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 service 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 parts while keeping your existing barrel, trigger and all other parts.

Archer Airguns uses factory-specified lubricants, parts and some special Crosman designed fixtures (as used on the Crosman production line) to ensure high quality reassembly. You receive a 90-day warranty on the upgrade. The old valve will be returned to you.

Archer Airguns will completely inspect, disassemble and upgrade your air rifle. This service includes replacing the following parts:
Valve (new Part 1764-100)
Depinger (Part 1764-064)
Fill adapter O ring (Part 1763-026)
Gauge port O rings (2 x Part 1763-026)
Gauge O ring (Part 1761A203)
Valve O ring (Part 1763-026)
Barrel seal O ring (Part 1763-058, Part 1761A023 or Part 106-005 depending on caliber)
Breech gasket (2 x Part 130-036)

Your gun will be given a 24-hour leak test and a Chrony test of muzzle velocity before being returned to you within 15 working days of us receiving it. For even faster turnaround, choose our 10 working day Expedited Service option.
