Excalibur 16.5" Carbon Quill Crossbow Bolts – 6-Pack
If you own an Excalibur Micro or TwinStrike series crossbow, you know that performance depends heavily on using the right ammunition. The Excalibur Quill Carbon Arrows are specifically engineered to handle the massive energy of these high-output recurve limbs. At 16.5 inches, they are the perfect length for the shorter power stroke of the Micro platform, providing exceptional accuracy, lightning-fast speeds, and the rugged durability Excalibur is famous for. Each bolt is crafted to exacting standards, ensuring your groupings stay tight and consistent, shot after shot. These bolts come equipped with Rhino Nocks (flat-back design), which are mandatory for the safe operation of the CeaseFire Technology found on modern Excalibur models. This system ensures the crossbow won't fire unless a bolt is properly loaded, protecting your equipment from accidental dry-fires. Featuring high-modulus carbon shafts and precision Blazer vanes, the Quill arrows deliver a flat trajectory and maximum kinetic energy, making them the ultimate choice for both target enthusiasts and serious hunters.

Recommended Crossbow Parameters
The Quill bolts are optimized for crossbows with a heavy draw weight, typically between 250 lbs and 290 lbs, where high shaft stiffness (spine) is required to prevent "whip" during acceleration. They are perfectly suited for the Excalibur Micro 340, 360, 380, Mag Max, and TwinStrike models. If you are using a crossbow with a velocity between 300 FPS and 400 FPS, these arrows provide the ideal balance of speed and stability. Always ensure your crossbow specifies a 16.5" minimum arrow length before use.
Expert Maintenance & Safety Advice
Safety first: always perform a flex test on your carbon shafts before every shooting session. Slightly bend the shaft and listen for any cracking or splintering sounds. If you detect any damage, discard the arrow immediately to prevent a catastrophic failure upon release. Keep your Rhino Nocks clean and free of debris to ensure a positive lock against the bowstring. If the fletching becomes slightly deformed, a quick pass with a hairdryer can often restore the Blazer vanes to their original shape.
What to Avoid
- Hard Targets: Never fire carbon bolts into rocks, concrete, or metal backstops. This will cause the carbon to shatter or delaminate.
- Incorrect Nocks: Do not swap the flat nocks for moon nocks if your Excalibur requires flat-back Rhino nocks, as this will bypass safety features and cause damage.
- Unweighted Firing: Never fire the bolts without a field point or broadhead installed, as this changes the spine dynamics and can damage the arrow or bow.
Did You Know?
The Blazer vanes used on these bolts feature a 3-degree offset. This slight angle creates a "corkscrew" effect in flight, much like the rifling in a gun barrel. This rotation stabilises the arrow much faster than straight fletching, which is particularly important when using broadheads that might otherwise catch the wind and drift off-course.
Recommended Accessories
To get the most out of your Quill arrows, we recommend using 100gr or 125gr Field Points for target practice. A high-quality arrow puller is a lifesaver for removing these high-velocity bolts from dense foam targets. For hunters, these bolts pair excellently with mechanical or fixed-blade broadheads. Finally, consider a sturdy hard-shell arrow case to prevent your vanes from getting crushed during transport.
Point Specifications for Excalibur Quill 16.5"
Proper weight and Front of Center (F.O.C.) are critical for the stability and accuracy of these short carbon arrows.
| Parameter | Specification |
|---|---|
| Thread | Standard 8-32 UNC |
| Diameter | 11/32" (flush fit) |
| Optimal Weight | 150 grains (minimum 125 gr) |
Point Types:
- Target: "Field Point" (150 gr) for reduced target wear and easy removal.
- Hunting: Fixed blade (e.g., Excalibur Boltcutter) or crossbow-rated mechanical heads.
Safety Tip: Total arrow weight with a 150gr point is approx. 400 grains. Avoid 100gr points, as they may cause flight instability and increase stress on the limbs.
