Power Pack Plus for Pumpers
for Crosman 1322 1377 P1322 P1377 2289

• high performance aluminum valve (with an enlarged chamber to supply more air per shot)
• stronger, high performance hammer spring (part 1 of the Pumper's Pack)
• enlarged exhaust port (part 2 of the Pumper's Pack)

The trio has been available for years for the CO₂ guns, but now pumper fans can enjoy all three performance components, too!

Notes:

• The PPPP kit, as I call it, will NOT work with the first generation 1322/1377 (those having a rear cocking knob on the very back). If you have that era gun, ONLY the power valve will work, which is available separately below.
• If you have a 1377/1322 that came with a plastic breech (and no rear cocking knob) then the trio will work, though you can still buy just the valve if you want.
• If you have a P1377/P1322, then the trio will work or you can buy just the valve.
• The valves are generally safe up to 20 pumps. Enjoy that extra velocity boost, if you want to take the time to pump that much.
