I have received
many inquiries over the years about the impact strength of the
stamped steel that is used in Bitter End Airsoft Gear. Rightfully so; players want to be sure that Bitter End Airsoft
Gear will protect them from incoming rounds.
The following
test was conducted using my CA M4 variant; highly modified AEG
platform Sniper rifle.

Ammunition that
was used for this particular test was the .20 gram 6MM BIO BB's
manufactured by Excel.

This AEG was
Chronographed using an X CORTECH X3200

The FPS varied
from between 525 and 535 FPS with the .20 gram 6MM Excel BIO BB
during 6 test round through the Chronograph.
Previously I
have conducted similar test using a much heavier .36 gram BB
netting similar results.

The stamped
steel does a remarkable job at dissipating the energy of an
incoming round;
the surrounding metal aids in the diffusion, as the energy is
absorbed across a larger area.
As a side note;
small impact dimples can be manipulated back into place if you
want to keep
your gear looking new. Some players allow their Bitter End Gear
to accumulate all of the wear
and tear that has been dished out, opting for a more battle worn
look.
In the
following photograph you will see there is a BB that appears to
be sitting on the stamped
steel, in the depression of a stamped steel sample. This
is the 6th round that was shot intentionally
into the same location. The metal has stretched enough to grab
the back of the BB to hold it in place.
This is an
EXTREME test that you would never encounter in an Airsoft game
situation.



In conclusion;
it is my opinion [as well as thousands of other players across
the World] that
Bitter End Airsoft Gear will, has, and will continue to protect
players from a high speed impact
that might occur from an Airsoft replica during normal and safe
play.
