We’ve provided several answers to questions related to Waldo Dynamics Crimson NPAS for VFC / APFG / Maruyama , see some other helpful Q&A related to this product.
Question: Will this fit my specific VFC/APFG/Maruyama GBBR?
Answer: It's compatible with a wide range of VFC, APFG, and Maruyama GBBR platforms. Check the full compatibility list above before ordering, since not every GBBR variant is covered.
Question: Is there a risk of over-adjusting it?
Answer: Yes, like any NPAS, don't fully unscrew the adjustment xxxx or you risk losing the seal entirely. Make small adjustments and test after each one rather than cranking it to an extreme in one go.
Question: What makes the Crimson NPAS different from other NPAS units on the market?
Answer: Its internal bore is tighter than most, specifically tuned for the 0.9–1.2 joule range where many fields set their limits.
Question: Do I need to fully disassemble my GBBR to adjust it?
Answer: No, just remove the bolt, adjust through the front of the nozzle, then reassemble. No full teardown needed, though installing the NPAS for the first time does call for some GBBR teching knowledge and basic tools.
Question: What tools do I need to adjust it?
Answer: Just a 1.5mm hex key, included in most standard hex key sets. Turn clockwise for less power, counter-clockwise for more.
