I would like to do a parallel build with one or more members, more is better.
Not the traditional RG-G design. More of a Rat Gat.
Based on the Ruger 10 22, with 5 stock barrels and bolts.
I picked up 5 barrels at a gun show for 10 bucks each and a bolt for 20.
There's a lot of parts out there.
Who's in ??

Cutter,
I am interested but just too involved with the firing problem of the D&E. I would like the opportunity to work with you. I will, however, follow the posts with much interest.

Steve,
I'm looking at this as a secondary build.
Maybe taking around 2 years.
If you have comments or suggestions jump in, I want different ideas.
Good luck with the problem.

And Thanks
Jerry

The aluminum prototype bolt for the Rat Gat is almost finished.
The bolts will be 303 stainless.
Most of you will recognize the hardware.

Here's a good comparison of the Carrier.
1.5 X larger.

Yes Bruski, It's getting a little bigger.
I changed from 5 to 6 barrels, and those bolt bore's are .875

Cutter,
Have you finished the prototype aluminum bolt for this gat? I am curious as to what the front section of the bolt is going to look like along with the rear firing pin area.

The rear of the bolt similar to RG-G design.
But a lot more room to work with.

Cool... I just acquired another dozen rusty .22 barrels, but I'd have to sleeve them up to get to .920. Is that what you did?

No Shred, I took the easy way.
Midway had the .92's on sale in Aug. for 89 bucks.

These are Extractors used on Ruger 10/22 semi-automatic rimfire rifle
also used for a magnum version, and a pistol.
They've been around about 50 years.
Thousands of original or aftermarket parts available.

In case you were wondering, I thought that I would try and print one in plastic then use it as a pattern to cast one out of aluminum.
