1913 Alu. shaft?

[Stone Knife]

Is there 1913 alum. shafts still available that are swaged to take a classic nock, or do they make a nock for the for the uni bushing that would be comparable, I don't want the nock too tight.

I don't think they are still being made with a swaged nock end.You would have to find some NOS.The uni-bushing Easton makes for 1816,1913 and 1916 is called a X-bushing that will accept a X-nock.Same nock that is used for Axis/MFX.Bohning's verison is called an A-nock.The Bohning A-nock has a slightly larger throat then a Easton X-nock.I think they also make a G-bushing for them also,then you can use a large groove G-nock with a .098 throat.
