Questions & Answers
will this bcg operate with a franklin binary trigger? Expert Answer

Yes. The ODIN Works LOW Mass 223 Nitride Bolt Carrier Group will fit AR15 platform rifles in 5.56/.223 and 300 Blackout. It will function as intended with a binary trigger. Tuning via the buffer system or with an adjustable gas block may be required due to the lighter weight.
