ronmoss43: In the search box I typed the following: carbon express #52113=inch
Here is the link: http://carbonexpresscrossbows.com/pr...nter-crossbolt
You will see the out side diameter of the arrow as .343" If you have a digital micrometer, you can check your arrow.
To get the correct out side diameter of your required field point you need to convert the .343 to inches.
Here is the required link: http://www.agkits.com/measurement-co...on-charts.aspx
Scrolling down the chart to the .343 you will require a 11/32" outside diameter field point. This 11/32" is required no matter what weight or type of arrow point you use for that arrow shaft.
