Description
Laylax Nine Ball Tokyo Marui Hi-Capa Custom Lower Frame RR (5.1-inch)
This Nine Ball custom lower frame RR is made for the Tokyo Marui Hi-Capa 5.1. The lower frame is the part that carries the slide rails, trigger guard and dust cover, so replacing it is one of the biggest changes you can make to the look and feel of a Hi-Capa.
LayLax is a long-established Japanese maker of airsoft parts, with sub-brands including Prometheus for internal upgrades, Nine Ball for gas pistol parts, First Factory for external and replacement parts and Satellite for loaders and workshop accessories.
Why change the lower frame
Hi-Capa pistols are some of the most customisable gas pistols in airsoft, and the lower frame sets much of the pistol’s profile. A custom frame lets you change the look of the front of the pistol and, depending on the design, add or improve features such as an accessory rail. Please check the product images for the exact shape, finish and features of this RR version.
Nine Ball parts are made to suit Tokyo Marui’s Hi-Capa dimensions, which helps them fit well with other Tokyo Marui and Nine Ball parts.
Fitting
Fitting a lower frame means stripping the pistol substantially, including the trigger and hammer group. Work on a clean surface, take photos as you go and keep small parts in order. After reassembly, check the slide moves freely and the safety, trigger and hammer work properly before testing with gas and no BBs, then fire a few shots at a safe backstop.

Compatibility
Made for the Tokyo Marui Hi-Capa 5.1. Hi-Capa pistols from other makers, and other Hi-Capa lengths, may not fit. Spare parts are often specific to one manufacturer, and sometimes to one production version, so please compare this part with the one you are replacing, or contact us with your replica’s make and model, before ordering.
Care and maintenance
Keep the slide rails lightly lubricated with silicone oil, wipe the frame down after outdoor games and store the pistol dry with the magazine removed.
A frame swap is an involved job. If you have not stripped a Hi-Capa before, have it fitted by an experienced technician.
Who is it for?
It is for Tokyo Marui Hi-Capa 5.1 owners building a custom pistol who want to change its profile with a quality Nine Ball frame.
