Yes, if the upgrade is consistent .

The main problem with custom AAPs is internal imbalance (too much gas, too hard hammer, too fast cycle).

👉 At BDU-Airsoft, each build is mechanically balanced : valve, nozzle, hammer, springs and bolt are chosen to work together, not just to “better than stock”.

• Premature wear of the hammer/sear
  
• Bolt breakage or crack
  
• Inconsistent FPS (poorly controlled gas)
  
• Random feeding with some chargers
  
• Hop-up becomes unstable after a few magazines
  

👉 These problems often come from upgrades not tested together or fitted without adjustment.

Yes, but not without validation .

Some combinations work perfectly, others create:

• internal friction,
  
• an excessively violent cycle
  
• or a tolerance/tolerance incompatibility.
  

👉 Our builds are made with proven configurations , tested in the workshop before delivery.

A properly assembled AAP-01 can achieve:

• a responsiveness close to that of an HPA (High Pressure Area) ,
  
• excellent FPS consistency
  
• range and accuracy comparable to some compact rifles.
  

👉 The limit is not the platform, but the quality of the editing and settings .

Not necessarily.

An optimized AAP often consumes less energy than a stock AAP because:

• The cycle is smoother.
  
• The leaks have been fixed.
  
• The valve is better utilized.
  

👉 Poor optimization = overconsumption.

👉 Good optimization = improved performance.

Absolutely.

We design our custom products to be scalable :

• Internal upgrade today.
  
• HPA or aesthetics later
  
• Targeted optimization based on your play style.
  

👉 We avoid “disposable” upgrades.

Yes, and it's actually one of our strengths.

Some of our builds are intentionally: simple, lightweight, focused on pure efficiency.

👉 Style is optional, performance is not.
