Description Technical Specs
 
NEW VERSION! The QB78 Repeater Upgrade Kit allows any QB78-type air rifle to be upgraded to 10 shot self indexing repeater operation. This includes the AR2078 and AR2078A models. The kit also fits Tech Force TF78 and TF79 models in exactly the same way.

This 35-piece kit comprises all the parts required for “drop in” installation using simple hand tools, with no fitting, filing or modification required. This new version is also easier to assemble than the previous version. Even better, the Repeater Upgrade Kit can be removed if required and the air rifle converted back to it original single shot configuration (so long as you save the original parts, that is).

Compared to the standard, single shot version, the QB78 Repeater offers:
  • Multi shot capability using readily-available Benjamin Marauder 10-shot magazines.
  • An XP Tune Kit-type bolt giving a muzzle velocity increase of over 100fps.
  • Cock on opening action for improved feeding.
  • Rear breech locking slot for easy magazine loading and use as a second safety.
  • Superior accuracy due to the longer breech and 2 setscrew barrel anchoring.
  • Longer breech dovetails for increased scope mounting flexibility.
  • Riser breech design allows for potential fitment of shrouds etc where legal.
  • Breech plug eliminates the possibility of pellets falling into the hammer mechanism.

The QB78 Repeater Upgrade Kit contains high quality US-designed, CNC manufactured parts, including:
  • Precision, anodized aircraft grade Aluminum breech.
  • High flow steel bolt.
  • Steel hammer pin.
  • Barrel band.

Other parts included are:
  • Specially-machined, replacement AR2078 barrel.
  • Cock on opening Hammer, cocking block and power adjustment shims.
  • AR2078 Muzzle weight (fits in place with epoxy).
  • Benjamin Marauder magazine.
  • 4 x bolt probe O rings (2 are spares).
  • 6 x barrel O rings (3 are spares).
  • Rear trigger assembly screw.
  • Rear trigger assembly screw washer.
  • Breech screw.
  • Breech screw washer.
  • Front barrel setscrew.
  • Rear Barrel setscrew.
  • Breech plug.
  • 2 x breech seals (1 is a spare).
  • Allen wrench.
  • Installation guide.
  • Owner's manual.

Please note that some kits will have a muzzle weight, others will have no muzzle weight but iron sights fitted to the barrel. This variability is due to parts availability issues.

The QB78 Repeater requires a scope for use (not included).

Best Upgrade Ever December 19, 2013
Reviewer: John Hooper from Greer, SC United States  
This is the best after market upgrade item that I have ever seen. Great quality, quick service, American made, extreme accuracy, easy installation. What more can be said. Oh yea, great value for the dollar. Takes Crosman Premier pellets and stacks them one on top of the other.
