My first post on AR15.com. Mods, if I'm in the wrong section I apologise, please move it to the right one!
I asked a similar question on another forum, but the forum didn't have to do with firearms and I think I may have made a mistake mentioning it was to do with firearms because they started saying some stupid stuff, probably in an idiotic attempt to "troll the uneducated reactionary redneck" that they probably assumed I was when I said I was designing a gun. So I'm now here to ask a similar question, hopefully as fellow firearms owners and enthusiasts I'll get some good answers.
So about myself and some background: I'm an engineering student and IPSC pistol shooter from Australia. If any of you guys know anything about Australian firearms laws, well, I can tell you, they're not pretty. All semi-auto longarms and pump-shotguns are restricted to farmers who show a "genuine need" for them (for shotguns and .22s) or people who make a majority of their living off culling feral animals (for centrefire). Handguns under .38cal, with barrels over 120mm (about 4 and half inches) and under 10 round magazines are available to shooters who are members of a club and shoot regularly (like me). However, manual action longarms (except the aforementioned pump-action shotguns) are relatively easy to get.
Now, the pump-action ban only extends to shotguns (probably because back in '96 when the ban happened, none of the anti-gunners knew pump-action rifles existed but everyone knew pump-action shotguns did), so realising this, many shooters use pump-action rifles, pretty much exclusively the Remington 7600 (in 30-06 and derivatives, and .308 and derivatives) and 7615 (.223 Remington/5.56x45mm, doesn't matter it's in 5.56 though as surplus doesn't exist on the Australian market). Being a bit of an entrepreneur, I've been thinking I could design my own pump-action rifle, better than the 7600 range of rifles, not to mention cheaper (the only major importer of firearms and ammo into Australia price gouges everything, for example a Remington 7615 will cost you guy in the US about $700, if that, here they start at $1500 and go much further up)
I'm current at the design phase. So far I've got most of the bolt done, along with the barrel extension, I also have a few sketches as to where everything will be and such. Thinking a little bit ahead I've been running into a few issues, many revolve around legal. Similar to what I think you have in the US, to make a firearm to have to be licence (well, in your case, licensed to make guns for sale), and, similar to what I think you have in the US, you can't just ask another company to make the registered part (the receiver), because then they would be manufacturing it without a licence and all these other silly legal headaches. This pretty much means I wouldn't be able to get someone else to make prototype or the finished product for me, unless they also wished to jump through the legal hoops, something they won't do for a small prototype run without a significant amount of money up front. I could in theory find another firearms manufacturer to do it for me but Australia is rather desolate for firearms manufacturers. We have Thales/ADI, but they only do government work making F88 Steyrs and Minimis, then there was some company in Queensland making modern Lee Enfield, but it seems they went under after it was found out they didn't actually make their guns Australia, rather it was in Vietnam they made them. Finally, there is a company in Melbourne making AR15s an M4 clones for the tiny group of shooters here who can own them (feral animal cullers and for the movie industry), they charge $8500 for them (that is not a typo) and have only sold about 100. These guys would be my best bet if I were too find someone else to make them but they're in another state and they may just flat out turn me down for my proposal.
Now, as for the design, I've taken many ideas form the AR15. Many of the features found in the AR15 are either still revolutionary or are now found in many modern rifles. So in my design I've included a number of things: Spilt upper and lower, aluminium receiver, 7 lug AR15 style rotating bolt. I've even decided to use AR15 lower smalls parts, simply because they're easily available, cheap and it's much easier than making my own as they would be a pain in the ass to machine.
Anyway, when I started asking some questions about CNC milling I started getting some rather interesting comments. I'm pretty sure half of them were trolls but I thought it would be best to ask somewhere relatively troll free to clarify a few points
-Firstly. Would I really be much better off on a manual mill doing this instead of getting a hold of a CNC mill? Most of the comments seemed to be people saying that because my milling experience on both is rather limited (I've only done some introduction stuff as part of uni, nothing too complex) I should just learn manual milling and do it all manually and that no one should go straight to CNC without becoming a pro at manual. In my (possibly incorrect) opinion I would think CNC is a better option. You go from CAD to CAM, CAM does all the pathing giving you your G-code, you enter it into the machine, you double check it to make sure it was entered right, you do a slow dry run to make sure you're not going to crash and ruin your very expensive mill, then you can load up your material, zero it and starting getting parts out pretty quickly. I don't see that as being particularly difficult as CAM does all the calculations for you, on the other hand, manual milling is considerably more difficult. You actually have to have considerable experience and training if you want to pump out parts at any decent pace, and then it's still rather slow. You'd probably also waste a lot of material due to errors. So if anyone here is a hobbiest with a CNC mill who didn't have much milling experience when they started, please tell me your experiences, was it hard to do, hard to learn, etc. Especially if you've made AR15 receivers
-Secondly. Are there any people here who are manual machinists who think they could make an AR15 bolt head (or something similar) on a 3 axis manual mill? The more I think about it the more I think it would be incredibly difficult. Even with a 4-axis manual mill (do they even exist?) it would be tedious
-Thirdly. Does anyone know if you can lease CNC mills for short periods of time? Like a month or two? The consensus I got was the minimum lease time will be 12 months, if not 18 or 24 months. But I could see there being a massive market (which someone must have filled) for short lease CNC equipment. Pretty much for shops who occasionally get projects requiring CNC so instead of having a CNC mill gathering dust for 95% of the year they just bring one in for the time they will actually use it. Though it did occur to me today I could potentially buy a second hand CNC mill, then sell it after I've finished it for nearly the same price I bought it, but that would require me to convince someone with ~$50k to spare to loan that to me (it would be a secure loan though if I don't crash it, pretty easy to repossess).
Cheer to anyone who bothers to read my rather long post cover to cover, I didn't intend to write that much but as I wrote it seemed important to explain the backstory a little bit.
Any help would be wonderful
