Aluminum AR180B lower. *Update DONE!*

Interesting project, but be carefull.

If it turns out to be restricted, it's restricted. I'll just have a useless restricted reciever then. I think I'm going to revamp the design. Maintain the use of AR15 grips but change the trigger guard and magwell area so it doesn't look so AR15-ish.

I have seen the bolt together one, I have the plans here. This it was got me started. I figured for how much more trouble it is, might as well try to make it froma solid billet. Of course that could change.
 
Neat Project.

The CFC is pretty clear that the AR180B and variants is non-restricted.

I think ArmedSask should get a Custom Rail foregrip project out first :) Im sure that there would be lotsa buyers ;)
 
As I see it, the only shortcoming of the AR180b rifles is the polymer lower reciever. It would be great if a metal lower was available for a reasonable price. I would be interested in that kind of an upgrade (depending on cost). After you have a proven/problem free lower, maybe do a cost calculation on a short production run for fellow 180b afficianados (sp?). :)
 
Is the lower not the registered part? HOw would this work for you to make your own? Would you make your own ser. no. and then have your stripped plastic lower still registered to you but not used? I could see it working for your own personal use but how many hoops do you have to jump through to sell these? Just curious as I might want one of these later on. I got dibs on ser. no. 000069.
 
Crazy idea, but if you've got CAD plans (or really, any plans from a mainstream 3d package), what about www.emachineshop.com? These guys have software that will actually give you a quote, based on the complexity of your geometry, desired materials, # of units you want to buy, etc.

You could have AR-180B lowers done up in anything from clear lexan to sterling silver, to of course aluminum.

I love living in teh future;-)

Yes, the lower is the registered part. I would be making a new registered firearm. Whne completely the firearm must be verified within 30 days, it is then assigned a unique serial number, or your own if you put one on it. It will also be entered in the FRT with a unique number.

Making them for sale is a whole other can of potatoes. That would require a manufacturers liscence (unless I get some one like Dlask to make them, who already has a manufacturers liscence). If I remember correctly it is perfectly legal to make your own gun and I think you are allowed to sell one per year. Selling more than one a year requires a manufacturers liscence. I could be wrong on the selling thing, that might be something from the US.

I might piss around with that emachine shop just to see what they would charge but they are not an option as we are dealing with a firearm here.

I just tried to get a quote from eMachineshop just to do the magwell out of a billet of aluminium. for some reason they said the 6061 isnt compatible with the wire EDM, lol !!! but the quote was $160 USD per magwell. VERY expensive. i will look around at shops around Minneapolis and ST. Paul for real quotes.

Josh, is there a reason the mag well couldn't be made simpler? Just a box with one slot for the mag catch hole bump.

You can predrill the corners and use long endmills but you will have to flip the part and mill from the top and bottom. unless you make the magwell a 3 sided box and Tig weld it onto the receiver after milling.
You want the DVD on how to make the receiver on your home mill?

Another member sudgested a great cost savings, make the reciever and then send it to Dlask to have the magwell cut. Would probably be the easiest way to do it.

How much for the DVD?
 
I just love the idea of the pinned/bolted/screwed together design. I can certainly picture a LARGE number of fairly generic parts (think lego blocks) being put together into a firearm receiver, and then the RCMP forensics folks scratching their heads trying to figure out which individual part they will designate as the "receiver", once you have one of these things properly registered, FRT'd, and designated non-restricted, the fun begin rearranging the above-mentioned lego blocks ... as whatever you come up with could not be classed as a "variant" of anything because whatever individual block is designated as the "receiver" remains unaltered ..... So many ways to screw with them, so little time ... lol
 
EDM discharge is a nice clean way to do the magwell - but a milling machine will do nicely - even a decent drill press!

You read my mind! If you look at that scratch built AR15 page, if you did something like that with bolted together pieces, it would be a good time! A bunch of aluminum parts aren't a reciever by any stretch of the imagination. You receive a bag of aluminum blocks, thread some holes, maybe have to drill some too, bolt it together and your set. Instant reciever.

did you have to notify anyone about your intentions to build a receiver (other than asking if the Forensics officer if it would be considered a restricted or not), or can you just build a receiver, book time with a verifier to get it verified, and then go home? What, please is the precise chain of events that must happen when building a receiver from scratch, so as not to end up in jail?:)

Good question, I should look into that.

In case any one is wondering, the billet lower has been placed on the back burner for now. A better route is being taken to allow for ease of manufacture. Stayed tuned.
 
Mould?

How about a latex moulding with a secondary wax object and lost wax process?
You can get astounding precision in a ceramic shell casting and you still have a repeat capability.
A good lost wax casting leave you with a part that only needs a few regular machining passes to be ready.

"...higher..." Higher than who? Think $60 or more per hour plus materials. Add the cost of any special tooling too. You're likely looking at $1,000 or more.
"...chief forensics officer..." He doesn't make the rules.

I'm glad you could contribute with your fantastic wisdom, as usual.

I should note that it should be Chief Firearms Forensics Officer. He is the guy who decides the classification of firearms and the rules are fairly specific. This is clearly a variant of the AR180B.

How true, the eternal and misguided wet blanket of the internet that is sunray :p

But all kidding aside, really neat project Armedsask, about time somebody did it. :) In all honesty, Dlask is probably the best bet, and Joseph knows his stuff.
 
You could try contacting Rotary Air Force in Kindersley, they might be able to do the machining for you on a solid aluminum receiver or cut and bend material on a sheet metal receiver. Last I heard they had some really nice equipment there.
