Is there a need for more Cdn made AR parts?

The caliber is dictated by the upper, so to the best of my knowledge, no caliber designation is required, but I will inquire of the CFC to be certain.

I photoshopped the picture you posted. Is something like this possible?
THAT is awesome!!
The fire oontrol marking will be option #9 for sure
Will look into the artwork for potential problems and advise.

Now that I really like! If this lower is an option I may have to put my order in.

Making them 1 at a time rather than mass producing ensures , at least here, 100% quality control. An error in machining will be caught in the QC process, before anything is sent out for anodizing it will be tested on an upper for fit and function.
Billet aluminums quality is vastly superior to castings or forgings, air pockets or inclusions in billet material is virtually unheard of. The reason I am using 7075-T651 is that it is considerably more structural than the cheaper alloys commonly used.

Along the lines of this, will you be checking that different manufacturer's uppers fit properly? I had to do some filing to get my uppers to fit my Dlask.
I currently have a Bushmaster, DPMS and Colt M4 upper on hand to make sure the lowers fit.
I know that some of the older Colt and Olympics were not the same spec as current production uppers are. If I can get my hands on other brands to check as well that would be great. I do want to make every effort to be sure that NO fitting or dickin around is required to make them fit together properly.
Any NDA protocol to check for internal material defects? (Mag Particle, X-Ray, Ultrasonic?) I don't know enough about the mechanical function of the AR lower. What would the effect of a critical failure (crack during firing or cycling) as a result of interior flaw in the billet?
What timetable would you be on to begin offering for sale?

Not being a metalurgist I am not certain about testing for internal defects, my understanding is that billet material is about as pure and guranteed free of inclusion as possible. To X-Ray or Magnaflux each piece would be expensive and honestly I think needless. I know of no-one who performs this on rifle barrels and that would be of much greater concern in my mind.
The lower is not subject to much stress from use. I have a Ferret 50BMG that is held onto a cheap casting lower by 2 1/4" pins and has seen a fair bit of use, with no issues. I would think putting a 50BMG on an AR lower would quickly determine whether the lower is of sound strength and design.
To have a crack occur would be seen and a smart person would cease using it. The chances of both pin ears on the fron sheering off at the same time would be about as high as winning the lottery repeatedly.
Milspec is to use 6061 aluminum which is much softer and has no where near the tensile strength of 7075. I would think that if this was a concern someone in the AR building business would have brought the defect to the attention of the masses sometime over the last nearly 40 years that these guns have been in use.
Understand I am not an AR15 oracle, so if anyone has info on this, now would be a great time to bring it up.
Timetable is , material will be here late next week so production will start forthwith. With luck we should be shipping product in 6 to 8 weeks
Well good luck, I look forwards to buying one when they are ready.
To the metallurgy question, again I am not an AR specialist, I am actually quite ignorant on the specifics of the gas-block design. If no-one does it with cast 6061-T6, then it obviously is not necessary.
What sort of finish? Anodized Black?
guess I should I start collecting uppers, stocks and furniture.

Question: Why have a City and Province on the Lower?
Alberta is already in Your name - The Manufacturer
The maple leaf is great w/ the canada below.
Having Alberta on it twice seems a bit much. (just a thought)
Anyone remember those pirate lowers. safe = Parley Fire = Plunder
