LS5 - ACI

The LS5-ACI is an insert that goes in a Lee Sporting LS5 Trigger Housing. It's function is to maintain compatibility between the LS5 and Atrius FRS by preventing the Atrius's lever from falling out of reach of the slip trip. It is made from a durable polyurethane in the USA. The LS5-ACI should be placed inside your LS5 Housing before the FRS. Insert the LS5-ACI in the rear of the trigger pocket. Please note, a slip trip is required to activate the Atrius FRS. We currently recommend the ALG-ACT trigger for your FRT build, it will require modification (refer to our instructions page for modification guidelines).
