| Our
new D-Fender "D-Ring" can assist in
eliminating extraction
problems in the M16, M4, and AR15. This
High-Tech, composite
"D-Ring" increases extractor spring force by
4x! As chamber pressure increases from
gas-port erosion, you will notice an
increased cyclic rate when firing in full
auto (less apparent when firing in
semiautomatic). |

Along with this increase in pressure comes a much faster unlocking of
the bolt, meaning that it is turning much
faster than normal. The fast spinning bolt
creates a centrifugal force causing the
extractor to open prematurely and therefore
not properly extract the case from the
chamber. This has been a problem since the
beginning of the M16 weapons program and has
often been misdiagnosed by gunsmiths and armorers as chamber problems, carrier-key
problems, or gas-ring problems. |
| Years of testing and evaluation have gone into
the D-Fender project. The
material that the D-Fender is constructed of will not break down
under normal weapon operating temperatures, nor will it melt from
cleaning solvents and lubricants. It will not become "squashed" from
the pressure of the extractor, or become dislodged causing the weapon
to malfunction. We mention these particular problems because we have heard
of several people trying to substitute the inexpensive hardware store variety
"0-Rings" for this use, and these failures are a result of that
practice. |
| We
build our products with the Professional in
mind, and understand that any failure in
your weapons system can mean the loss of
your life. We hope you will regard your own
life more seriously than you regard the
savings of a few dollars on an item that is
so important. |
| * The D-Fender is only manufactured in the
color black. The very early models were
manufactured in the color blue. Extractor
and spring not included. |
