"The reason 6.8 is so great is because it's not as optimized as the 6.5 Grendel."

"What about the 7.62x39?"

"REEEEEEEEEEEEEEEEEEEEEEEEEEEE"

I woke up one day and decided "why not design an entirely new rifle from scratch, and live blog it?" So here we are.

About ten minutes in and we've got the beginnings of a receiver extrusion made from 7075 T6 aluminum:
 

 
Currently I think the rifle will be in 5.56mm. It will not use STANAG magazines. @Ulric plz halp design new mag?

Just copy paste this - "https://www.youtube.com/watch?v=pV1NDsggBsk" (without " ") and forum wil automatically embed it.

NATO Science and Technology Organization Technical Reports

Sorta like a NATO DTIC
Found this the other day while googling around for soldier-load related information (IIRC, I was trying to find the mean bodyweight of infantrymen infantrypersons)

UK Award Heckler & Koch $95 million Contract For SA80 Rifle Upgrade

 
 
 
To put that into perspective, the retail price of a 15.7" Colt Canada Gen3 IUR is 2379.95CAD or £1385.10

"AN ARMY OUTGUNNED: Physics Demands A New Basic Combat Weapon" by Joseph P. Avery, Ph.D

Two observations: 1)Title mentions a new "BCW", but not why. 2)Yes he has a PhD, but it's not a STEM degree
 
 
Homeslice needs to "stay in his lane"

I've skimmed through the first 4 paragraphs so far, and each is built a a derp-diamond:

(bolding courtesy of your CDNcommissar, the helpful politest commissar)

The bulk of the first paragraph:
lol no

Second paragraph - MP.44 and AK-47 derp:
lolwut
Jesus, no
#triggered

Third paragraph - Blathers on about Marshall's nonsense, before mentioning that Marshall was spewing nonsense
But wait! There's more, Peak Derp (of this paragraph) is achieved in the last sentence:
u wot m8?
"The Cult of the Rifleman"

Forth paragraph's Peak Derp, again in the last sentence:

FIND (from FIND, FIX, FIGHT, FINISH) (the more contemporary version F2T2EA is FIND, FIX, TRACK, TARGET, ENGAGE, ASSESS...IMHO a worse acronym, but I digress) is still extremely difficult. The enemy still gets a vote. 
He is equivocating long LOS with higher visibility.
A handful of counterexamples to his point that today's combat environment is different: the steppes of the Eastern Front had quite long LOS, the desert combat of Desert Storm had quite long LOS etc etc
It's not really any different. Conflict occurs in environments where humans are, just as it always has. 
 
This is a important aspect of the disadvantages with 5.56 replacements, they neglect the difficulties with FIND (while and/or assuming perfect conditions for a more powerful cartridge)
His reasoning: combat environment is different, longer LOS -> MOAR VISIBLE -> 223 POODLE VARMINT SHOOTER LACKS RANGE

Fifth paragraph: MUH THURDY CAL WOOD AND STEEL(?)
ugh
