You ordered 10 round belts and a drum blocked to 10 rounds? (Right)

Wow, thanks for the updates on the build. One day I hope to have the skill and time to build one as well.

I actually hold a high capacity magazine license so I can order 50 round belts, there are no restriction on drums seeing they are not the actual feeding device. When I build guns like this for my customers I provide 10 round belt/magazine with the weapon. Seeing you can feed a belt into one of these using a starter tab the question comes up whether the mag lock actually makes it a "non detachable magazine". With the drum in place and the loading gate secure you can only load one 10 round belt. I also crush the link before and after the 10 rounds so additional rounds or starter tabs can not be added. I want to cry every time I do it but that's the cost of living in Ca. This particular interpretation of the regulations I'm sure will spur some disagreement. I my self do not necessarily agree with this but I can not get DOJ or any other government agency to give me any guidance on it. Therefore I try to cover all possible interpretations. I guess this is a good reason why people go with grip wraps and deactivate the flash hinder. I just like to keep my guns looking as original as possible.

I am very happy with the progress so far. I am having to take a break for a couple of weeks while I build this welding jig but once that is done I will be back to it.

Finally got the welding jig done. Here it is with the receiver sections mounted on it. Not only does it hold everything straight the top plate will prevent warping and sets overall length

To weld the sections together I will be using the same technique I used on the Bren gun. I will fit the sections tightly then cut them back 45 degrees on the outside. Using the MIG I will then melt the joint and flow the weld to fill the channel. More grinding than with other techniques but it worked real well before.

Seeing that back gap was quite wide I built up the edges so that the joints fit tightly. I shaped the inside to match ensuring the bolt and carrier would slide freely.

Now I can put an angle on the outside and create a channel to weld in. In some areas the angle will be a lot deeper to reach all the way into the receiver

Started welding today. I like to work oposite ends on oposite sides to reduce the ammount of heat that is applied in one area. This along with allowing it to cool between welds will help control warping.

And now I start to work on the front. I will go back and forth over the course of the day till the sides are done. Then I will wait till it cools all the way down and remove the top plate of the jig and weld the top.

yes I welded the ends then reshaped it to close that gap. I squared up the ends at a common angle and cleaned up the inside. That allowed me a close fitting joint on the inside.

So not to bore you with every little weld I did, here is the front with the jig removed. Now I can access the area around the reciprocator and a couple other areas I could not reach from the outside. Now it's on to cleaning up the welds.

I couldn't wait so I started cleaning it up. First I grind, then file, and lastly sand and polish internals. Here I have grinded the top of the weld

Alot of filing and sanding but here is the receiver all together. Now I head to the inside to file out any high points and start fitting the charging handle and bolt.

Here i have the bolt fitted. Its a good thing there was only 2 cuts it would have been a real pain to reach the center of this thing to file out. At this point I am just fitting everything and will come back later and polish the inside.

The charging handle slot is a pain. You can get to the open end easy enough but the closed end you have to get in there by hand a dremel will only go so far.

Looks like I got the length right. I will move on to the bolt conversion next but need to start thinking of a bullet button. I got some ideas so I will start to lay that out too.

Nice work!

You lucked out on that reciever only being a 2 cut.
My buddy did his with a 3 cut and it was a pain in the *** to true the rails in the middle.

on to the bolt. Remeber that part we took out at the begining. Now we are going to fill that in using a mild steel filler piece that we will weld in place.

Here it is cleaned up. I added some more weld to the back of the insert after I read further into the conversion of bolt and carrier. It will make more sence in a few.

We also remove more of the full auto features by cutting out the ramp on the bolt.
