The heart of this Super Duty is a 16.1" cold-hammer-forged, chrome-lined barrel with a durable phosphate exterior and a 1:7 twist for optimal performance across standard 5.56 NATO projectile weights.
Geissele’s Nanoweapon-coated Reliability Enhanced bolt carrier group resists wear and corrosion while running smoothly in the direct-impingement system. The Super 42 braided buffer spring further mitigates recoil impulse and improves reliability.
A Geissele-length mid-gas system balances dwell time for consistent cycling, and the Maritime bolt catch, ambidextrous magazine release, ambidextrous selector, and ambidextrous charging handle give both right- and left-handed shooters intuitive control.
The 15" Geissele SMR MK16 free-floating handguard is machined from aluminum, features M-LOK slots along its length, and includes stainless press-fit QD sling cups for flexible accessory and sling placement.
The SOPMOD-style collapsible stock, flat-faced two-stage Lightning Bow trigger, and hard-coat-anodized 7075-T6 receivers round out a well-equipped package built entirely in the USA.
