SIG Sauer Won Next Gen Army Contract

[Ringel05]

SIG Sauer has won the contract to provide both the NGSW-Rifle and NGSW-Automatic Rifle to replace the M4/M41A carbine and the M242 Squad Automatic Weapon.
It is chambered in 6.8x51 (the .277 Fury) supposedly to be effective against the Russian Army's (apparently non-existent) body armor......

WASHINGTON – The U.S. Army announced today the award of a 10-year firm-fixed-price follow-on production contract to Sig Sauer for the manufacture and delivery of two Next Generation Squad Weapon variations (the XM5 Rifle and the XM250 Automatic Rifle) and the 6.8 Common Cartridge Family of Ammunition.


This award was made following a rigorous 27-month prototyping and evaluation effort that included numerous technical tests and Soldier touch points of three competing prototype systems. The value of the initial delivery order on the contract is $20.4 million for weapons and ammunition that will undergo testing. The contract includes accessories, spares and contractor support. It also provides the other Department of Defense services and, potentially, Foreign Military Sales countries the opportunity to purchase the NGSW weapons.


The XM5 Rifle will replace the M4/M4A1 carbine within the close combat force, and the XM250 Automatic Rifle is the planned replacement for the M249 Squad Automatic Weapon Both weapons provide significant capability improvements in accuracy, range and overall lethality. They are lightweight, fire more lethal ammunition, mitigate recoil, provide improved barrel performance, and include integrated muzzle sound and flash reduction.

I have an early P226 that is an incredible weapon.

As far as new long rifle goes I have no opinion

But there was nothing wrong with the 1911 .45

For short distances yes but these are good for short and longer range with a powerful, flat trajectory that beats out the current 5.56 NATO round in distance and punch.

Nothing wrong with what they had.

NATO 5.56 cross compatibility out the window? In that case we should have stuck with the 7.62x63mm (.30-06). The 5.56 is plenty powerful—enough to gut both man and beast at respectable ranges. Twas the delivery system that needed improvement—getting rid of buffer tube and spring in the stock, because we were one butt stroke to the head away from an inoperable weapon. Personally, the .300 blackout and .338 spectre are more than adequate for specialized applications across their various slow and speedy loads. Troops specialized enough to worry about Russian or Chinese body armor at this point in time will not be aiming center mass anyway.

Basically they're switching over to an AR10 platform and for some strange reason they didn't ask any of us what we think.
I have no problem with the 5.56 and really not sure why they decided to make this change over except that the weapon system itself is a little lighter and packs more punch at a distance.

Love my SIG AR!!!!
It's never jammed or failed to feed.

My favorite two "heavy hitters" are my home builds, one in 5.56 and the other in 7.62x39. Unfortunately SIGs are out of my price range.

The 5.56:

That 47 is Sweet!!

With that setup, bench rest you can easily hit targets at 300 yards. Not bad for a cartridge basically designed for an effective range of up to only around 150 yards. Granted you're gonna have a heck of a bullet drop at 300 yards and you're losing a lot of velocity but it's kinda fun seeing how far out you can hit the target. The biggest issue are the mags designed for it, typically they need some slight modifications to feed correctly.

This "new" .277 Fury round SIG developed was because that is what the Army specs demanded for the new SAW. The SIG .277 is a 3 part cartridge, the bullet, a brass body with a steel head. Why? Because the the round is 140 grain traveling at 3000 FPS out of a 16" barrel........... That's more that 80,000 PSI in the chamber. By making the cartridge this way it makes the cartridge lighter (less steel wall thickness needed than brass where it's needed) and able to withstand the generated PSI out of their rifle which weighs in at 6.2 pounds.......... That's pretty impressive.

Wonder how they join the steel to the brass, and i wonder why not just use 270 ammo?

Apparently they did what the Army wanted and you can't get that with a 270 out of an 16" barrel. A 22" to 24" barrel is the ideal length for the 270, it loses a lot of velocity out of a 16" barrel.

 

[Ringel05]

Remember this is the replacement for the the M4 and SAW not the standard Infantry rifle.

 

[para bellum]

It's closer to a 7mm-08 than a .270, it still uses a short action.

80,000 PSI is crazy high chamber pressure. 7mm-08 is 61,000 max, which is up there with belted magnums like the 7mm Mag. I wonder how the .277 Fury will hold up. Hope they put a quick-change barrel on that SAW.

Seems like a steel case that's just brass plated would be simpler to manufacture. The barrel will go long before the chamber on a round this hot.

It's belted mag performance in an intermediate cartridge, which is pretty impressive but there's always a trade-off.

I've always like Sig's ergonomics. I've had a few Sig pistols over the years. 220's,226's,230's. EDC's today are Kimber UC2 or Beretta 84FS depending on where I'm going.

M4 and 870 tac for the house or the zombie apocalypse...

About time they dumped the 5.56 NATO rounds.

See post #15........... The standard infantry rifle isn't going anywhere anytime soon.

No more new calibers! Why do they do this??
