Also known as: Super Duty Rifle, Super Duty MOD1-A
Overview
The Geissele Super Duty MOD1 is a duty-grade 5.56 NATO AR-15 rifle assembled from Geissele's premium component ecosystem. It pairs a cold-hammer-forged, chrome-lined Geissele tapered-profile barrel with a 15" MK16 M-LOK rail, the Super 42 buffer assembly, the Reliability Enhanced bolt carrier group, and the SSA-E X two-stage trigger with the Lightning Bow shoe. Designed as a turnkey law-enforcement and serious-civilian carbine, it is positioned as a step above standard mil-spec ARs in fit, finish, and parts quality.

Notes

Background
Bill Geissele built his name selling triggers good enough that special operations units would pay out of pocket for them. The Super Duty is what happens when a trigger company decides that the rest of the rifle wrapped around their trigger should be just as nice.
