Jaeger Precision reviews the RGW M-Lok rail set for the Guns Modify Scar-L MWS GBBR, detailing its installation, which includes a lower piece and M-Lok panels, but highlights significant drawbacks such as fitment and color matching issues, and critically, the incompatibility of standard M-Lok accessories on the side rails; despite improving handling comfort, the rail kit's functionality is ultimately deemed poor due to these machining and compatibility problems.

The Heresy Group shows the SCAR-L M-Lok Kit made by Airsoft Artisan which is based in Hong Kong. Installation is not a problem as Tim also does a step-by-step procedure on installing it on the Tokyo Marui SCAR-L NGRS AEG which can be done in 15 to 20 minutes. If you dig it, then you can get one for 30 quid.
