O Ring Mod
a Talon or Condor is fired, some of the pressurized air escapes around
the valve stem due to an ineffective design from the factory. This is
not only uncomfortable to the shooter due to the air pulse, but also
wastes valuable air.
This option is not part of a full tune. It is a $50.00 add on price
and is essential in quieting your rifle.
With an O-Ring Mod a precise groove is cut in the brass valve insert, and a 90 Durometer O-Ring is inserted. This gives
a much better seal which eliminates the wasted air, makes the rifle
quieter and more comfortable to shoot.
