Below are four different rifles, in four calibers, from SIG Sauer – Swiss Arms, as presented at the IWA exhibition in Germany 2016. Of course, they had more rifles in their stand but let’s focus on the ones below and the news in particular.
The SG 553 is also known as Stgw 04 and used in the Swiss Forces. It’s specially made for special units, paratroopers and the AAD 10 (The Army Reconnaissance Detachment.)
At IWA they presented the 300 Blackout version, with a semi auto suppressor attached.
IWA is a civilian exhibition, so there are no fully automatic firearms around.
Below: SG 553-BK in 300 Blackout. As you can see on the receiver it says “Prototyp 1 300 Blackout“, serial number 0001. “16” is most likely because it was made in 2016.
The prototype has no Picatinny on the fore end.
Note the end cap before the stock is not yet anodized, as in prototyping.
“Semi Auto Suppressor” – Serial SD00001.
Note the gas switch for suppressed or non-suppressed.
SG 553 R in 7,62×39. These don’t have the fun switch, but they are supposed to accept the common AK47 magazine.
SG 553 R in 7,62×39 from the other side. This rifle has a different grip to the 300 BLK.
Below: The SG 553 CH in .223 Rem. Note the front Picatinny.
SAN Swiss, SG751 in .308 win.
