QILIN BP X 28-Inch Barrel with 500CC Air Tank — Long-Range PCP Bullpup Built for Maximum Performance

The QILIN BP X 28-inch barrel version is the most powerful and long-range-focused configuration in the QILIN bullpup PCP lineup. Combining a precision 28-inch barrel with a large 500CC detachable air tank, this rifle is designed for shooters who demand higher shot capacity, improved slug performance, and enhanced long-distance accuracy.
Built through the collaboration between NorthTac and BinTac, the QILIN BP X delivers a regulated 4500 PSI PCP system, modular caliber compatibility, and advanced tuning features typically found on much more expensive air rifles.
Designed for Long-Range Accuracy
The biggest upgrade on the BP X platform is the extended 28-inch interchangeable precision-rifled barrel. Compared to shorter bullpup variants, the longer barrel improves projectile stabilization and air efficiency, especially when shooting heavy slugs at longer distances.
Despite the larger barrel and air tank, the rifle still maintains a compact bullpup configuration with an overall length of approximately 37 inches (940mm), making it significantly shorter than traditional full-length PCP rifles.
This setup provides several practical advantages:
- Better long-range accuracy
- Higher efficiency with heavy slugs
- Improved velocity consistency
- Easier maneuverability than standard rifles
- More stable shooting balance
The rifle weighs approximately 8.5 lbs (3.86kg), giving it enough mass for stable shooting while remaining manageable for field use.
Massive 500CC Air Capacity for Extended Shooting
One of the standout features of the BP X is its large-capacity 500CC detachable air cylinder. Combined with the fully regulated PCP system, the rifle delivers significantly higher shot counts than smaller PCP configurations.
The regulated system includes:
- 500CC detachable air tank
- Maximum fill pressure of 310 bar / 4500 PSI
- 60CC regulator plenum
- Adjustable regulator pressure from 70–200 bar
- External hammer spring adjustment
- Power adjustment lock system
This level of adjustability allows shooters to fine-tune the rifle for:
- Pellet shooting
- Heavy slug setups
- Hunting power
- Long-range precision
- Air efficiency optimization
The larger air reservoir especially benefits shooters who spend long sessions at the range or prefer fewer refill interruptions during hunting trips.
Serious Power Across Multiple Calibers
The QILIN BP X supports interchangeable calibers ranging from .22 to .30 caliber, with compatibility extending even further on some modular setups.
Manufacturer performance figures include:
| Caliber | Velocity | Projectile Weight |
|---|---|---|
| .22 (5.5mm) | Up to 1050 FPS | 18.13 Grain |
| .25 (6.35mm) | Around 900 FPS | 33.9 Grain |
| .30 (7.62mm) | Around 900 FPS | 50 Grain |
The long barrel and large air capacity give the BP X a major advantage when shooting heavier slugs over long distances, where consistent velocity and retained energy become critical.
According to manufacturer information, the rifle can achieve approximately:
| Caliber | Good Shot Count |
|---|---|
| .22 | Around 90 shots |
| .25 | Around 55 shots |
| .30 | Around 35 shots |
Built for Modern PCP Shooters
The QILIN BP X includes several premium-style features designed for real-world shooting performance:
- Fully shrouded barrel
- 1/2 UNF threaded muzzle
- Adjustable two-stage trigger
- Reversible forward-mounted side lever
- Full Picatinny rail system
- Interchangeable barrel and air tank system
The fully shrouded barrel helps reduce report noise, while the Picatinny rails allow easy mounting of optics, bipods, lasers, and other accessories.
The forward-mounted side lever is also designed for fast cycling and ambidextrous operation.
Real-World Community Feedback
PCP airgun enthusiasts often highlight the importance of larger air tanks for high-power rifles, especially when shooting heavier calibers or long-range slug setups. In airgun community discussions, many shooters note that 500CC systems provide a significant advantage in shot count and sustained pressure consistency compared to smaller reservoirs.
Users also commonly recommend pairing large PCP rifles like the BP X with:
- High-pressure compressors
- Carbon fiber tanks
- Dedicated fill stations
This helps maintain the rifle’s full 4500 PSI performance capability during extended shooting sessions.
Who Is the QILIN BP X Best For?
The QILIN BP X is ideal for shooters looking for:
- Maximum shot capacity
- Long-range slug shooting performance
- Heavy-caliber PCP power
- A compact bullpup hunting platform
- Advanced tuning flexibility
- Better efficiency with heavy projectiles
Compared to shorter QILIN configurations, the BP X focuses more on power, stability, and long-distance precision rather than ultra-compact portability.
Final Thoughts
The QILIN BP X 28-inch Barrel with 500CC Air Tank is designed for shooters who want the highest-performance version of the QILIN bullpup platform. Its longer barrel, larger air reservoir, regulated PCP system, and extensive tuning capability make it an excellent choice for long-range shooting, heavy slug setups, and serious hunting applications.
For PCP shooters seeking a balance of compact bullpup ergonomics and full-size rifle performance, the QILIN BP X delivers impressive capability at a highly competitive price point.
