Molcolm got this gameplay video showing his MWS GBB converted into KAC KS-1 using the kit from Angry Gun. This is the Angry Gun KS1 MWS Conversion Kit, a high-quality upgrade for the Tokyo Marui (TM) MWS GBBR series. The kit features CNC Aluminum construction for the KS1 style upper and lower receiver, the URX6 style handguard, and the outer barrel, which includes a steel gas tube set.

It also comes with a CNC buffer tube finished in Cerakote Sniper Grey. The kit is available in two color options: classic Anodized Black or the tactical Cerakote Magpul FDE.
