They blur it out in their own media releases, but this is USAF Public Affairs. Maybe they blur the optics out to hide the fact that they use American Trijicon MROs and EO Techs instead of Swedish-made Aimpoints.
Eh, USAF should've blurred them. Great pics nonetheless. I feel safe knowing that special forces in shorts and hawaiian shirts prevent enemy forces from gaining a foothold.
see nobody's focused on how home CNC machines and laser cutters will let people fabricate pretty damn intricate guns, no its all about that 6 shot hunk of plastic that explodes in your hand because there's a political group of edgy techey guys behind it.
3D printing plastic firearms is simply never going to be practical because plastic firearms as a whole are never going to be practical. Laser melting/sintering metal 3D printers can make functioning guns:

But the vast majority of home printers are plastic only, far as I'm aware there are no home DMLS printers at all. Contrast this with the fact that it's actually relatively easy to get your hands on milling, stamping, and casting equipment, and it becomes immediately clear that 3d printing is not an effective means of producing firearms.
Case in point:

This guy was able to take brass shell casings, melt them into a rough outline casting, then work out the details with a milling press and chisel and get a functional lower (the part that's legally a firearm) this is all extremely basic metalwork. Although he did run into a problem due to his use of brass he also managed to do the same with beer cans

The reality of the matter is it's not hard to make a gun, indeed by their very design they're intended to be easy to manufacture on conventional metalworking equipment. The only part that requires dedicated machinery is rifled barrels, which consequently is why so many improvised guns are smoothbore or cannibalize barrels.
I don't see laser sintering printers ever becoming something your average consumer is going to get. I mean I don't see the price of precision optics coming down enough. Right now they're struggling to bring laser cutters down in price and they're still like 6-10,000$ at the low end.

I'm sure someone around here can criticize Ian's pronunciation of Sunngård, but I gotta say he seems downright giddy to finally have gotten his hands on one of these.
Anyone else had several post updates send them to the non-existent page 21?
Die ghost page die!

In the meanwhile, this is my favorite prototype aircraft ever, the XP-79. Way too advanced for its time (September 1945) it crashed on its only flight.
Known glitch with newpunch. Something to do with deleted and OP posts only counting toward the total and page post counts sometimes.
It’s a recurring problem with fast threads
The late 40s were like a time where aircraft could have gone anywhere in terms of design.

I do wonder though what germany and its love for aircraft cannons would have done against one of these though. supposedly it would have been pretty brickish with armor basically everywhere but then jet engines and conventional designs started maturing as the field got serious
Also the D in gård should be silent.
It's more like "sounngohr", for english speakers.
that desing lives forever in your average 1990's shmup

USSOCOM's Suppressed Upper Receiver Group from Sig
Based on the SOCOM requirement, SURG includes an upper receiver group (URG) composed of upper receiver, barrel, operating system assembly and bolt/carrier assembly along with a sound suppressor (may be integral with barrel), operators manual and maintenance manual. In addition to the URG itself, candidate systems could include a folding stock if the operating system didn’t require use of the lower receiver extension, buffer and action spring.
As we can see here, SIG went a different direction than most and used an MCX piston driven upper with detachable suppressor and an MCX folding stock. As part of SURG, SOCOM will receive the folding stock and knuckle adapter for use with existing M4A1 lowers. The suppressor is covered with some sort of aramid-based mesh to protect the hand of the operator. When you get to the performance specs below, you’ll understand why this is so significant.
SOCOM stipulated that SURG could be no more than 25.5 inches in length but that they preferred a system that was no more than 21.0 inches. The barrel has to be at least 11.5 inches in length and the weapon can’t weigh more than 7.0 pounds, but the preferred weight is just 4.5 pounds.
The real meat of the requirement is in the suppressor performance. First off, a SURG equipped M4A1 has to be optimized to fire the M855A1 and the MK318 MOD0 / MOD1 cartridges and be able to do so reliably for at least 1200 rounds without lubrication. Obviously, they also didn’t want anything that could vibrate loose. While the suppressor must be rebuildable, only one component of the suppressor has to be serialized but that part had to last the lifetime of an M4A1 lower receiver (125,000 rounds). The rebuildable components need to last at least 15,000 rounds but SOCOM further challenged industry to make them last for 20,000 rounds.
Additionally, a SURG equipped M4A1 shall not exceed 140 dB ten shot average sound pressure level at shooter’s ear during barrel life minimum (15,000 rounds).
In the past I’ve mentioned the so-called SOCOM suppressor torture or stress test. The SURG equipped M4A1 has to withstand at least 6 complete cycles of the firing schedule seen below below using MK318 MOD0 / MOD1 ammunition with SURG allowed cooling to 120°F after each cycle. However, SOCOM was hoping to complete 20 cycles.
http://soldiersystems.net/blog1/wp-content/uploads/2018/08/img_3867-440x280.jpg
The weapon firing MK318 MOD1 for 5 groups of 10 rounds each suppressed, has to average over the 5 groups no more than 1.50 MOA Extreme Spread (ES) beyond the ammunition Lot Acceptance Test (LAT) average ES at 300 yards. Also, it has to maintain a maximum ES Average of 1.50 MOA over LAT using MK318 MOD0 / MOD1 ammunition from 0 to 10,000 rounds fired.
In addition to that stress test, SURG has to prevent operator contact or sustained contact burns from the suppressor (or equivalent) through 1 layer of standard military duty uniform material after firing 210 rounds in 7 minutes at a rate of 1 round every 2 seconds ± 0.2 seconds. A contact burn will be defined as a peak temperature over 160°F in 1 second of contact. A sustained contact burn will be defined as a peak temperature over 160°F in 5 seconds of contact.
These stringent requirements, combining suppression, reliability, accuracy service life, and operator protection were very challenging for industry. It took three tries at bat for the SURG program to finally select a system. In the two earlier attempts, none of the systems could meet all of the program’s objectives. Kudos to SIG for putting together a winning system.
First Look
That kind of durability on a suppressor seems pretty impressive but I don't really have a frame of reference.
You generally don't want more than a mag through one before things start getting iffy, afik.
Ian just released a video about a Rhodesian SMG called the "Cobra", looks neat.

If they're that "short lived" it could really be a thing for the US gun industry if they could sell rifle suppressors, better for peoples ears and it'd be a steady money earner. Being only for rifles would help avoid it being used for crime.
So how exactly do you stop people putting them on pistols?
ah I dunno much about suppressors.
I assume tho that a 9mm suppressor is p different than a .223 one and you'd need a threaded barrel? I don't know about this sorta thing tho
The biggest difference between suppressors is, as far as I can tell, the diameter of the hole through the centre. So, a suppressor for, say, a .45acp pistol and one for a .45-70 rifle would be basically the same. And yeah, you'd need to have the barrel threaded to fit a suppressor on, but there's other reasons to thread a barrel for non-suppressing muzzle devices, so that wouldn't be too big an obstacle.
Really the only way to restrict what guns a suppressor goes on is to integrate it into the barrel. As long as it's detachable people will find a way to put it on anything they want.
Oh, I meant like at a time. If you don't overheat them by shooting too much (suppressors get hot as all fuck cause you gotta remember, they're just big ol' cans made to catch hot speedy gasses) they'll last forever since there's no real wear on them, but even two magdumps of 30 rounds through a regular suppressor brings it up to temperatures where it might take damage. As long as you only shoot a little at a time and let it cool, a suppressor will basically last forever.
Did you see the video of some guy testing a suppressed M249?
https://www.youtube.com/watch?v=BczhT1ByrXA
Nope, guy I checked used a Beretta ARX or whatever that toy-looking spaghetti-gun is called.
Wow, that's impressive. I don't know the first 2 guns, but the last one is made from a Mosin Nagant originally. I knew they still used them, but it's really cool to see how they turned them into a modernized rifle.
