TRIAD Bullpup Chassis - Aluminum

CONVERT your CMMG DISSENT or FAXON ARAK UPPER RECEIVER 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. This page lists all specs, and answers 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 work with your TRIAD. Compatible upper receivers are:

FAXON ARAK
CMMG DISSENT

NOTE: this version of the TRIAD is not compatible with the Foxtrot Mike FM-15, Palmetto State JAKL, Matador Arms MAT-9, or Brownell's BRN-180.

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 rear part 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 TRIAD FIREARM? You will need a Mil-spec AR lower receiver, an AR bolt catch, a straight-faced AR trigger, your choice of bufferless upper receiver listed above, and the appropriate Installation kit.
