Description

SIG Sauer MCX Spear-LT IR Features This 15-round configuration of the MCX Spear-LT IR runs a 16 cold hammer forged barrel with a 1-in-7 rate of twist holding accuracy steady across standard 5.56 loads. The semi-auto action cycles reliably and the SIG hybrid compensator/flash hider manages recoil and muzzle signature together though it is not Loctited at the factory and should be checked for tightness before firing. The SIG flatblade match trigger gives a consistent predictable break shot after shot and the threaded barrel allows shooters to add their own muzzle device or suppressor. For shooters in capacity-restricted states who still want full-platform performance this configuration gives up nothing but magazine capacity. The Gen II NiR FDE Cerakote finish remains the standout feature here built to reduce infrared reflectivity for night vision operations where a standard finish would stand out under illumination. At 7.36 lbs. the Spear-LT IR stays manageable in hand and fully ambidextrous controls including the safety selector keep every function reachable for right and left handed shooters alike. The SIG folding/telescoping stock collapses the rifle from 35.6 extended to 26.8 folded for compact storage or transport and the optics ready receiver cut accepts a shooter's preferred red dot or optic. For hunters and professionals operating under capacity restrictions the reduced-signature finish and collapsible stock still deliver. Like the rest of the MCX LT lineup this rifle accepts the full range of MCX LT barrels and handguards so the platform can be reconfigured without buying into a new host. It ships with one 15 round magazine and carries the same SIG Sauer build quality as the standard-capacity Spear-LT IR. For self-defense hunting and training in jurisdictions with magazine capacity limits the SIG Sauer MCX Spear-LT IR is for sale at ARMSAGORA.
