Current RM277 is a 19" barrel for 3000fps, so not much of a stretch to go from 16" to 19" for the LMG.

Current SIG NGSW-AR has a 16" barrel (not 19").

Original GD NGSW-AR had a 22" barrel (not 19").

Especially if the shorter Brevis suppressor was used vs the longer sig suppressor to offset some of the length increase.

First you want SIG to convert their guns to fire a competitor's ammo, thereby reducing SIG's profits.

Now you want SIG to switch to a competitor's suppressor, which would further reduce SIG's profits.

These are completely unrealistic proposals.  There is no rational reason for SIG to willingly do either.

Do you think the Army made the right call going with SIG, and that the accuracy issues would likely persist with the TV design?

The SIG round & offer were the "least risk" option, so it makes sense, but I would bet that this was not the way the US Army wanted the NGSW to go.

We should probably stop to write that there is "accuracy issues with the TV design".

What "we know" is that there was probably a mismatch between the XM1186 bullet, the 6.8 mm TVCM cartridge, and the RM-277 rifle. Fire the 6.8 mm TVCM cartridge loaded with a 135 gr SMK bullet in a bolt-action rifle, and you won't see "accuracy problems".

I just hope that TV will launch the 6.8 mm on the commercial market, allowing them to refine the design until it's OK for military application. With the exception of "spitzer" bullets, it seems that every small-arms evolution was first tested extensively in the civilian domain, before being adopted by military forces.

That seems to be the plan.  relaxed

Interesting to see Mr. Sal Fanelli in the video.

That was the plan back when they thought they had a good shot at winning the competition. Otherwise, TV is an ammo company rather than a gun company. And trying to sell a fairly mechanically complex bullpup design that lost its trial, is going to be a bother for them I think. At best a few ~$10k rifles are made for whomever is crazy enough to pay that much, and the gun vanishes into the air afterwards.

I wonder whether other nations will adopt it.

That still is the plan.  That was posted by TV about a week ago. 

The only apparent difference is that the rifle's name was changed from Genesis to Amicus.

TV bought LoneStar.  Which makes TV a gun company as well as an ammo company.

Smokeless powder was the product of French army lab, it wasn't tested by civilians first, it was basically the NGSW of it's day except actually good

It's not actually possible that TV's cases don't work. We've got more TV ammo out in the wild and being shot than we have of sig ammo.

It really is ok to just straight out say the army made an extremely stupid call here.

The world won't end, that's what happened, and all we can hope for now is that whoever in the army is afraid of muh plastic ammo gets fired or reassigned so the army can correct it's course in time.

I don't like saying any of this but this is the truth of the situation as it currently stands
