US Armor Forge has launched the LVA2 titanium rail system, designed for the Sig MCX Virtus, MCX LT, and Rattler platforms. This next-generation system features configurations optimized for .300 Blackout barrels, offering enhanced rigidity, heat dispersion, and superior performance compared to aluminum. The versatile modular system caters to professional users.
LVA2™ Rail System For SIG MCX Virtus & MCX LT Platforms. Next-Generation Titanium Rail Architecture — Engineered for 6.75” & 9” .300 Blackout Systems The LVA2™ for the MCX Virtus and MCX LT is the evolution of our titanium ISR rail system — redesigned specifically around 6.75” and 9” .300 BLK barrel configurations. Manufactured entirely from DMLS 3D-printed Ti-6Al-4V Grade 5 titanium, the LVA2 delivers unmatched rigidity, superior heat dispersion, and zero-retention performance that aluminum rail systems cannot replicate. Purpose-built for suppressed platforms. Optimized for professional end-users. Designed to outperform.
For SIG MCX Virtus & MCX LT Platforms CONFIGURATIONS:
- SMALL — 6” LVA2: Engineered for the 6.75” .300 BLK barrel, the 6” LVA2 provides ideal suppressor clearance while maintaining the shortest effective footprint.
- MEDIUM — 8.5” LVA2 (MDK Compatible) The 8.5” configuration is the most versatile rail in the Virtus/LT lineup — and the only model compatible with the MDK Modular Accessory System. Optimized for both 6.75” and 9” .300 BLK barrels, this configuration provides balanced control while enabling forward modular expansion.
- MDK™ Modular Accessory System (8.5” LT Only)(Release Shortly): The MDK system seamlessly integrates into the 8.5” LVA2 rail, extending overall length by approximately 4 additional inches without compromising rigidity or zero retention. The extension locks directly into the titanium chassis architecture — not as an add-on clamp system — but as a structural continuation of the rail itself.
LVA2™ Rail System For SIG MCX Rattler 5.5 Platform CONFIGURATIONS:
- 5” LVA2 – SHORT :Ultra-Compact. Maximum Control. Purpose-built for the 5.5” Rattler configuration, the 5” LVA2 Short maintains the platform’s compact footprint while dramatically increasing rigidity and thermal management.
- 8.5” LVA2 – MEDIUM Extended Control. Balanced Profile. The 8.5” variant provides increased forward grip surface and enhanced laser stability while maintaining suppressor clearance for advanced setups.
- 9” LVA2 – MARITIME (with Diving Board) Mission Extended. Thermal Dominance. The 9” Maritime variant incorporates our integrated titanium “Diving Board” extension for advanced laser bridging and optical alignment across suppressed systems.
