Excalibur Crossbow Troubleshooting and Specs
Most Excalibur crossbow problems trace back to a handful of common causes: string wear, brace height drift, or an arrow/nock mismatch. This page covers troubleshooting basics and where to find accurate specs for your specific model.
Speed (FPS), range, and accuracy figures vary by model and package, so always check the specific listing for your crossbow rather than assuming one number applies across the whole lineup - Excalibur's current packages range from roughly 350 FPS up to 435 FPS depending on the model.
Common accuracy problems
If groups start opening up unexpectedly, check brace height first, then inspect the string and rail for wear, and confirm the scope's speed dial still matches your arrow setup. Arrow and nock mismatches - using an arrow line not matched to your crossbow's series - are another common, easily overlooked cause (see Arrows & Bolts).
Noise and vibration problems
Excess noise or vibration on the shot is usually addressed with rail lubrication and dedicated dampening accessories rather than treated as a defect - see Silencers & Sound Dampening for the specific parts that target limb, string, and stirrup noise separately.
Finding accurate specs for your model
Because Excalibur's current lineup spans multiple speed tiers - the Mag Max around 350 FPS, the Rev X around 400 FPS, and the Hybrid X around 435 FPS - always confirm FPS, draw weight, and overall length against your specific model's own listing rather than a general figure, since these vary meaningfully across the range.
When to contact Excalibur directly
For a problem that doesn't resolve with basic maintenance - persistent limb noise, a trigger issue, or anything involving the crossbow's structural components - contact Excalibur directly or an authorized dealer rather than attempting a DIY repair on a load-bearing part. See our dealer locator for help near you.
