NEW SIG Sauer MCX-RATTLER LT 6.75″ 300BLK Upper Assembly

With the new SIG Sauer MCX-RATTLER LT 6.75″ Upper Assembly, you can now convert any M4/AR15 platform into the ultimate suppressor-ready MCX-RATTLER LT style firearm your heart desires. The MSRP is a hefty $1,799, but that is still cheaper than a complete MCX-RATTLER LT if your budget is tight.

Nearly 10 years ago the MCX LVAW was introduced and became the choice of Special Forces groups worldwide. With its 6.75″ 300BLK design, the platform offered a replacement to sub-style platforms because of its ballistically advantageous caliber and a similar size footprint.

Now for the first time since its inception, the MCX-RATTLER LT upper assembly offers that same design that changed a generation of rifles with updated features that make it better than ever, while still offering the same advantages of the original platform.
