Keeping Traditions Alive Since 1953

The original Rattler made its name as the ultra-compact PDW built for Special Operations, and the Rattler LT takes that formula and stretches its legs. This 5.56 NATO version runs a 7.75 inch cold hammer forged barrel with a 1:7 twist, which gives the round enough runway to perform far better than the stubby barrels that came before it. Overall length sits at 27.19 inches with the Pivoting Contour Brace extended, and folding it shrinks the whole thing down to something that stows in a backpack or truck bag without a fight.
Underneath the handguard is Sig's short-stroke gas piston system with an adjustable gas setting, so it runs clean and reliable whether you shoot it bare or hang a can on it. Speaking of suppressors, the muzzle wears Sig's QD suppressor-ready flash hider over 5/8×24 threads, so you can mount up quickly when you're ready. The flat-blade match trigger breaks clean and gives you a consistent feel shot to shot, which is a nice touch on a gun this size. Controls are fully ambidextrous, including the bolt catch and release, so left-handed folks get the same experience as everyone else.
The LT generation is fully compatible with MCX barrels and handguards, meaning this isn't a one-trick setup. Swap barrels, change handguards, and build the configuration you want as your needs change. The alloy M-LOK handguard takes lights and accessories without adding rail weight, and the flat top Picatinny rail is ready for whatever red dot or optic you prefer since the gun ships without sights. It feeds from standard AR-15 pattern magazines and comes with one 30-round polymer mag in the box.
This one makes sense for anyone who wants rifle-caliber capability in the smallest practical footprint, whether that's a truck gun, a home setup, or a suppressor host that stays compact. It's a lot of firepower in a package that disappears when folded, and the build quality is exactly what you'd expect with Sig's name on the side.
Yes, and it's one of the better suppressor hosts in this size class. It ships with Sig's QD suppressor-ready flash hider on 5/8×24 threads for fast can mounting, and the adjustable gas piston lets you tune the gun to run properly whether it's suppressed or not.
It does. The Rattler LT feeds from standard AR-15 pattern magazines, so any mags you already have on hand will work. One 30-round polymer magazine comes in the box to get you started.
Yes, that's one of the biggest upgrades over the original Rattler. The LT generation is fully compatible with MCX barrels and handguards, so you can change calibers or barrel lengths and reconfigure the gun as your needs change instead of buying a whole new firearm.
No, it ships optics ready with no iron sights installed. The full-length Picatinny top rail accepts red dots, holographic sights, LPVOs, or flip-up irons, so you can set it up however you like. A quality red dot is the most popular choice on a compact platform like this.
