The GAMO HPA IGT Rifle 19.9 Joules is a precision-engineered break-barrel airgun utilizing Inert Gas Technology (IGT) for smooth cocking, consistent power, and reduced recoil. Chambered in .177 (4.5 mm), it delivers up to 19.9 J (≈14.7 ft·lb) of muzzle energy, making it ideal for target shooting and small-game hunting. The 10-rifled steel barrel provides enhanced pellet stabilization and velocity consistency, while the integrated Whisper Maxxim moderator reduces noise by up to 52% compared to unmoderated designs. The black synthetic stock features an ergonomic Monte Carlo comb, ventilated rubber buttpad, and textured pistol grip panels for secure handling in all conditions.

Included is a 3–9×40 WR (Wide Rimfire) scope pre-mounted on an 11 mm dovetail rail, offering clear optics and variable magnification for precision at varied distances. The two-stage adjustable trigger allows shooters to dial in pull weight between 150–350 g for a crisp, predictable release. A quick-change 10-shot rotary magazine enables rapid follow-up shots without manual pellet loading. The manual safety engages automatically when cocking, resetting after each shot to ensure secure handling. Underlever cocking linkage provides smooth leverage while maintaining a compact profile.

An integrated air pressure gauge on the right side of the cylinder indicates remaining reservoir pressure, allowing users to monitor fill levels and maintain optimal performance. Refilling is accomplished via a quick-fill probe compatible with hand pumps, scuba tanks, or carbon fiber cylinders. The included bipod mounts to the integrated swivel studs on the fore-end, offering stable support for precision shots in prone or bench-rest positions. Detachable side panels grant easy access to internal components for maintenance and cleaning. The matte black finish on the metalwork resists corrosion and minimizes glare.

Whether plinking in the backyard, honing your marksmanship, or hunting small game, the GAMO HPA IGT Rifle 19.9 Joules with 3–9×40 WR scope and bipod delivers a balanced combination of power, accuracy, and ergonomic comfort. Its modular design and durable synthetic construction ensure reliability for shooters of all skill levels.
