Do you want your old, first generation, Benjamin Marauder air rifle to have the performance improvement of the new generation two (Synrod) models?

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.

This kit includes replacing the following parts:
New Valve (Part 1764-100)
Depinger (Part 1764-064)
8 x O rings for Fill Adapter, Gauge Port and Valve, Part 1763-026
2 x Gauge O ring, Part 1761A203
4 x Breech seal, Part 130-036
2 x Bolt probe O ring, .177 cal, Part 1763-058
2 x Bolt probe O ring, .22 cal, Part 1763A023
2 x Bolt probe O ring, .25 cal, Part 106-005

Archer Airguns Gauge Port Filler Tool

The 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.

Reviewer: Chris P from Alabama  
If you have a gen 1 M-rod you need this kit. Install was easy and this increased the number of shots by nearly double. Shipping was fast. Buy this kit!
