The Accipiter line exists for shooters who need the absolute best performance-to-weight ratio we can deliver. There's a saying in engineering: the last 5% takes as much work as the first 95%. The Accipiter line is that last 5%. These are not fundamentally different moderators from our Falx and Sarissa; they use the same proven gas diode and damping architecture. What's different is that every single element has been reanalyzed and pushed as far as it can go in the direction of reduced weight and improved acoustic performance. The result is a moderator that's over a third lighter than its standard counterpart while improving on its acoustic performance. That doesn't come free; the Accipiter line requires substantially more effort to manufacture and is priced accordingly.

Two body sizes are available, corresponding to the Falx and Sarissa dimensional envelopes. The bodies themselves are visually distinct from the standard line: the aluminum tube is thinner-walled than its standard counterpart, and each Accipiter carries our falling feather logo engraved on the side. Weights by configuration:

• Falx-size, Standard Flow: 115 grams

• Falx-size, Moderate Flow: 107 grams

• Sarissa-size, Standard Flow: 172 grams

• Sarissa-size, Moderate Flow: 155 grams

The design uses Nikola Tesla's Gas Diode to reflex propellant air back on itself, resisting forward flow through geometry alone with no moving parts. This three-stage approach first strips air off the pellet to reduce turbulence and improve accuracy, then delays it through compound gas diode stages, and finally passes it through a high-performance damping section to absorb residual sound energy. The design adapts along its length rather than repeating a single approach end to end, applying the right technique at the right point in the air's journey through the moderator.

The anodized aluminum tube is serviceable and modular. Cores can be swapped as the technology advances, meaning an Accipiter purchased today can be upgraded rather than replaced as new revisions become available. All designs are considered experimental.

Key Features:

• Tesla Gas Diode design: Compound diode stages reflex and delay propellant air through geometry alone, no moving parts

• Adaptive staged architecture: Design transitions along its length to maximize attenuation at each point in the air's travel

• Tapered bore: Improves sound attenuation while reducing the likelihood of pellet clipping

• Ultra-light composite cores: New composite material cuts core mass by more than 50% compared to the standard line without sacrificing acoustic performance

• Thinned aluminum tube: Lighter wall thickness reduces overall weight while maintaining the serviceable modular architecture of the standard line

• Flow factor variants: Standard and Moderate flow cores available

• Falling feather engraving: Exclusive to the Accipiter line

• Built and tested in the USA
