Found some "prints" of the 180 but the upper isnt a standard size of tubing and I fugure its all going to be oddball so ive started redrawing it to standard size and to use a Ar15 bolt.

You can weld aluminum, so why not make one from aluminum.

Yes, I was ridiculed on another forum over a year ago because I dared to try welding aluminum with my little 110V mig welder and a tank of argon.

It's not that hard really. It's not easy. But it's not impossible.

I'm doing a tutorial on another forum. Building a 10/22 receiver from scratch.

Have milled thru the welds and as long as you pre-heat with a propane torch you get good solid welds with no porosity.

Not quite finished yet. Still need to do some touch ups in a few spots and belt sand it smooth.

Go ahead and bash away, I've heard it all before.

It will never feed aluminum wire (no problem), it will crack (no cracking) etc. etc. etc.

My mig must have special properties, LOL.

you know if i had a wire welder i would try that.

matter of fact i got some special rods for the old cracker box i could try--just to see if it is possible with the tools i got.

Bash?

I just want to know which wire you are using.

That looks good.

.035 aluminum wire. You can find the small spools on eBay for around $10 and free shipping.

Here is how I mounted it inside my welder. Used a long deck screw to hold it.

Wire speed is on 10 (10 out of 10), otherwise I burn up the tips.

I'm going to try to borrow some CO2 mix and see what kind of results I get.

Be advised, aluminum is affected by gravity, meaning if you are running your puddle the aluminum can get so soft that you end up with a blob heading straight for the floor. I backed it up with another aluminum block to keep it from drooping.
