Description

Full-Size Kabuto Drop-In Rapid Reset System (PLA+ Housing)

Built for high-performance operation, the full-size Kabuto is a drop-in Rapid Reset System designed specifically for the AR-15 platform. Delivering incredible speed and reliability, every unit features precision components and arrives ready to install.

Heavy-Duty Materials & Construction

• Robust Housing: 3D printed from durable PLA+ for a rigid, dependable structure.

• Precision Internals: Built with 304 stainless steel internals paired with a rugged tool steel pin for maximum wear resistance and longevity.

• Reinforced Ambidextrous Safety: Ships complete with a 3-position selector switch. Like your other builds, this features the redesigned safety uniquely internally reinforced with a full-length stainless steel screw running through its core to eliminate the high-stress failure points common in standard printed safeties.

Performance & Buffer Tuning Note

Because this system cycles at an extremely high rate of speed, buffer weight selection is critical for reliable performance:

• Some setups will run fine on a standard carbine buffer.

• However, because it can cycle fast enough to outrun standard setups and cause jams, we strongly recommend using an H1, H2, or H3 buffer to tune the bolt speed.

• Note: Never use a solid (rifle-style) buffer.

Compatibility & Requirements

• Platform: AR-15 (Fits most mil-spec lowers with a standard mil-spec fire control group that requires zero modification). Successfully tested on popular builds including PSA, Aero Precision, Anderson, Daniel Defense, Core15, and DPMS.

• Bolt Carrier Group: Requires an M16 bolt carrier group (BCG) to function correctly.

• Exclusions: Will not work in CMMG .22lr setups (due to different lever geometry). Only mil-spec triggers are fully confirmed at this time; other trigger types are untested.
