Laylax (Nine Ball) Tokyo Marui Hi-Capa Custom Lower Frame RR (5.1-inch)
Transform your sidearm's ergonomics, weight distribution, and accessory capability with the Laylax (Nine Ball) Tokyo Marui Hi-Capa Custom Lower Frame RR (5.1-inch). Precision-crafted in Japan from die-cast aluminum alloy, this custom middle frame drops the weight by approximately 58% compared to standard factory metal frames—weighing in at a featherlight 61g. Featuring a built-in, slim Picatinny under-rail, it allows seamless attachment of weapon lights and lasers while maintaining a sleek profile. Upgrade your 5.1 or Gold Match build today for faster target handling and crisp cycle balance.
The Tokyo Marui Hi-Capa 5.1 is the cornerstone of custom airsoft handguns, but optimizing your build for speed and modern accessory mounting requires replacing heavy stock cast components. The Laylax (Nine Ball) Tokyo Marui Hi-Capa Custom Lower Frame "RR" (5.1-inch) provides a high-performance structural chassis designed to enhance agility, weight balance, and tactical versatility.
Lightweight Aluminum Construction & 58% Weight Reduction
Engineered specifically for high-speed competition shooters and tactical operators, this custom lower frame is die-cast from a high-grade aluminum alloy. Weighing only 61 grams, it slashes lower chassis weight by roughly 58% over original factory frames. This drastic reduction in frame mass decreases total gun inertia, enabling lightning-fast target-to-target transitions and reducing wrist fatigue during prolonged tournament play.
Integrated Slim Picatinny Under-Rail
Unlike traditional frame setups that require bolt-on rail adapters or bulky add-ons, the "RR" frame features an integrated, continuous slim Picatinny rail directly beneath the dust cover. This sleek profile preserves holster compatibility while giving you a rock-solid mounting platform for weapon-mounted tactical flashlights, lasers, and rail accessories.
Key Features & Technical Benefits:
-
58% Weight Reduction: Weighs only 61g to maximize speed and lower gun inertia.
-
Integrated Under-Rail: Continuous slim Picatinny rail for direct mounting of lights and lasers.
-
Die-Cast Aluminum Alloy: Delivers high structural rigidity and durable slide-rail alignment.
-
Balanced 5.1 Geometry: Custom-molded to match standard 5.1-length slides perfectly.
-
Made in Japan Quality: Precision-machined by Laylax (Nine Ball) for reliable drop-in fitment.
Installation & Field Guidance
This lower frame is a direct drop-in replacement for the Tokyo Marui Hi-Capa 5.1 and Hi-Capa 5.1 Gold Match GBB pistol series (Note: Not compatible with Hi-Capa D.O.R. series). Installation requires intermediate technical knowledge to transfer the internal valve knocker, sear spring, hammer housing assembly, and front chassis blocks into the new frame. Apply a light coat of synthetic grease along the upper slide rails prior to reassembly to ensure silky-smooth, low-friction slide action.
