A-Serts are patented adjustable inserts for precision broadhead tuning.  A-Serts easily index your broadhead to your arrow vanes insuring a smoother arrow flight.  A-Serts work all the time, every time, with most styles of arrow tips.  A-Serts are intended for carbon arrows and crossbow bolts that use removable nocks.  Webb Products has a weight-forward system for A-Serts that easily allows you to add or remove weight.  Try A-Serts, you will wonder what you ever did without them!




A-Serts are machined with the highest tolerance possible.  Add the A-Sert patented rotational adjustment feature for fast broadhead tuning; and you now have the straightest, most accurate inserts in the industry.  If you want to shoot a precision arrow, then shoot a precision insert!




The A-Sert Adjusting Tool lifetime warranty is simple. If it becomes damaged, send it back to us for a new replacement.
