If you decide to use standard nocks get ones that fit better. If the pic is correct the nock looks to big for shaft. You should see a very slight line of bare shaft when you put nock on. Also feel the shaft and see if it is tapered at the nock end. Later versions of the AO are like this. If size is like 2114 or 2117 with the taper I use 5/16 nocks.
If you decide to cut and use the push in nocks you should call and talk to them and make sure the inserts fit your shafts. With carbon being the most sold shafts now the alum shaft supplies has narrowed in scope.
