"No 80% lowers, polymer lowers or carbon lowers.", is it saying this trigger won't work on polymer lowers? And what's an 80% lower?

Manufacturer Answer

Answered by Franklin Armory, Manufacturer from NV, United States, on August 22, 2019

We have found that many 80%, carbon fiber, and polymer receivers are not within Milspec tolerances. Lower receiver must be within Milspec for our trigger to operate.

Will this work in conjunction with the BRN-180s? If not, is there anything that does?

Expert Answer

Answered by Armando R., Gear Expert, from IL, United States, on February 19, 2020

This will not function with a BRN-180S and I am not aware of a binary trigger system that will because of how the firearm functions.

Will this work in a S&W 15-22

Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on March 16, 2022

The OpticsPlanet Exclusive Franklin Armory BFSIII AR-C1 Trigger is not compatible with polymer frame AR's. So it will not work in a Smith and Wesson M&P15 22.

do I need a full auto bcg for this trigger to work?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on December 13, 2023

While Franklin Armory states their BFSIII AR-C1 Trigger is compatible with most BCG's, it is recommended to use a full-auto BCG as they reduce "bolt-bounce" as they are heavier. However, you can still use a non full-auto BCG and it will function as intended.

Allen, member, from OH, United States, asked on May 28, 2018

Will this work in a Sig Sauer MCX Rattler 300 blackout pistol?

Manufacturer Answer

Answered by Franklin Armory, Manufacturer from NV, United States, on August 22, 2019

The MCX and MPX series of firearms are not made to Milspec tolerances. Because of this the Franklin Armory trigger may or may not function in one of these platforms. It depends entirely on your individual firearm. Lowers must be within Milspec tolerances for the trigger to operate.
