SIG Sauer Unveils Two New AR-15 Upper Receivers for Enhanced Performance
SIG Sauer has announced the release of two new AR-15 upper-receiver assemblies: the MCX-SPEAR LT 9-inch Upper AR Conversion Kit and the SIG AR Upgrade Kit. Both products are designed to enhance the performance and versatility of AR-15 platforms.
The MCX-SPEAR LT, priced at approximately $2,499.99, is a 9-inch upper conversion kit chambered in .300 Blackout. It is part of SIG Sauer's MCX-SPEAR LT family and offers a durable design that can withstand up to 20,000 rounds before maintenance. Key features include a dual-rod recoil assembly, adjustable gas system, quick-change barrel design, and ambidextrous charging handle. It is designed for AR15 lower conversion, allowing for SBR or pistol configurations with a stock or brace.
The SIG AR Upgrade Kit, priced at $1,199.99, includes a complete 16-inch 5.56 NATO upper assembly, a SIG 2-Stage Matchlite Duo trigger, and a Tango-MSR LPVO 1-6X24mm riflescope. Its handguard features a new steel lockup design, reducing handguard deflection and enabling accessory attachment on all four sides. More details about these products are available at sigsauer.com.
Both the MCX-SPEAR LT and the SIG AR Upgrade Kit are designed to provide shooters with enhanced performance and versatility. The MCX-SPEAR LT offers durability and flexibility in .300 Blackout, while the SIG AR Upgrade Kit provides an upgrade path for existing AR-15 platforms with a high-quality upper assembly and optics.
