So first thing first ill show you the inserts I put together for them. I got a hold of some CX Edge rustproof stainless steel half in half out inserts. These are 17/64" and they fit the Axis arrows perfectly and they weigh about 43 grains. I then cut the threaded part off of some field points, fanned some super glue on one end and screwed them halfway into the back of the insert leaving about three threads exposed. I took the 75 grain brass break off hit inserts and broke the back off making them 50 grains. I then mixed up some hit epoxy and dipped the threads I installed on the back of the CX Edge Insert and screwed them onto the back of the CX Edge inserts. This makes a 100 grain half out stainless steel insert for your Axis arrows. But by not breaking off the insert or using the 100 grain hit inserts you can make a 125 or 150 grain insert as well. Super strong, strengthens the arrow, no need to foot. Here's some pics to show what I described. Hope this helps some of you guys.
