Hi guys, thanks for tuning in to another video on Forgotten Weapons.com
I’m Ian McCollum and I’m here today in Kreuzlingen Switzerland at the Kessler Auction House taking a look at a magnificently accurate Swiss rifle, specifically a SIG 550-1 Sniper. This was actually not developed for the Swiss military unlike the SIG 550 itself. This was developed, specifically, for the Swiss police forces, which requested it. However, it’s kind of gone on to not be a particularly successful firearm in any other realm and not very many of these have ever been sold. So, mechanically, this is a standard SIG 550 Manufactured to extremely high quality as one would expect from SIG in Switzerland. It is set up with a 25.6 inch barrel 3/4 of an inch in diameter. So a very heavy profile barrel a much longer barrel than standard to get the most velocity out of the 5.56 cartridge Which it is chambered for. These are normally seen with ten round or maybe five round magazines but they do fit all standard SIG 550 magazines. They have mounted a special proprietary scope mount on here with a couple different options in scopes. There was a 10x Hensoldt, I believe, and then this is actually a 1 1/2 to 6 power Hensoldt scope Very nice optics. This one has tritium for use at night They fitted a special buttstock on here which is adjustable in about 37 different ways and a very nice trigger on it.
And, oh, and a very nice bipod on it! Everything about this rifle is very nice as again one might predict. When these came into the United States in 1989 only a very small number of them came in before the US banned the importation of assault weapons and this qualified The ones that came into the US were priced at something like $10,000 in 1989. So they were extremely expensive rifles and they’re not really that much cheaper for any other markets so as it turns out the only people who have ever really bought these were the Swiss police and apparently the Jordanian Royal Guard. They just didn’t really take off otherwise. Now, let me show you, however What they did to it and in particular We’re gonna take a look inside the trigger so you can see how they changed the trigger mechanism to make it nicer. Here we have the markings on the side. SG 550-1 Sniper. Says so, right there on the gun The fire control system is just semi-auto. There’s no need to have selective fire in a rifle like this. On the buttstock assembly you can adjust the length of pull with this screw wheel You’re probably not gonna see much changing here because these are very finely threaded so you have to crank this quite a ways to see much change.
That of course makes it a little more precisely adjustable. You can actually adjust the height of The cheek rest here with this thumb wheel so you can tilt that up and down Again, it’s very finely threaded, so it takes a while for me to move this before you see a change, but there we go. It’s getting a little higher there You can adjust the position and the angle of the palm rest here and of course being a SIG 550, despite all of these adjustable elements it is still a folding stock. So, it packages up like this to be a little more compact for transportation. So the scope mount here is of course numbered to the gun and has a spring-loaded mounting that holds it in place up on these proprietary mounts on the receiver and it can then be adjusted forward or back for eye relief or Actually, interestingly, it can be adjusted side-to-side. So if you have a cheek weld such that you prefer to have the scope just slightly off from the centerline of the barrel you can do that as well. There is no front sight provided and the dovetail is blocked by this little guy right there because, of course, there’s also no rear iron sight and a rifle like this is kind of pointless with iron sights, so. The bipod on these is a pretty slick bipod. It’s heavy, but it does work very nicely Can fold either to the front… like so, or to the rear or of course, being set up, a little bit of pivot a little bit of swivel Spring-loaded here. You have the feet adjustable for length.
So you can stretch those out to about double their resting their fully recessed positions And then each of the feet has this rotating rubber; fairly large rubber foot pad, So, these will just automatically conform to whatever surface of the ground you put them on and that actually makes for a very stable mount on the rifle. On the outside, the trigger looks different because of the addition of this the very wide trigger shoe but it does also look different on the inside and it’s largely a combination of the trigger pull, the improved trigger mechanism and Just the stand that the general quality of the construction and the assembly that makes these a good, legitimate, 1 MOA gun in the field Up on top here, I have a regular semi-auto STG 90 lower receiver and fire control group and on the bottom here is our 550-1 Sniper. and there’s really only one substantial change that was made and that is the actual trigger spring the trigger return spring. So, on the standard rifle, there’s a coil spring wrapped around the trigger access pin. On the Sniper model they have gotten rid of that and they instead have a coil spring that runs down into the grip You can see it right there. Connected to the back of the trigger. So that is a spring that’s going to be pulled in tension and in a regular 550 you have a torsional spring doing this work. This increases the take-up weight of the trigger substantially. Which is done for a purpose, that makes it more drop safe. However, when you want a very nice, very light, and crisp trigger pull that torsional spring is going to be just way too heavy. You don’t want to try and cut it down Instead, they just went to a totally different system. Now I’ll tell you what, the trigger on this is really really nice. As it turns out, most of the time, when someone wants a sniper rifle, whether they are police or military, they usually want a heavier cartridge– a heavier caliber than 5.56×45 millimeter So this rifle, in its price point was competing with things like HK’s PSG1 Which offers pretty much all the same benefits. Pretty much about the same weight but firing a much heavier cartridge. And so, the 550-1 Sniper was never able to develop a very serious commercial market. So, as a result, they’re quite rare, and it’s very cool to take a look at this one today. Hopefully you guys enjoyed the video as well. If you’re interested in buying this yourself, and you are legally in a position to do so in Europe well, check out the Kessler Auction House. They regularly have very cool things like this. Thanks for watching.
