you want your old, first generation, Benjamin Marauder air rifle to
have the performance improvement of the new generation two (Synrod)
If so, this comprehensive kit provides all the parts and a special tool so that ,you can upgrade your Marauder to with new "generation two" factory valve and depinger. Crosman
advertises that the new valve provides 30% increase in shot count while
the depinger changes the sharp "ping" to a dull thud resulting in a
less-perceived noise level when firing. Of course your air rifle is
otherwise unaltered. This service gives the benefits of the new valve and depinger
while keeping your existing barrel, trigger and all other parts.
As with other Archer Airguns Kits, this kit includes two sets
of the O rings required to undertake this Benjamin Marauder air
rifle upgrade. This
provides a good supply of spares "just in case". Specially packaged by Archer Airguns. These seals fit both the
original and new, synthetic "Synrod" model Marauder air rifles.
Includes barrel O rings for all calibers, .177. .22 and .25 caliber.

Archer Airguns Gauge Port Filler Tool
unique Archer Airguns gauge port hole filler tool is a very much simplified version of the jig
used by Crosman on the Marauder production line to ensure that these O
rings are not cut during reassembly. It simply fits into the gauge port
hole in the main tube during reassembly and stops the O rings from
swelling out into the hole and then being cut as they pass back into the
pressure tube. Just hold the tool against the gauge port hole using one hand as
you install the valve and gauge port. The O rings will be able to pass
by without being cut and your Marauder air rifle upgrade has a much
higher chance of being successful.
