Sorry for the answer, I have not returned a ACOG for relit. I did with a Armson OEG, total screw up. Was trading for a ACOG and I wanted to know the cost if the tritium was bad. Was good.
Several years ago it cost me $229.00 with law enforcement discount! I looked back and can’t find my contact information for them. I may have it in shop. If I locate it I’ll send it to you! They did excellent job and works perfectly.
