SIGMCX RATTLER-LT 556, 7.75IN, SBR, BLK

The Rattler LT has the new handguard design seen on the MCX Spear LT. Obviously, though, it is a little shorter. It also incorporates the ambidextrous controls (including right-side bolt catch) seen on the other LT models.

Unlike older Rattler iterations, the Rattler LT has either a 6.75- or 7.75-inch barrel. The original model had a 5.5-inch barrel in .300 Blackout. There are also now three caliber options. Here is a quick breakdown of the current options:

• 5.56 NATO with a 6.5-inch barrel
• .300 Blackout with a 6.5-inch barrel
• 7.62×39 with a 7.5-inch barrel
