Guess who has 2 thumbs and got a beautiful rpd kit..... This guy!! So if someone wants to actually order a kit and do abuild with me I will start documenting it. It's not a cheap kit anymore its gone up $200 since I ordered mine. Cebterfire systems has them your looking at about $800. But they look brand new when they got cut up numbers matching and comes with a drum. It's a reweld project so have a welder and know how to use it. I hope someone wants to take it on its a sweet little rifle. Oh and by the way the chrome lined original barrel is with the kit intact.

Awesome GAPatriot! Looking forward for the first pictures

I'm only taking the time to document the build if someone will build along, otherwise it just slows me down. Pictures or video of the finished rifle will be posted however

You son of a bitch.

Can you smell the jealousy from all the way out here in Commiefornia?

If you look in the background of the third picture you can see the barrel of the SG43

So was the receiver cut so in theory you couldn't use it? Sorry to seem dense here.

gapatriot · « **Reply #8 on:** November 24, 2013, 09:19:05 AM »

Torch cut, they have banned the import of receivers. So once cut into four pieces its legally scrap. So after its welded back together it becomes a US made receiver. So it counts as a 922r part. But you have to put in full auto denials so that unmodified f/a parts can't be installed. I'm still trying to figure out how I'm going to design my fire control group. There is a proven striker setup but I want hammer fired.

So now that your receiver is US made, what is your plan for your other US made parts to complete your weapon?

Can you make this a select fire weapon and pay for your $200- stamp from the Dept Of Treasury? Or since the receiver was now made in the US (in theory) in 2013 and even if the weapon was made prior to 1986, this weapon can not be made select fire?

Man O' man, the laws are so confusing.

It's pretty cool though even if you only have a semi-auto

gapatriot · « **Reply #10 on:** November 24, 2013, 01:26:38 PM »

In order to make it f/a it would have to be a post sample build. Since it was a registered pre 86. I wish the would lift the ban! Could you imagine all the taxes the .gov would receive

Just rubbing it in. I got to see the build and finger fuck it as well. Needless to say, its a fucking beauty of a build. He's done a good job on it so far. I can't wait to see it all put together.

When metal is torch cut it melts the metal into slag making the parts not line up or shorter than they should be. Are you adding metal inserts to get the right length again? Also when you weld it you have weld on the inside of the receiver how are you removing this?

I've been talking to GAP all though this build.. He's filling with his mig by lapping welds into the void all while backing it with copper plate to act as a poor man's carbon block.

I've asked the same question about removing excess metal from the inside of the receiver and he maintains that it will be reachable via dremel tool.

Hmmm I feel like it won't be nearly as strong. But if that works then hell I want to give it a shot, its to bad they can't make clean cuts with a band saw but that wouldn't be considered demilling.

Just an update she's coming along....

thatGuy · « **Reply #16 on:** February 07, 2014, 10:04:44 PM »

This is the third fucking time I've tied to reply to you Gunner.. I hate my God damn phone!

LA100 mig wire has a tensile strength of 689MPa or something like that.. Its low alloy 100k psi

Structual steel is in the mid 200MPa just as an example.

Should be stonger then the base metal.

Actually the receiver is "soft steel" the weld is actually harder that the base metal. Also the are tons of rewelds that have plenty of rounds thru them with no issues. Hell I have a sh-43 reweld that is rocking a repaired de mill barrel and other than some not fixed yet due to New kit head space issues has rounds down range (7.62x54R). It all comes down to how much you trust your welds.

Damb tg I was writing a reply when you were

came across a Mac 11 weld together receiver today... Hint hint wink wink

Show me this mac 11?!?

COBRAY MADE buck and a quarter........ Sold already should have texted you about It

gapatriot · « **Reply #22 on:** February 07, 2014, 10:58:53 PM »

It's a mac 11 not 10 so its the smaller one and it ain't a uzi... But I will keep you posted there have been a few macs up lately. By the by would you be interested in a slightly over priced swedish k?

Gunner · « **Reply #23 on:** February 08, 2014, 12:51:20 AM »

Haha don't you love technology? If that's the case then hell I'm going to jump on this. I have passed so many up just because the receivers are hard to get. I have been welding for about 10 years and welded up a few builds so I'm not to worried about that. I just never thought it would be so simple. How do you prevent warpage? Single passes?

Oh it warps bad!! Ds arms has a complete receiver at a reasonable price. Check out weapons guild forum its a wealth of knowledge. I haven't even got to the hard part yet which is the fcg. Just remember before you start welding to cut the carrier so is not f/a and as your welding it up to put in f/a denials so a f/a carrier can't be installed. Most guys are building these with as striker fired I have an idea to set it up as hammer fired but don't know if it will work or not.
