The base TRIAD chassis is compatible with the BRN-180, Foxtrot Mikes, and JAK'L upper receivers however there are differences with each upper that require some specific components. For instance, the Foxtrot Mikes upper and the JAK'L upper require completely different buffers to function correctly, so we have specific buffers for each kit. Additionally, the BRN-180 has a smaller diameter handguard than the Foxtrot Mikes uppers, so the forward takedown lug and triggger housing cap have to change to accommodate those differences.
When you purchase your TRIAD chassis, we include everything for the specific upper you choose, however, if you want to run different uppers with the same TRIAD chassis, these are the conversion kits necessary to update your chassis for that upper.
