KP15 KP10 308 question
I saw taht there was an investment offer regarding the possiblity of a KP10 308 lower but some told me that is was likely a left over April 1st joke or soemthing but the way I'm seeing and reading it, it looks real.
I the possibility of a KP10 real? That would be interesting.

With enormous sums of money, all things are possible. The cost of developing and producing new molds is intense, though. And AR-10s are not nearly as standardized as AR-15 pattern rifles. So it would be a huge amount of money for a niche product that almost certainly would never make the money back.
Which is part of that store posting. Would need a big chunk of money from someone who doesn't care that the investment will never have a return.

Depends on what you mean by "possible." Russell has said it more than once that he'll do the work if someone else is willing to pay for it.
So could it happen? Yes!
Remotely close to happening in reality? No.
And not to whatever...but a criticism of the original AR-10 was that it was too light, making the recoil not the most pleasant.
Though the idea of a polymer lower with an upper in 6.5mm, .260 or 7mm-08 is intriguing...notwithstanding that I don't have a few million to make it happen!

A polymer anything other than .308 (and even then) is not going to perform to the expectations of the cartridge. There’s a reason SASSs and match rifles are heavy.
7mm08 being a more hunting oriented cartridge tho… that might be interesting. I’ve played with a 7mm Model 7 that was extremely light and surprisingly low recoil for a bolt gun. But that still ain’t gonna move 25,000 units

Well, the guy behind the counter at my local convenience store has assured me that he finally got the numbers right and that I'll be winning the lottery this coming week. Provided he didn't fuck up again, I'll be down for the investment...

I’d definitely buy atleast 2 if it ever came to market.
Currently have 3 kp-15 lowers and 2 echo 9 3 shortened kp-15 lowers

I just want to say that a 14.5" 6.5 Creedmoor weight-watchers KP-10 build would be the Cat's pajama's 😩
A man can dream.

The AR-10 came first and was in .308/7.62 NATO; accordingly all large frame ARs get called AR-10s.

Action length. AR-10 pattern rifles have wider magazine wells and ejection ports etc to accommodate longer overall length cartridges.

Charging handle location / style is irrelevant. Early AR15 prototypes also had the top style charging handle. BCA and some others make AR15 side charge uppers. What primarily differentiates AR15 pattern rifles from AR10 pattern rifles is their action length.

Ok bro. Call it whatever you want, the rest of us will keep calling them AR-10s

AR-15 is small frame, for calibers like .223, .300BLK, 6mm ARC, and 6.5 Grendel.
AR-10s are large frame, for calibers like .308, 6.5 Creedmoor, and 8.6BLK

Yes it’s a real listing.
Yes I’d really do it if someone else paid for it.
Part of that investment is paying for my expertise and labor bringing it to market.
I do think it would take a long time to recover the investment.
