Sig Sauer MCX-SPEAR LT IR in 300 Blackout
This is the Sig Sauer MCX-SPEAR LT IR pistol in 300 Blackout, with a 9″ barrel and a Gen II NiR FDE Cerakote finish. The IR coating is made to reduce visibility under thermal or night vision. This SKU is the pistol version, not the short-barreled rifle, and it ships with a folding PCB brace.
Barrel and action
The barrel is 9″ of cold hammer forged carbon steel, with a 1:5 twist and 5/8″-24 threads. A SIG QD suppressor-ready flash hider is on the muzzle. The gun uses a gas piston and has an adjustable gas system. Barrels on the MCX-SPEAR LT can be swapped.
Controls and brace
Controls are fully ambidextrous. The trigger is a SIG Flat Blade Match with a flat face. The PCB brace folds for storage; overall length is 27.5″, or 19.30″ folded. The alloy handguard has M-LOK slots, and a Picatinny rail runs along the top. There is a forward assist. No iron sights or optic are included.
What comes with it
One 30-round polymer magazine. It takes AR-15 pattern magazines.
