Hello all, this is my first post here, so I hope everything is alright.
I'm getting into machining, and I figured I could do a fair bit of learning by working with firearms. As far as my experience on guns so far, it's limited to the AR. What I wanted to know was what models of lowers, receivers, or the part referred to legally as the firearm, can be machined by a beginner? I know the ar and ak are pretty simple, but for example an m14 must be heat treated after machining. That's the kind of thing I can't do. What models would I be able to make? I live in CA, so come July 1st, I can't do this anymore without paying ridiculous taxes. Just trying to do what I can while I can. On a side note, I don't know too much about realistically 3d printing receivers, but I have access to a printer if that's a possibility. Also, I'm only 18, so handguns are out of the question. Thanks in advance

Welcome to Weaponeer.

A tube gun like a sten should get you hooked.

i wouldnt think much of 3D printing for making guns at this point, the end result is always fairly poor and in the case of AR-15s a lot of injection moulded polymer (much stronger) lowers still snap off at the rear tower for the buffer tube if not reinforced

youre better off with a milling machine of some sort, the grizzly G0704 is fairly inexpensive and gets the job done but if youre building from 80% the AR-15 can be done with a $100 drill press, and the AK receivers would need a shop press to bend and rivet the flat, and a spot welder and be heat treated afterwards

the reason receivers like the M14s have to be heat treated is because this is where the locking lugs are, they are machined into the rifle and require the strength to operate safely, an AR-15 for example has the locking lugs machined into a hardened extension threaded onto the barrel which allows the upper of the AR-15 to use structurally weaker materials safely

if heat treating is something you are uncomfortable doing, then i suggest you get a $50-$100 used kiln off craigslist and learn how to do it, its not that hard, nor is it that expensive and once you have the tool and knowledge to do so, it'll open you up to being able to do a lot more

Knock out as many 80% AR lowers as you can afford before your deadline is the simple solution.  Study the law carefully; under Federal law, you may BUILD your own pistol, just not buy one from a dealer before you turn 21.  How California might view that I don't know.

If you have a hard time w/ aluminum lowers, EP Armory has plastic ones for $30 you can practice on - they are inherently weak @ the buffer tower, but you can reinforce that (for a price) w/ a non-thumbhole stock.

As Justin will tell you, I'm an advocate of the AR platform b/c it is so flexible.  The 1st guns I've made have been AR based b/c of the unique relationship btwn the upper and lower and the ubiquity of AR parts on the market.

3-D printing an AR @ home is a tedious exercise; I think War Fairy's Charon is likely the strongest, as it has the reinforcing thumbhole stock - but it will take you quite some time to print that stock.  Hera's compliant non-thumbhole stock is relatively expensive, but will save you quite some time if you go that route.

If you weld, you can inexpensively assemble steel AR lowers from the Flat Spot - heavy, but nigh indestructible.

You can always 3d print a receiver and then do a lost casting technique to create it out of aluminum. Search lost PLA casting and you will see what I mean.There are a lot a DIY forges on youtube if that is something you wanted to get into. Besides, after the deadline you will always have a fun new hobby. With that said I echo the above and would not trust a 3d printed receiver that is not adequately reinforced.

ive thought about 3D printing for making moulds, problem with that is though that a cast part still needs some machining operations and if you have the ability to machine and knew how to use it you wouldnt need to cast

im hoping to buy land and start building a workshop myself soon after, my plan is to buy an old bridgeport to refurbish and convert to CNC as my main tool
