I wanted to do a quick write up on an interesting concept from Sig. I managed several months back to score a Sig Rattler at a local FFL. Sourcing one proved to be harder than expected and in my home state of Arizona, I was only able to find two locations that had the Rattler in stock. Once I got it home I opened the box and found that the weight seemed to be heavier than the 5.2 pounds seen online. I am not sure if this is due to the added weight of the telescoping arm brace compared to the folding stock of the SBR version, but the gun seems significantly heavier than 5.2 pounds. The fit and finish are great the angle of the pistol grip is different than a standard AR-15 and lends itself well to the balance of such a short weapon system. With a 5.5-inch barrel and those that have any experience with K configured MP5’s the addition of a hand stop would be a major improvement. This would have been a nice addition to the civilian guns as the K configured MPX comes with one standard. The three-position pistol brace seems well constructed with some lateral play in the brace.
Shooting the Rattle at an indoor range would not be a fun experience for those in the bays next to you but luckily, I had the range to myself on the day of initial shooting. I was able to get decent groupings at twenty yards. (I am planning to take the Rattler out in the desert in the next week for longer distances as well as testing the platform suppressed.) The recoil was negligible from the 5.5-inch barrel shooting .300, one gripe that I do have for the rattler is the brace, it is uncomfortable and makes an otherwise manageable weapon system unpleasant to shoot. The braces telescoping design adds unneeded length (versus the side folder) and also gets into the way of the charging handle, with that said I will be SBRing my Rattler. In the meantime, I will most likely be swapping out the brace for a tail hook as I am iffy with the SBA3 using a carbine buffer tube. The trigger feels like a standard GI trigger and is nothing to write home about. The Ambidextrous controls are well thought out and comfortable to use in both strong and support side shooting.
Overall, I think the concept of having a piston driven .300 Blackout in roughly the same package length as an MP5K is an interesting one and with more units moving away from short barreled 5.56 is something needed. Some improvements I would like to see are the inclusion of a hand stop, a better pistol brace, and an improved trigger. At $2,719 MSRP the Rattler is not cheap and at this price point should come with a hand stop at least. The pistol once you throw concepts of comfort out the window is easy to shoot and recoil is manageable allowing for quick follow up shots. As of magazine compatibility, I have used the included Lancer magazine, GI, Pmag (.300), and they have all run flawlessly. In my opinion, the Rattler is a fantastic gun and with its two-position gas system screams to be suppressed.
