Gamo R77 “Laser” CO₂ air pistol in 4.5mm / .177 calibre.
Made in Spain during the mid‑1990s to early‑2000s. Alloy‑frame construction with steel barrel insert and the desirable factory‑integrated laser module. Revolver‑style action and supplied in its original foam‑lined case.

Condition
Overall finish is Very Good to Excellent with no corrosion visible. Cylinder and barrel show only light handling wear. Laser warning label intact. Grips clean and undamaged. Includes case, CO₂ cartridge and pellet tin.

Power & Performance
Runs on standard 12g CO₂. Typical muzzle energy 1.8–2.5 ft‑lbs with velocities around 300–380 fps using steel BBs. Slightly lower with pellets due to weight. Temperature‑dependent performance (warmer = higher fps). Suitable for plinking, cans and paper targets; not suitable for pest control.

A well‑kept example of Gamo’s classic CO₂ revolver with the rare factory laser module.
