Description

Nearly 10 years ago the MCX LVAW was introduced and became the choice of Special Forces groups worldwide. With its 6.75” 300BLK design, the platform offered a replacement to sub-style platforms because of its ballistically advantageous caliber and a similar size footprint.

Now for the first time since its inception, the MCX-RATTLER LT upper assembly offers the same design that changed a generation of rifles with updated features that make it better than ever.

The MCX-RATTLER LT offers a 6.75” cold hammer forged barrel, compatibility with AR-style triggers, an adjustable gas system for suppressor optimization, a QD Clutchlok Muzzle Device and a M4 adapter kit to convert any M4 lower to utilize the folding capability of the MCX platform. Also, the new MCX-RATTLER LT design allows it to be compatible with all MCX-SPEAR LT parts, meaning any barrel or handguard from the MCX-SPEAR LT can interchange parts, allowing for easy caliber and length conversions. Advanced beyond any platform in its class, the MCX-RATTLER LT upper is the ultimate upgrade for your MCX or M4 lower.

Features:

Adapts with any M4/AR15 spec lower assembly
Dual rod recoil assembly eliminates buffer system
M4 adapter allows for pic rail folding stock capabilities
Adjustable gas system for suppressor optimization
Quick change barrel design allows to easily swap calibers and barrel lengths
Gas piston design reduces part exposure to carbon fouling
Designed to go 20k rounds before any part replacements
SLX/SLH Next Gen Suppressor designed QD Flash Hider for Clutch-Lok adaptability
Ambidextrous charging handle with gas deflector
Replaceable parts (cam path follower, feed ramp, forward assist/deflector, charging handle locking pins) allow for longer receiver life over standard AR designs.
Tapered bolt design functions more reliably and lasts longer than standard square lug M4 bolt designs.
Nitride coated cold hammer forged barrel for optimal accuracy and barrel life
