Textron is getting ready for part 1 of the testing by delivering 30 weapons (15 of the rifles and 15 of the machine guns) and 185,000 rounds of ammunition

And it sounds like they are ready to meet demands for part 2 of testing with 30 Rifles, 28 Automatic Rifles and 680,000 rounds of ammunition.

dextron will not make the cut. too complicated.
The pcp ammo shows some potential but still not a reliable choice for mass adoption. There are still more unknowns than knows.
Having rounds that do not fit in even short action magazines will require medium magnum size magazines that will defeat the original
purpose of the lighter round in the first place.
The bullpups have been there for decades so the fact that have not been massively adopted is because the operations do not like
the magazine under the arm pit. Reloads are not a favorite thing.
The only one I see with potential is the 338 NM from General dynamics that makes so much sense.
IMO a good MBR will have to avoid the extended buffer tube.
Be modular and use a squared carrier that can take any bolt of any bolt face size.
For this a 3 lug design with a 30 degree cam is perfect for this.
In terms of the ammunition a compact 6mm not much lager than the 5.56 will give a very nice 80-90gr round.
The 6.8spc case in 6mm would be perfect for this or just work with a strengthened 6.8 spcIII and be done.
This idea one caliber is going to replace them all is absurd. We will need a compact caliber no matter what.

I mean in the video they standard set up style rifles. Not bulpups or mags under the pit

when is the last time any army anywhere adopted a service cartridge without a shallow shoulder? yes you got that right, never.
If you know why that is then you know the flaws in some of these designs.
Read stoners designs directives in the black rifle book. Also Kalashnikovs. So many things so different yet some so similar.

I looked at the design of internal components and they are way too many with too many moving parts and tight fit.
Normally a tell sign of things to come. Of course they can still make it but the more of these attributes ones sees
that have killed other initiatives, the larger the chances that will not make long term trials.
Once we introduce water, dirt, mud, ice, heat, then all things start to show including the ammo design.
H&K had to abandon the symmetrical ceaseless design when they were faced with the dirt/debris tests just because of the amount
of debris that get packed ahead of the breach. Something classic bullet are more forgiving and they shear off debris
and the operators are also used to just wipe in one stroke and the classic bottle neck simply sheds naturally.
imagine debris stuck between the bullet tip and the sqare neck all that compounded with the tight tolerances of
the two part mechanism of the breach that needs to be tight to support this ceaseless cartridge.
Maybe as we learn more those things have been resolved but initially I would have taken a more simple approach.
IMO there is a need for two calibers one compact and the other one caseless. Also with the 7.62x51 once you introduce
CNC or lead-free 2 or 3 part bullets the ballistics improve drastically for a 130-140gr bullet. the 308 also makes a better
bullet for anti-material purposes and for long range even better than the 6mm, 6.5 or 6.8.
6.8 is splitting heads with the amazing capabilities of the 7mm bore. In fact the 7mm will do everything the 308 does much
better but the one thing the 30 bore is still very good with modern lead free bullets.
This can be demonstrated any time just looking at specialized loads from civilian market.
For a compact caliber the 6mm is hard to beat. The chinese made the right more but still fell a tad short on the casing
and bullet. IMO the 6.8 SPC in 6mm would make an amazing SBR compact round. Just look at the ballistics of the 6mm wasp
in a 58Kpsi case. lead free 80-90gr lead free ammo would make this the best compact service round ever.

just my 2 cents anyway.

Oh cool so a claim but nothing to back it up??

Hard press to believe that this company has released anything detailed about their systems that are not even at the first phase of testing with the army...

Don't get me wrong if there is id love to see these photos... just again hard to believe that they are tossing out their company secrets before anything even gets to the testing grounds
