ATI GSG FireFly 4″ .22 LR OD Green | GERG2210FFG

The GSG FireFly is a .22 LR semi-automatic pistol with a 4-inch non-threaded steel barrel and a two-tone OD green frame with a black slide. It features an adjustable rear sight, an integrated accessory rail forward of the trigger guard, and black polymer grips. The pistol is described as a compact, range-oriented firearm suitable for training and recreational shooting.

For optic pairing, a compact red-dot such as the Vortex Venom or similar micro reflex sight (under $1,000) complements the FireFly for faster sight acquisition without significantly altering the pistol’s compact profile.
