InformationEdit
CN: 牛犊式布局的突击步枪安装配件经常面临导轨不足的困境，多亏了KTC原厂推出的3英寸四导轨护木，战术圣诞树再也不是传统布局枪支的专属了，RFB专用。
EN: Insuficcient space is often a problem when mounting accessories onto bullpup assault rifles. Thanks to this three-inch quad rail produced by the original manufacturer KTC, the tactical Christmas tree is no longer dominated by standard firearms. Can only be equipped by Am RFB.
Obtained as an event shop item from the Christmas seasonal event A Snowy Nights Capriccio for 
x80. Max 1 purchase.
Minimum Level Required: 60
