Introduction
Aftershock Archery introduces a small accessory
that should not miss from your toolbox: The
Booster
What is it?
It’ s an aluminum collar made from 7075 High
Grade aluminum, anodized in green and machined
to precise tolerances. It fits between your
arrow point (either field or broadhead) and the
insert, as it is threaded on both sides. It adds
precisely 25 grains to your setup: on 6 samples
we measured a deviation from nominal weight of
+-0.1 grains. The
Booster is manufactured in two variations:
Boo-25 and Boo25xb. The difference is that the
XB is conical tapering from .315 to.350 and it
is finished in lighter shade of green. The
Boo-25xb is advertised as “crossbow specific”
however there is nothing really specific to
crossbows as most crossbows use a rather large
22/64” (.343”) arrow shafts and points thus the
tapering is not really needed unless you want to
use points smaller than the shaft diameter
(???).
Who will need it?
Everyone who needs to increase its arrow weight
in a quick and clean manner without going
through the procedure of replacing inserts in
order to give your arrows more “punch”. The
Booster collar will also help moving the FOC
balance forward. Another situation the Booster
comes handy is when your field point weight does
not match the broadhead weight: some
manufacturers introduced crossbow specific
broadhead in a heavy configuration (170 grains)
but field points of this weight are not commonly
found.
Usage
The booster is pretty straightforward to use,
unscrew your point, screw in the Booster, and
now screw the point into the Booster: done! Your
arrow is now 25 grains heavier for some more
“punch”.
As we tested the point concentricity is very
good after adding this component (thanks to good
machining tolerances).
Aftershock
Archery labels the Booster design as stackable
but in this case let me we warn you to test your
point for concentricity after piling up more
than two collars as the manufacturing tolerances
do not play on your favor.
The booster is found online at U.S. $
12.99
for a pack of 6
(price as of today August 21, 2009 on

Conclusions
A very handy product: should not miss from your
toolbox. We routinely use them in our tests to
quickly change arrow weight setups.
