Polymer Kit: Coverts your Foxtrot Mike, BRN-180, PSA JAKL upper receiver to a bullpup configuration.
Aluminum Kit: Converts your CMMG Dissent or Faxon ARAK-21 to a bullpup configuration.
The TRIAD Modular Bullpup Chassis is designed to house a standard Mil-spec AR receiver internally. Using a bufferless upper receiver, it converts your traditional AR into a Bullpup configuration. Please read over our detailed TRIAD INFO FAQ page for all specs and answers to all of the "how's and why's". It is important to understand the details of each configuration, as well as the legalities, before purchasing your TRIAD chassis and/or accompanying parts.
PLEASE READ BEFORE ORDERING- This kit is the main body and trigger housing only. Each brand of receiver has different requirements and will require a specific installation kit to complete your TRIAD. Compatible upper receivers are:
Foxtrot Mike FM-15
Brownells BRN-180
Palmetto State Armory JAKL
Matador Arms MAT-9
CMMG Dissent
Faxon ARAK-21
What comes in the kit and how does it work?
The TRIAD chassis ships as a partially assembled lower chassis. The front trigger and selector will already be installed, adjusted, and tested for proper operation. The customer removes the left side of the chassis and installs a bare Mil-spec AR lower receiver, trigger and bolt release (these items are NOT included). Once the linkage is adjusted to the trigger, the chassis half is re-installed and the Installation kit is then installed for your upper receiver.
What else do i need to make a complete firearm?
You will need a Mil-spec AR lower receiver, an AR bolt catch, a straight-faced AR trigger, and your choice of bufferless upper receiver along with the correct Installation kit.
