Spectre Ballistics Light Practical Carbine - NR Receiver Set

[SpectreBallistics]

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?

You could just make different materials an option. Base model out of 6061 and those who absolutely need it to be 7075 pay for the more expensive material and machine time.

What technical advantages do you see in making it out of 7075 other than the internet says it's better?

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.

Custom chamber fluting service! Lol

All the more reason to go with a .458 build, then. Much lower pressure.

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

Nice.
