SIG Unveils Suppressor-Integrated MCX Upper at SHOT Show 2018
SIG Sauer introduced a suppressor-integrated MCX upper at SHOT Show 2018, designed to simplify NFA compliance for SBR builds. This piston-driven system features a 6.75-inch barrel with a pin-and-welded 7.62 Titanium suppressor, achieving a 16.75-inch overall length. It offers plug-and-play compatibility with existing MCX lowers and includes an adapter for standard M4 lowers, potentially solving SBR tax stamp issues for Virtus pistol owners.
