Will this work in an extar ep9???? Or would u recommend the Franklin binary trigger?

Expert Answer

Answered by Armando R., Gear Expert, from IL, United States, on March 18, 2020

We cannot recommend any of the binary triggers systems for the Extar EP9. Both units use an AR bolt carrier and Franklin specifically states no polymer lowers for their trigger. My best recommendation would be to contact Extar directly to verify whether they recommend any of the binary triggers because compatibility information for anything that is not a standard AR lower receiver is lacking.

Will this work on a colt 9mm AR lower?

Yes, the Fostech Echo Sport AR-15 Trigger will be compatible with your Colt AR9 lower receiver. However, if you have a 90's era Colt, you would need to use a trigger that comes with large trigger pins.
