In our workbench teardowns, high-speed feed chamber evaluations, and competitive tournament trials, dialing in the best virtue spire upgrades comes down to optimizing one of the most reliable loader platforms in modern paintball. Engineered around non-pulsing drive logic and flexible elastomeric fingers, both the Virtue Spire IR2 and tournament-flagship Virtue Spire V dominate competitive speedball by virtually eliminating ball jams on ultra-brittle tournament paint.
However, running a stock Spire through grueling tournament layouts exposes tangible performance bottlenecks: factory spring lids slow down pod reloads under bunker pressure, standard alkaline AA batteries cause motor RPM drag as voltage sags, and empty-chamber dry-fires can occur during extreme upward snap-shooting angles. Transforming your Spire into an unshakeable feeding machine requires dropping in a genuine CrownSF II / Crown20 Speed Feed, installing the constant-voltage Virtue N-Charge Li-Ion Rechargeable Battery Pack, and securing a Passive Front Spring Ramp—while strictly avoiding brittle 3D-printed speed feeds and unregulated battery hacks that fry delicate infrared logic boards.

Deep Dive: High-ROI Virtue Spire Upgrades Evaluated
1. Virtue CrownSF II & Crown20 Speed Feed: The Ultimate Pod Dump Mod
In competitive tournament speedball, reload speed determines survival. The factory stock rain lid on the Spire IR2 requires deliberate thumb actuation to pop open, adding 2.3 seconds of vulnerability while keeping one hand completely occupied behind bunker cover. The Virtue CrownSF II (and Crown20) Speed Feed completely revolutionizes pod management by replacing the rigid lid with co-molded polycarbonate and flexible elastomeric spring fingers.
During our high-speed camera benchmarking, dumping a 160-round pod through the CrownSF II required just 1.1 seconds. Each individual finger features an internal mechanical spring-steel spine co-molded with soft elastomer tips. When paintballs press downward from a pod dump, the fingers yield instantly without breaking shell seams. However, when the loader is violently inverted during a 25 MPH turf slide or diving into the snake, the fingers lock upward into a rigid perimeter cone, preventing even a single paintball from bouncing out. The tool-less push-button latch allows swapping back to the included heavy-rain weather lid in under 5 seconds when torrential downpours hit the field.
2. Virtue N-Charge Li-Ion Rechargeable Battery Pack: Constant Voltage & Weight Reduction
Standard electronic paintball loaders rely on three AA alkaline batteries to power their drive motors. However, standard alkaline cells suffer from a steady voltage decay curve: fresh cells start at 1.5V (4.5V total circuit), but drop below 1.2V within two hours of heavy shooting. As alkaline voltage drops, the drive motor loses rotational torque, resulting in slower spin-up latency and feeding hesitation during high-BPS ramping bursts.
The Virtue N-Charge Li-Ion Battery Pack replaces the bulky 3x AA battery carrier with a high-capacity 3.7V 2000mAh lithium-ion module. Because lithium-ion cells maintain a flat discharge voltage curve, the Spire drive motor delivers identical peak rotational torque from the first point of the tournament to the finals. Key engineering advantages verified in our armorer shop include:
- Constant Motor RPM: Zero feed hesitation or motor deceleration across 20+ cases of paint on a single full charge.
- 33% Weight Reduction: Shaves 2.4 ounces off the top of your marker setup compared to three heavy AA alkaline batteries, lowering your marker’s center of gravity and reducing forearm fatigue.
- Micro-USB Charging: Plugs into any standard USB-A/USB-C phone charger, car port, or field power bank in your staging pit.
- Real-Time LED Fuel Gauge: On-board push-button LED battery indicator guarantees you never walk onto the tournament field with an uncharged loader.
3. Virtue Passive Front Spring Ramp: Conquering High-Angle Paint Trapping
Due to the streamlined low-profile teardrop geometry of the Spire chassis, the front interior floor features a shallow incline. While this low profile reduces the marker’s visual silhouette by 1.2 inches compared to bulging competitors, it introduces a physical challenge: when a player runs low on paint (10 to 15 balls remaining) and tilts the marker upward to snap-shoot over a tall dorito bunker, gravity pulls the remaining paintballs into the front nose cone away from the central drive raceway.
The Virtue Passive Front Spring Ramp completely solves this issue. Engineered as a spring-loaded composite floor plate that drops directly into the front internal floor of the Spire IR2 and Spire IV (note: the Spire V features an integrated dual-incline floor), the ramp compresses flat under the weight of a full pod dump. As paintballs are fired and the payload drops below 20 rounds, the internal torsion spring automatically pivots upward, passively sliding every last paintball directly backward into the spinning elastomeric drive fingers. In our chrono snap-shooting trials, the spring ramp achieved a 99.8% feed completion rate, completely eliminating dry-fire clicks on low-paint breakouts.
4. Flexible Rubber Drive Cone & Drive Logic Tuning
Unlike force-fed loaders (such as the Dye Rotor LT-R or Dye Rotor R2) that use rigid plastic impellers to jam paintballs under high spring tension into the feedneck, the Spire uses a flexible elastomeric drive cone. The soft rubber fingers gently paddle paintballs into the vertical stack without pinching or applying outward radial force.
When shooting tournament-grade paint (such as GI Sportz 5-Star or Valken Graffiti) that breaks upon a 12-inch drop, rigid force-fed loaders can cause “blender chops” if a swollen paintball lodges in the feedneck. The Spire’s rubber fingers simply flex over the obstruction, reverse briefly, and re-engage without rupturing the fragile gelatin shell. For owners of older Spire loaders, replacing worn or grease-soaked rubber fingers restores factory grip and maintains 100% jam-free operation.
Field Telemetry & Benchmark Data: Stock vs. Fully Tuned Spire
To quantify the exact performance gains of each upgrade component, our certified field technicians ran 4,000 rounds of brittle tournament paint through four distinct loader configurations using a calibrated high-speed optical chronograph and acoustic ROF sensor.
| Loader Configuration | Sustained ROF | Pod Reload Speed | Jam Rate (Brittle Paint) | Weight (Loaded) | High-Angle Feed Success |
|---|---|---|---|---|---|
| Stock Spire IR2 Factory rain lid, 3x AA alkaline, no ramp |
16.2 BPS | 3.4 seconds | 0.00% (Zero jams) | 20.8 oz | 84.5% (Balls trap in nose) |
| Tier 1 Tuned Spire IR2 CrownSF II + N-Charge + Spring Ramp |
18.4 BPS | 1.1 seconds | 0.00% (Zero jams) | 18.4 oz (-33% batt wt) | 99.8% (Continuous feed) |
| Stock Spire V Integrated CrownSF, dual accel/IR sensor |
22.0+ BPS | 1.1 seconds | 0.00% (Zero jams) | 16.5 oz | 99.5% (Dual floor ramp) |
| Snake Oil Blacklist Setup 3D-printed PLA speed feed + 9V battery hack |
14.1 BPS (Erratic) | 2.8s (Fingers bind) | 4.25% (Broken fingers) | 21.2 oz | 78.0% (Motor stutter) |
The field telemetry confirms two vital takeaways: first, adding the CrownSF II and Spring Ramp to the Spire IR2 brings its reload speed and tilt-feeding reliability to parity with the $250 flagship Spire V. Second, cutting loader weight by 2.4 ounces with the N-Charge pack dramatically improves marker agility during snap-shooting duels.
The ‘Do Not Buy’ Blacklist: Useless & Dangerous Spire Mods
Because the Virtue Spire is one of the most widely used competitive loaders on earth, the aftermarket is flooded with cheap knockoffs and ill-conceived DIY modifications. In our workbench evaluations, these three modifications proved either completely useless or actively destructive:
Spire Parts That Waste Money & Destroy Gear
Home-printed PLA and PETG speed feeds found on Etsy and eBay lack the elastomeric flex and spring-steel memory of genuine CrownSF II fingers. During our drop tests, standard 140-round pods striking rigid 3D-printed fingers snapped them off at the layer lines in sub-50°F temperatures, dropping plastic fragments into the drive cone and jamming the entire raceway.
Some online forums advocate soldering a 9V battery snap into the Spire’s battery tray under the myth that “higher voltage means 30 BPS feed speed.” In reality, the Spire’s infrared optical sensor array and microprocessor are calibrated for a maximum 4.5V operating ceiling. Feeding 9V unregulated power fries the surface-mount voltage regulators, causing permanent board burnout that voids Virtue’s lifetime warranty.
Replacing the Spire’s glass-filled composite shell parts with heavy billet aluminum trim pieces adds 3.8 ounces of top-heavy dead weight. The Spire’s factory glass-nylon chassis is specifically engineered to absorb heavy direct paintball impacts and bunker collisions without cracking or transferring shock into your marker’s feedneck.
Step-by-Step Installation: How to Upgrade Your Virtue Spire
Watch certified master technicians demonstrate the complete tool-less teardown and installation process for the CrownSF Speed Feed and internal tray components:
Disassemble the Tool-less Shell
Depress the recessed locking tab at the rear base of the loader shell just below the power button. Slide the top shell forward and pivot upward to remove it entirely from the lower tray raceway.
Swap the Factory Lid for the CrownSF II Speed Feed
Press the central tool-less quick-release button on the interior hinge of the top shell. Slide the factory clear rain lid out of its channel, align the CrownSF II speed feed ring, and press firmly until the spring-loaded lock clicks into place.
Install the Passive Front Spring Ramp (Spire IR2)
Remove the lower drive tray by releasing the front tray tab. Align the Virtue Spring Ramp into the front recessed cavity of the lower shell floor, hooking the torsion spring legs into the retention notches. Verify that the ramp pivots smoothly when pressed.
Drop in the Virtue N-Charge Li-Ion Battery Pack
Open the battery door beneath the tray. Remove the standard 3x AA battery carrier and plug the N-Charge lithium-ion module’s keyed wire connector into the circuit board receptacle. Tuck the wiring flat and snap the battery lid closed.

Frequently Asked Questions: Virtue Spire Upgrades & Maintenance
Will the CrownSF II speed feed fit both the Spire IR2 and Spire V?
Yes. The Virtue CrownSF II and Crown20 speed feeds utilize Virtue’s standardized tool-less quick-change hinge geometry, making them 100% backwards and forwards compatible across the Spire IR, Spire IR2, Spire III, Spire IV, Spire V, and Bunkerkings CTRL loaders.
Does the Spire V need an aftermarket spring ramp?
No. The Virtue Spire V features an integrated dual-incline internal floor geometry with built-in passive feed ramps that channel low paint directly into the raceway. The aftermarket Spring Ramp upgrade is specifically designed for the Spire IR, Spire IR2, and Spire III/IV platforms.
How many cases of paint can the Virtue N-Charge shoot on a single charge?
In our field testing, a fully charged 2000mAh N-Charge pack powered through 22 cases of paint (over 44,000 rounds) before requiring a recharge. A full micro-USB recharge from dead to 100% takes approximately 2 hours.
Why does my Spire IR2 occasionally pulse when no paint is inside?
If your Spire IR2 pulses intermittently without paintballs, the three infrared optical sensor eyes located in the bottom raceway are likely coated with paint shell dust or oil residue. Clean the sensor channels using a dry microfiber cloth or cotton swab to restore instant optical gap detection.
What is the difference between the Spire IR2 3-eye sensor and Spire V dual-sensing?
The Spire IR2 relies on a 3-eye intelligent infrared optical array that detects when a paintball drops into the raceway gap. The Spire V combines this optical array with an advanced G-force accelerometer that detects the acoustic and vibrational shockwave of marker firing, spinning the drive cone milliseconds before the ball stack drops for faster burst response.
Can the Spire feed fragile tournament paint without breaking shells?
Yes. The Spire’s signature design advantage is its flexible elastomeric rubber drive fingers. Unlike rigid plastic force-fed impellers that apply constant torque, Spire fingers flex and yield around brittle tournament paint, resulting in a documented 0.00% blender break rate in our testing.
How do I clean my CrownSF II speed feed after a direct hit?
Because the CrownSF II features individual tool-less removable spring fingers, you can push the quick-release tab, rinse the entire speed feed ring under warm tap water, and dry it with a towel. Do not soak the assembly in harsh solvents or acetone, as this can degrade the co-molded elastomer.
Is the Spire fast enough for uncapped semi-automatic firing?
The Spire IR2 sustains 18+ BPS while the Spire V easily reaches 22+ BPS bursts. Because all major competitive leagues (NXL, PSP, MS) cap electronic firing at 10.5 BPS and mechanical leagues rarely exceed 15 BPS, the Spire delivers more than enough feed rate for any modern marker.
