Who this model suits

Choose the PR-776 when revolver handling, an eight-shot pellet cylinder and a substantial 1.0 kg build are more important than compact size. Compare its dimensions with lighter polymer-framed pistols before ordering.

Operation and compatibility

• Use compatible 4.5 mm pellets; this is not listed as a steel-BB cylinder.
• Use the 12 g CO2 cartridge type specified in the manual.
• Confirm pellet length fits the rotary cylinder and follow the manual loading sequence.
