Sig Sauer MCX Spear LT 5.56 NATO 16" 30+1 Semi-Auto Rifle

The Sig Sauer MCX Spear LT is a modern tactical Semi-Auto rifle chambered in 5.56 NATO, built around a black anodized alloy receiver with an integrated Picatinny optics rail. It pairs an AR-compatible lower layout with a clean, modular upper for familiar handling and easy accessorizing.

Up front sits a 16" threaded barrel with a 1:7" twist, capped by a SIG QD flash hider that is Rocksett-pinned in place for permanent, secure attachment. The slim M-LOK handguard offers a free-float mounting surface for lights, lasers, and other accessories, while the adjustable Minimalist Plus side-folding stock brings overall length from 32.50" to 34.30".

Feeding from AR-compatible 30-round detachable magazines for a 30+1 capacity, the rifle features fully ambidextrous controls - including the safety, magazine release, and bolt catch - and a crisp two-stage Matchlite Duo trigger. The AR-compatible reduced angle grip keeps the manual of arms familiar to anyone trained on an AR-platform rifle.

At 7.40 lbs, the MCX Spear LT strikes a strong balance between portability and control, making it well-suited to home defense, duty carbine use, and modern sporting rifle competition.
