SIG Sauer MCX Rattler LT SBR, 300 BLK, 6.75-Inch Barrel, Black, 30-Round

Description

SIG Sauer MCX Rattler LT SBR, 300 BLK, 6.75-Inch Barrel, Black, 30-Round

The SIG Rattler LT 300 Blackout SBR is the compact MCX. Same short-stroke piston and fully ambidextrous MCX controls, built around a much shorter barrel so the gun stays small without becoming a different platform.

The rail is optic-ready. A factory optic is not installed. SIG fits a QD flash hider meant for SIG SLX and SLH suppressors; that is not a claim that every can mounts. These firearms ship to a licensed FFL.

This configuration

This SBR puts a folding stock on a 6.75 in. cold-hammer-forged 300 BLK barrel. You still get the LT piston, an adjustable gas valve, SIG’s flat-blade match trigger, and fully ambidextrous MCX controls. SIG includes a 30-round polymer magazine. The rail is optic-ready. A factory optic is not installed. The stock folds so the rifle packs down. Twist is 1:5. SIG fits a QD flash hider meant for SIG SLX and SLH suppressors; that is not a claim that every can mounts. Because this short barrel has a stock, it is an NFA short-barreled rifle.

What ships
