Choosing 7.5" Cobra R9 / Adder bolts
The 7.5" bolt is closely associated with the modular EK Archery Cobra R9 / RX / Adder platform. Different bolts and configurations exist within this system, however, so length alone is not enough to determine whether a bolt is suitable for your crossbow.
When choosing a bolt, consider its weight, material, nock and compatibility with the crossbow and magazine. Correct fit is particularly important with repeating crossbows to ensure reliable feeding from the magazine.
If you use a modified or higher-powered Cobra configuration, for example with a different front end or upgrade kit, also check the bolt type and bolt weight specified for that configuration. A bolt that physically fits the magazine is not automatically suitable for every power configuration.
For other Cobra configurations, the Crossbow Bolts section also includes a dedicated category for 15" Cobra R-Series / Siege bolts. Separate categories are available for other compact crossbow bolts, including 6.5" short crossbow bolts.
Important when choosing Cobra bolts
Do not choose a bolt based on its 7.5" length alone. Always check compatibility with your Cobra R9, RX or Adder, the magazine being used and the power configuration of the crossbow.
