and I'm pleased with how it cleaned up.


Here you can see the missing gas relief holes.


The receiver tube was also rusty. Here is the after shot showing how it cleaned up after bead blasting and bluing. The magazine has yet to be done but it shows how the receiver tube looked originally.


To do:
- drill and tap the new milled receiver for helicoil inserts to prevent the stripping of aluminum threads.
- Bead blast and blue a few parts
- mill the 68 Special receiver for the constant rate spring screw.


Wait you say...this is just going to be an updated SMG60? Its still .62 cal!

To be continued.....

I think its a cool project. I am assuming your aiming for a .68 cal smg.

AH-HAA! That's what you want pawls for. I have to say, very nice work so far, and a very interesting idea. I've almost perfected the .68 cal upgrade to my receiver and should be able to do work for ya in September. Ive just got a problem with breaking certain types of paint I want to fix.

What exactly are the purpose of those holes? Ive got SMG bodies with and without holes in the bottom of the breech. Assuming those are the holes you were talking about.

I'm guessing it was a modification in the later SMGs to make sure the clips fed properly?


More progress today over lunch break at work but nothing really to take pictures of. Drilled and taped the new milled receiver for helicoil inserts. The original plan was to make it a "convertible" so I could switch between front receivers. But I should be honest with myself, its not practical because I'm only ever going to use the .68 cal SMG receiver thats in the works.

So I'm thinking I'll end up JB Welding the receivers together to make it a permanent SMG68.

Thoughts?

I have a thought... well more accurately a question. How much do I have to pay you to get this done to my 68 special?

Maybe its just me, but I get the sense that he was hinting at something with this:

That being said, this would fit right in with the .50 cal "revolution"

I kid, I kid....

Well said!

So I lied, here are some pics





The brass tube is leftover material I had from when I made a barrel for my A-5 backup gun. The ID is .684 and it works great. I think I'm going to mic the OD of the tube and ream the receiver to match and make it permanent.

Edit:
Yes the tube is 3ft long
No I'm not going to leave it that length. I think 12-14" is enough.

Brass is good. SMG's are good. .68 is good.

I like this project.
