Cheaper than Maccabee, nice! Will we need any proprietary parts, or can we expect the vast majority of milspec and lightweight bolt carriers, bolt, barrels and handguards to work with it? From what I can remember (and please correct me if I'm wrong), the MV had proprietary parts that didn't allow customers to build it themselves entirely.

Send us an email Tinman304, and anyone else interested to info@albertatacticalrifle.com and we'll send you the little info packet that we've put together.
I didn’t know that they had a larger ports. Hmm. I was going to make a 50 Beowulf or 458 socom.

The weight of the stripped receivers is 19 oz. or 1.2lbs.
We can manually place a 50 Beowulf cartridge through the ejection port. This does not necessarily mean it will eject properly, as clearly there needs to be some clearance and everything is happening much much faster in live fire. Individual modification to the ejection port to accommodate these calibers is possible on your own, through your local gunsmith, or we can have our gunsmiths here modify the port as needed. But they would absolutely be done on a one-by-one basis and there are no current plans for a 'run' of big-bore specific uppers.
I was asking, not stating. But my hope is that ATRS will make the port large enough. Example:
I have a 50 beowulf and I was just saying, I never noticed it larger. but it is.
Cheaper AND lighter than Maccabee's SLR? Yes please. Is there a rough timeframe as to when these will be available? I understand that you're waiting for the FRT but assuming you got that tomorrow, I was curious when I could order these and when I could potentially expect them in my hands.

In measuring our port, it is 50 thou wider than a 'typical' forged upper. We will look into this a little further and discuss. Thanks everyone for bringing forth these suggestions.
Assuming you're using a lightweight bolt carrier (let's say a titanium one, or even a steel lightened one), here's my estimate for a light build based on the receiver weight provided by Shaun, and a 18.6" pencil barrel. They can be EVEN LIGHTER if you go with all titanium parts for stuff like the castle nut, end plate, selector switch, etc.
You can do a 5 lb empty build pretty easily and still have a NR barrel length. The lightness of your build is only limited by how much money you want to throw at it.
My understanding is that they only mention the weight of the carrier itself as 5.6, and then I added extra weight for the bolt assembly. It does mention that it comes fully assembled, but the wording is inexact. I'll change it if I'm wrong, of course. But if it's 5.6 for the whole assembly, that's nuts since that means the carrier itself is only like 100 grams. Also, where'd you get one? I'd love to have that myself since it has pretty good reviews on Youtube and elsewhere.
I just came across Smoke Composites, and they have a very interesting carbon fiber stock that weighs only 4 - 7 oz depending on what length you get and the extra options you decide to put into it. Lighter than the Sabertube but a bit more expensive, although the Sabertube looks fantastic and it's on my wishlist!

If the Modern Sporter comes out soon it could certainly put a big dent in the milspec AR receiver market considering that many people want an NR version of it! For those wanting to stick to SBRs I don't see why regular ARs wouldn't be the best option considering that they're restricted by default.

About 4 hours, the biggest part of that being the time the EDM takes to cut out the mag well.

It appears you live in the same city we are located in, drop by and we can put 1 in your hands.
