Section 3 - Machined Fill Caps for Benjamin Discovery Rifle, Marauder / Woodswalker and 1720T pistols

The Discovery rifle and the Marauder based pistols use a TKO Moderator that slighly inteferes with the fill cap attachment.

These fill caps will fit your rifles and pistols perfectly, and also match the CF finish of our TKO Moderators.

The machined caps can also be used on your custom Discovery based or Crosman 22XX project.

NOTE: The Benjamin Maximus rifle, although is based on the Discovery Rifle, does not require a machined fill cap when installing a TKO Mod.


Remember ... you can send us your original fill cap for free machining and return shipping. Send to the address at the bottom of this page...

Section 3 - Machined Fill Cap Replacement

  • The Benjamin Marauder Pistol, Woodswalker Pistol and the Crosman 1720T all share a great design that can be used as either a pistol, or converted to a handy carbine with the addition of the Crosman Shoulder Stock.

    These pistols incorporate an efficient valving system and when equipped with the TKO Stage-V Moderator, are some of the quietest airguns we have ever tested.
