Extra uppers will be available.
No. The AR-15 bolt carrier is obviously not set up to have a bolt handle attached to it, so you'd need to at least replace the carrier. Everything else seems like it would be interchangeable? Didn't say anything about the safety selector and stuff, but it would be kind of illogical to change that business up, considering the purpose of the receiver.
Yup,this has me eyeing carbon fiber barrels and handguards just to see how damn light I can make it.
Spectre,is the ejection port capable of handling big rounds like .450 bushmaster?

Just wondering ...a straight bolt action ...like the sig ...and I believe the merkel??....any thoughts about that
Carbon fiber barrels aren't the lightest barrels on the market. They are however significantly lighter than a steel barrel of the same contour. They are designed to give you the benefit of a heavy profile steel barrel but with less weight.
Spectre assembled the rifle with a pencil barrel to achieve the posted weight. Most CF barrels are going to weigh MORE than the pencil profile barrel. The only CF barrel that will weigh about the same as a regular old pencil barrel is the BSF 18.6" Fluted barrel. The non fluted BSF is going to weigh more than a pencil barrel and barrels from Proof Research or Christensen Arms are going to weigh a bit more again.
If your main objective is weight savings you won't achieve that by buying a CF barrel over a regular steel pencil barrel. If you want to focus on weight savings the best place to start will be with a carbon fiber handguard or one like the V Seven Hyper-Light which is made from an aluminum and magnesium alloy blend and weighs in at a mere 5.4 oz. including barrel nut for a 15" handguard.

What technical advantages do you see in making it out of 7075 other than the internet says it's better?
6061 is more than capable of being strong enough. With proper anodizing denting is not an issue. 7075 doubles the cost of raw materials and takes about 10% longer to machine, and is more expensive to finish. This ads a lot of costs to the final product, something which is an issue.
Anodizing is only as strong as the base material. Put a sheet of glass of equal hardness and thickness on top of a mattress, and on top of a flat concrete floor. Jump on both. You can guess what happens.
Are you saying there's no functional reason that the higher end manufacturers are making their sets out of 7075?
I could get into tensile/yield strengths and all that business, but...

There is a difference between 6061 and 7075, obviously. We are not making the claim that they are the same. 7075 has it's place, and so does 6061. For this rifle, there is no functional need for 7075. Using it only enhances the cost. Is 7075 needed for other rifle designs? Perhaps, but 7075 is just not needed for this gun.

How about you get the product to market in 6061, and once it's on the street, you do a special run of 7075 receiver sets for those who sign up for them?
Just an idea - recognizing that it will need a new set of files for the CNC system for speeds and feeds. Obviously this would be a 'special order' with the extra machine time and extra materiel costs resulting in a slightly increased cost to those who feel they need the 7075 for some reason?

Keep it simple.
Get it FaRTed.
Get it on the market.
Then, if convenient, offer extras - 7075, colour options, .308 scaled, etc.
Something to keep in mind, though, with respect to different caliber offerings - an AR pattern barrel extension, bolt and carrier do not have primary extraction. If users load them hot, there are going to be complaints of hard extraction.

Fair enough.
I also had it in my head that this was an AR-15 receiver set. Which it is, and it really isn't. The major difference being that it's not a semi-automatic action, i.e. the bolt will be moving a hell of a low slower, and in theory should produce a lot less wear on the receiver. So you're probably right, in this case 7075 might be more of a luxury than a necessity.

We're going to have the prototype at the Edmonton Gun Show this weekend.
Nice.
