Sig Sauer MCX-Spear LT Upper/Conv. Kit 7.62 X 39 11.5″ Barrel

Sig Sauer MCX-Spear LT Features

This kit introduces a range of advanced features that elevate the standard AR platform. The dual rod recoil assembly effectively eliminates the traditional buffer system, contributing to a more streamlined and efficient design. The M4 adapter enhances the rifle’s capabilities, allowing for the integration of Pic rail folding stocks and expanding the customization options available to the user. An adjustable gas system offers fine-tuning for suppressor use, optimizing performance across a range of shooting conditions.

The quick-change barrel design is a standout feature, enabling users to easily alter calibers and barrel lengths to suit specific needs or preferences. Coupled with a gas piston system that minimizes carbon fouling, the MCX-Spear LT is engineered for longevity, designed to perform flawlessly through 20k rounds before requiring part replacements. The kit also includes a next-gen suppressor-designed QD flash hider for quick adaptability, alongside an ambidextrous charging handle with a gas deflector, enhancing usability for both left and right-handed shooters.
