Like said it is easy,just cut the taper off and glue in some uni-bushings and any of the push-in nocks with a .246 OD will work.I have done this to 2016 and 2018 Legacys,I like Easton 3D Super nocks.They fit my strings the best.You can also do this for 1916's,Easton has a X-bushing for them that will use an X-nock,the same nock used in Axis/MFX. I just cut off the taper and scuffed and cleaned the inside with alcohol.I used the same two-part epoxy I use for gluing inserts in my carbon arrows.Just don't use excessive epoxy so it won't block the nock from pressing in.
