  "BOSS MAX" Modified High Output Valve Assembly 

for Crosman CO2 Models 

2240 2250 2260 2300 2400 1740 1760 

Air Guns (pellet pistols, carbines, rifles).

  • This is a modified valve for your Crosman CO2 air gun.
  • We recommend this valve for maximum CO2 power in guns with barrels 18" and longer.
  • For barrels 18" and shorter, we recommend our Boss RP valve.
  • NEW FOR 2020 and beyond, this has more mods that matter than ever before.
  • There is none better that I am aware of or it would be here instead.
  • It has a newer larger-than-before CO2 chamber  
  • It has the exhaust / feed port angled for more efficient flow.
  • Now we have also made the valve internal spring weakened so that the valve stays open a fraction of a second longer to help push that pellet in that longer barrel farther and faster.
  • No doubt about it, you can count on more power / feet per second with this valve with longer than stock barrels especially.
  • This modification is second only to large increases in barrel length for adding power to your air gun.
  • You can expect to use more CO2 as well.  Just like putting a race engine in a car, your mileage will vary upward. 
  • Our valves are tried and true modification with many hundreds of satisfied customers.
  • The exterior dimensions and internal parts' workings are still the same, so it is install and shoot. 
  • This Custom part is freshly new (not old stock) and has never been used.  
  • It has been disassembled, modified, tested and reassembled.
  • It is a complete valve assembly and does include all of the internal parts: Piercing stem, Valve spring, valve o-ring, and CO2 gasket / seal. 
  • This part is completely ready for you to install to your CO2 tube and have some fun !
