Sig Sauer Rattler - Most of you will probably understand when I say I have a list of guns I want to own one day, but it's always followed by "if I win the lottery." I have a few of those guns on my list, but when I saw the new MCX Rattler from SIG Sauer, I felt like it was something new on the market and that excited me. I checked it out at SHOT Show and last year's NRA annual meeting. I've always thought it was a useful system and again I'm interested in pulling it off. Fortunately, I found one and had the opportunity to buy it, so I did! Let's go into what I think a year later.
First of all, the gun packs a big punch for a very small package. The total length from the banana to the end of the stick is about 16 inches. It is also chambered in 300 Blackout with a 5.5 inch barrel. The weight of the rifle without optics is more than 5 kg. It's a pretty small gun built like a tank, but it's not a bad weight. I love that SIG always puts QD mounting points in all their rifles and pistols. The mountains made it really easy to hit one spot and get on with it. I mount my rifle with a Trijicon RMR on an Anvl Ukon mount.

The Anvl Ukon mount has a rail sight system built right into the mount so there is no need for support rails on the rifle. I thought the initial concept was weird, but when I started using it on a PDW system, honestly, I don't think there is a better option on the market right now. I was initially interested in this optic setup because there are a number of special forces teams around the world that use the MCX Rattler with the Trijicon RMR on a Ukon mount. It's easy to see why they went with this setup! I threw in a Surefire M300 Mini Scout gun light with a single Point Phase 5 scope and called it good.

So far I've put about 3,700 rounds of MCX Rattler on it, and it's been 100% reliable. I average 1.5" groups at 100 yards. Unless you consider the fact that it only has a 5.5" barrel. The gun is an absolute blast to shoot and the recoil is extremely smooth. I was amazed at how easy it is to stay on target during practice or pass shooting and even though it is a very small package the gun doesn't blow you away with a burst of flies or large bullets. My gun came with a SIG concealment plug and it works fine. Work to reduce the explosion of music.
However, there are a few things you need to know when it comes to using the MCX Rattler. The first thing I'm not a huge fan of is the small charging handle on the gun. I fully understand that it is a PDW gun so everything is done properly and reduced as much as possible. The carrying handle is very compact, which is great for pulling out a hidden carry bag. The downside to this is that it is very difficult to use while loading the gun. I changed mags a few times on the trail and my knees were raw by the end of the day, but it wasn't a compromise.
I picked up a Geissele Super X charging handle for the Rattler which fixed the problem. The next thing I changed on the gun was the loose piston ring. The strap was adjustable, which is a plus, but I would have preferred a padded strap that was easy to put on. The collapsible stock is really well made, but you need two hands to deploy quickly. The side-pull buckle takes only one hand to deploy quickly. This is my personal preference, but again it's a very minor issue on an otherwise fantastic weapon. Both of these problems are easily solved with the SB Tactical Side Folding carrying handle and neck.
When I first picked up the MCX Rattler, I was really worried that it wouldn't live up to my high expectations. After owning and wearing it, I am happy to say that it did not exceed my expectations. The rifle is fast moving and packs a lot of firepower into a small package. I love the fact that I can throw it into a single belt bag and carry the Rattler without a problem or it looking bulky.

I'll probably buy a new Vertx bag for the Rattler and post what I think about it. In the next 6 months I am planning to move so I will be traveling with me. I plan to update you with my experiences with the Rattler, but after 1 year it has been fantastic. As always, feel free to email me if you have any questions or comments.

I am an avid shooter and love to learn, whether it is in my job or in the shooting community. I'm an average Joe who really enjoys talking to others about guns and other hobbies. I knew that SIG was working on a new, compact version of the MCX. They had been refining this design for a while, having heard rumors about it overseas during DSEI two years ago. Then, after asking about it, I was shown the development models. Today everything becomes clear. SIG SAUER launches the Rattler, the latest addition to the MCX family. I had a chance to talk briefly about the rifle with Patrick Hanley, Rifle Product Manager at SIG.
The first question I asked was about the name. I heard it rattle for a while and wondered where it was coming from. Apparently, after shooting it fully-automatic for the first time, the designer said, "It literally rattles your teeth when you fire it." Given the name MCX, the Rattler stood out.

After that I asked him why they built it. "Everything is designed to be as smart and small as possible with this gun," Hanley replied. Quite simply, customers came to them asking for a large 5.56mm or .300 BLK Subgun. This is the result of that work.
At first they used the MCX short-stroke piston design, but quickly realized that the upper would have been longer than the 5.5″ barrel. Instead, they developed two separate gas systems, one for the .300 and the second for the 5.56.
The .300 gas system has two positions and can be used with suppression. 5.56 is a sealed gas system to prevent valve corrosion. Unfortunately, it cannot be used with a suppressor; not at that length. However, switching between calibers is as easy as switching barrels.
The stock is designed so that all the controls can be manipulated with the shutter closed and the gun itself is fired with the stock closed, making it a very compact package. Additionally, the Rattler's upper receiver lacks its forward assist and side deflector for expendable cases.

SIG may have succeeded in creating the smallest AR-style handgun in the world. 16″ when folded and 23.5″ with the stock extended.
Based on these differences, the Rattler comes as either a complete cat (with SPB) or an SBR. The barrels are not compatible with any other MCX upper, so SIG offers Rattler Upper Receiver Kits that come with an AR lower adapter bolt. The Rattler upper kit can be used with the MCX lower or the AR lower, when used with the adapter bolt. For Rattlers owners, barrel kits to change calibers will be available so they don't have to buy complete URGs.
