The DISSENT – Will it FRT?

Published on May 19, 2025
Duration: 5:38

This video from CMMG explains why their Dissent firearm platform is not compatible with most FRT (Forced Reset Trigger) or binary-style triggers. The primary reason is the Dissent's compact bolt carrier group, which lacks the necessary rearward mass and cut for sear engagement required by these advanced trigger systems. Standard AR-15 drop-in triggers are generally compatible, with the exception of the BR series. CMMG also details a sear trip accessory for their .22LR conversion kits designed for registered full-auto lowers, but cautions that compatibility with aftermarket binary triggers is not guaranteed due to varying geometries.

Quick Summary

The CMMG Dissent firearm is incompatible with most FRT (Forced Reset Trigger) and binary-style triggers because its compact bolt carrier group lacks the necessary rearward mass and specific cut for sear engagement, a critical component for these advanced trigger systems.

Frequently Asked Questions

Why are FRT or binary triggers not compatible with the CMMG Dissent?

The CMMG Dissent features a compact bolt carrier group that lacks the necessary rearward mass and specific cut required for sear engagement, which is essential for most FRT and binary-style triggers to function correctly.

What type of triggers are generally compatible with CMMG firearms like the Dissent?

CMMG firearms are typically designed to work with standard drop-in AR trigger control groups. The primary exceptions are the BR series firearms and certain FRT or binary style triggers due to their unique engagement mechanisms.

Can I use a CMMG .22LR conversion kit with an FRT or binary trigger?

While CMMG offers a sear trip accessory for their .22LR kits for use in registered full-auto lowers, compatibility with aftermarket FRT or binary triggers is not guaranteed. You may need to make minor adjustments to the sear tab due to varying trigger geometries.

What is the key difference between an M16 carrier and an AR-15 carrier regarding triggers?

An M16 carrier group has a specific cut further forward to engage with an auto sear for full-automatic fire. An AR-15 carrier group's cut is typically farther back, preventing proper sear engagement needed for many advanced trigger systems like FRTs.
