I got some Classic 500. Can you weight them the same as you can Gold tip
I am not sure if they are the exact same ID, but I am using the 3rivers brass inserts on Beman ICS 500 shafts and they work fine.
The Beman ICS Classic's take the same size nocks and inserts as Gold Tip's do.If you have Beman MFX Classic's they take the HIT inserts and nocks same as Axis.
