What I find interesting is contractors are tasked with developing a new rifle and new auto rifle and a new cartridge utilizing Government provided 6.8 millimeter projectiles so they won’t be limited to a 6.8 SPC case. I would really like to see what the provided 6.8 mm bullets look like.
Attachment 3 has the ammo specs but is not attached to the document you have to request the data.
This sounds like the best solution to an optimized firearm for general issue as well as the squad automatic rifle.
Military gives a set of designs and outcomes for their bullet (the capability of penetrating Russian Manufactured body armor between 0-400 yards), the companies that take on the challenge can start with cartridge design for meeting the challenge out of a barrel length. The company can be in control of how long the cartridge needs to be to feed reliably at both semi-auto and cyclic full auto. The company can then develop the magazine and metal link that the cartridge feeds from. Finally the company can create an optimized rifle/carbine from the capable feed mechanism.
So they have a bullet and they want someone to design a gun and a round around it… While I admire the clean-sheet of paper freedom that entails, it seems that if you are going to replace 762 and 556 ammo AND get a new gun all at the same time- that seems a little ambitious.
