Key Features and Tactical Advantages
The MCX SPEAR-LT IR sports an alloy steel receiver with a Flat Dark Earth Cerakote Picatinny rail and M-LOK handguard for accessory mounting.

The FDE folding brace with a push-button hinge improves transport and storage while retaining a stable firing interface when deployed. Interchangeability with all MCX LT barrels and handguards lets users reconfigure barrel lengths or calibers within the MCX LT family without replacing the entire platform.
