I've been working with my Xbow, and I've got a few questions about it.

 

First, Do I need to have the old spring, which is too long for the plunger tube? When loaded into the blaster, it has 3" of precompression, and is stored with said 3" of compression always on it. Should I cram a Longshot/Recon spring in, or cut down a section of [k26], or what?

 

Second, how do I improve the seal on the plunger head? Do I just need to apply lithium grease to it, or will I have to replace the skirt seal with something else?

And, if I were to get a good/perfect seal, would the original plunger tube be large enough to run a hopper?

Even some homemade replacement internals have trouble running a hopper, so no I don't think you'll get to that point.

 

You could just use a [k26] and leave out the original spring, but a [k26] will break the plunger rod and/or catch and/or shell around the catch unless you reinforce it.

 

Here is a very basic mod: http://nerfhaven.com/mods/rawray_xbow/I encourage you to search for and look up others.

 

As to the plunger head I'm not sure. Try lubing it. Try putting a few wraps of electrical tape on the end of the plunger rod to widen it and then stretching the seal over it. Last and probably worst option is putting teflon thread seal tape (which is not adhesive) around the seal. None of these will work as well as a complete replacement (plunger head and probably plunger rod), though.
