couple exterior build in mind, however some parts are avaliable some parts are not
SPR build : the Magpul PRS butt stock is avaliable, the long hand guard (circled) is not
Standard rifle / carbine build : the circled standard ACR but stock is not available
Enhanced rifle / carbine build : only build with all parts avaliable which is the stock that came with the J10, and the 3 sided short metal rail… but tbh not a big fan of that short metal rail
has anyone seen either one of those circled part avaliable for J10 anywhere?
