SIG Sauer’s new MCX-SPEAR LT rifle marks the third generation of the company’s MCX platform. Available in three calibers: .300 Blackout, 5.56 mm NATO and 7.62x39 mm, the latter is making its first appearance in the MCX rifle family.

SIG MCX-SPEAR LT
The SIG Sauer MCX-SPEAR LT rifle weighs between 5.6 and 7.6 pounds, depending on the model. All have a Coyote Anodized finish.

The MCX-SPEAR LT is an aluminum frame rifle with a gas piston operating system and a cold-hammer forged carbon steel barrel. Available barrel lengths are nine inches (.300 Blackout), 11.5 inches (7.62x39 mm and 5.56 mm NATO) and 16 inches (7.62x39 mm and 5.56 mm NATO).

A new latch system was developed for the MCX-SPEAR LT so that it can cycle many types of 7.62x39 mm ammo reliably.

The SIG QD suppressor-ready flash hider is optimized for SIG QD suppressors, and there is also a SIG flatblade match trigger. Additionally, the MCX-SPEAR LT will accept AR-15 style triggers.

With a lightweight ergonomic handguard and push-button folding stock with cheekrest, the MCX-SPEAR LT rifle also has fully ambidextrous controls including bolt catch and release.

In addition, this rifle is optics ready, and can be quickly paired with a SIG Sauer ROMEO8 or TANGO6T optic.

About the design of the new MCX-SPEAR LT, SIG Sauer says it “incorporates the best of both generations and is the culmination of the latest research, development and innovation in the MCX platform.”
