Laylax Prometheus Straight Casing Bucking for AEG (Extra Soft - Black)
Take your rifle’s shot consistency to the next level with the Laylax Prometheus Straight Casing Bucking for AEG (Extra Soft - Black). Precision-molded in Japan, this high-performance hop-up packing features a completely flat internal profile with no built-in hop mound, making it the ideal drop-in foundation for custom Flat-Hop and R-Hop configurations. Formulated from an extra-soft, highly elastic rubber compound, it delivers maximum friction grip and airtight sealing—even in low-to-medium power setups or freezing weather conditions. Upgrade your AEG today for effortless, predictable backspin and laser-like long-range trajectory.
When aiming for maximum range and tight shot groupings, standard hop-up buckings with traditional internal mounds can introduce uneven pressure and erratic backspin. The Laylax Prometheus Straight Casing Bucking for AEG (Extra Soft - Black) solves this challenge by offering a smooth, ridge-free internal surface matrix engineered specifically for advanced Flat-Hop and R-Hop tuning setups.
Flat Internal Geometry for Extended Contact
By eliminating the molded internal mound found on traditional buckings, the "Straight Casing" design allows custom bridge nubs, flat tensioners, or R-Hop patches to apply an elongated, perfectly uniform contact area across the BB. This extended surface contact imparts a cleaner, more consistent backspin without forcing the projectile through a narrow pressure choke point. The result is significantly flatter trajectories, extended effective range, and reduced energy loss upon discharge.
Extra-Soft Compound & Cold-Weather Reliability
Molded from Laylax's ultra-compliant, extra-soft rubber formulation, this black packing conforms instantly to your inner barrel's hop window to create a 100% airtight pneumatic seal. Standard rubber compounds often stiffen, harden, and lose gripping traction in low temperatures, causing shot velocity drops and weak backspin. The Extra Soft compound remains supple and grippy even in sub-freezing environmental conditions or lower FPS builds, ensuring consistent BB feeding and reliable performance year-round.
Key Features & Technical Benefits:
-
Straight Casing (Ridge-Free) Interior: Completely smooth internal wall provides the ideal base for Flat-Hop, Bridge, or R-Hop builds.
-
Extra-Soft Rubber Compound: Delivers exceptional friction grip, maximal compliance, and cold-weather flexibility.
-
Airtight Compression Seal: Prevents pneumatic blow-by around the feeding lips to stabilize muzzle velocity (FPS).
-
Universal AEG Compatibility: Matches TM-spec M4, AK, MP5, G36, and V2/V3 AEG hop-up chamber geometries.
-
Precision Japanese Manufacture: Built to strict tolerances to eliminate feeding jams and prevent premature rubber tearing.
Installation & Field Guidance
This bucking is designed specifically for use with aftermarket flat tensioners (such as the Prometheus Hop Tensioner Bridge Type) or R-Hop patches and does not feature an internal mound. Before installation, lightly clean the outer surface with isopropyl alcohol. Ensure the inner barrel window is completely free of sharp burrs before sliding the packing into place. Apply a microscopic film of silicone oil only to the exterior surface of the bucking to assist smooth insertion into tight CNC aluminum hop-up chambers.
Note: This is a flat bucking with no internal mound. It is designed to be used in conjunction with a flat tensioner (sold separately).
