Overview

The FOSTECH STEALTH RAPTOR is engineered as one of the lightest, most accurate AR-15 rifles available, tipping the scales at an unloaded base weight under 5.5 lbs. Built around a 16″ Faxon Gunner Series barrel chambered in 5.56 NATO, the rifle blends range performance with real-world handling for defensive and multi-purpose roles.

Key features and materials

The 16″ Faxon Gunner Series barrel is produced from 4150 CMV steel with a 1:8 twist rate — a practical choice that stabilizes a wide array of bullet weights commonly used in 5.56 NATO applications. The combination of a lightweight Mach-1 16″ M-LOK compatible rail, Fostech’s proprietary billet aluminum/magnesium alloy receivers, and a Low Mass Nickel Boron bolt carrier group reduces weight and felt inertia while improving reliability under sustained use.

Ergonomics and control

Factory-installed components like the Fostech Echo II trigger, Fostech Sabre grip, MFT Minimalist 6-position stock, flip-up sights, and the Strake muzzle device create a balanced, combat-ready package. A 30-round magazine, hard case, owners manual, and warranty cards are included, making it range-ready out of the box.

The 1:8 twist and 5.56 NATO chambering offer flexibility across bullet weights from lighter 55–62 gr loads to heavier 69–77 gr rounds for extended-range work.
