ARCHERY GUIDE: ARROW MASS & FOC CALCULATOR

ARROW SIMULATOR

Before you actually order your custom arrows, use this calculator to build a simulated set of arrows - so you'll know what total mass and FOC balance your choices will yield. Please note: manufacturer GPI data tends to be rounded to the nearest tenth of a grain. We've built in some small margins to account for rounding and the mass of adhesives. So our simulator is going to be very very close. But please don't hold our feet to the grain here ...

ARROW MASS:

 

FOC:

 

Point Weight in Grains: HELP: Enter the weight of your arrow tip. Common tip weights are 75, 85, 90, 100, 110, and 125, with 100 grain tips being the typical choice.
Insert Type: HELP: Choose your type of arrow insert. See manufacturer data for standard and optional insert types - particularly with Easton/Beman.
Nock Adapter: THIS IS NOT COMMON: Some nocks require collars or adapters so that specialty nocks can be used such as Pin Nocks. If none, select "None."
Nock Type: HELP: Choose the type of nock installed in your arrow (S, X, H, Pin, Lumenocks, etc.). Do not include optional nock weight here.
Added Nock Weight: THIS IS NOT COMMON: Some nocks can be fitted with additional weights to add mass and decrease FOC. If none, leave at 0.
Arrow Shaft: HELP: Choose the brand, model, and size of your arrow shafts. If your arrow shafts is not included here, choose a shaft with the same g.p.i.
Shaft Length: HELP: Note that the shaft length isn't the same as arrow length. The shaft length will be 1/4-1/2" LESS than your finished AMO arrow length.
Fletching Type: HELP: Select the type of fletching you prefer to use. Data is based on Gateway feathers and Duravane brand plastic vanes.
Number of Fletches: 3 FLETCH IS COMMON: A 4-fletch arrow is very uncommon. For the vast majority of applications, this value will be 3.

NOTE: Most carbon arrow manufacturers recommend an F.O.C. balance between 7% and 15%.
