Not the best of weeks. Lets start with the positives.
The Longshot's foregrip has been painted and the Tactical Light has been secured nicely so it can be disassembled. I'm really quite fond of it now.

Next, I made a double-barreled NiteFinder. It's pretty cool, but the ranges are somewhat disappointing, even for a first gen NF. With both shots it only gets around 30', and firing one gets around 40-45'. Aside from different barrel material, I don't really know what do do to make it better. But it's a pretty cool sidearm nonetheless.

Next, I need to find different springs. The ones I got were around 4", and were too big for a NF, and too small for the LS. It was also REALLY heavy gage. It has quite a kick in the LS, but It wasn't the right one for the job, so I'll look for another one.
Next again, I found THIS gun. No idea what the hell it is, the logo wore off years ago. It's chipped and broken in several places, but nothing past fixing I believe. Anyone know the name of this gun, have any links to mods, or pictures of internals?

And I think I messed with this, because It's not working how I think it should. It's supposed to pull the metal rod backwards, which releases the air, but i can't figure out how. Grrr.

I have an idea for how I could fix it, but it's DRASTIC. Like huge internal reworking drastic. But just getting a picture of the internals would really be better.
Oh, and does anyone know how to remove the turret? For the life of me, I can't figure it out. It fires Nerf Megas, so I can't test it at all until I give it a barrel replacement.
And lastly, I've been trying to give the Longshot a barrel replacement. This is my first experience with having variable length barrel material (I've only worked with roseart barrels and a fixed-length piece of brass). I got some 1/2" CPVC, which fits darts pretty darn tight.

I tried loading in a dart tip first, like it would be in the LS. This is as far as I can get it in without really pushing and crushing the dart. This couldn't possibly work. Is this the wrong material for a LS barrel replacement, and what should be substituted. In TIG's write-up, he used aluminum, which I haven't been able to find. I also haven't been able to find lengths of brass. Reccomendations would be appreciated.
As a note, I tried loading in darts tip first into both the RoseArt barrels and brass. Both worked much better and easier, and were able to be put in with little issue. I think the brass has too small a OD though, and it's only about 4" long anyways.

So there it is. Sorry for the very long post. Answers/ references/ advice on any of the questions would be greatly appreciated.
Thank you all in advance. i don't know what I'd do without you guys.
