Q
Potential buyer, member, from PR, United States, asked on April 09, 2022

I got a semi Ar15, I will put a binary trigger from franklin if I can fit. Do I need a full auto BCG and this in particular can fit in my db15 pistol?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on April 27, 2022

A full auto BCG is not required for use with a Franklin Armory Binary trigger, as there is no full auto sear. However, this Bravo Company MFG Bcm Bolt Carrier Group would still fit and function as intended in your DB15.
