Didn't Captain Slug put Silicone Lubricant under the "Use with caution" section in the topic Plastic Safe Lubricants? It may have done something to whatever you lubed.

Can we get a pic or description of the plunger head?

Also, how tight are the darts you're trying to use?

If the plunger head seal is slightly bad and your darts are slightly tight, the darts won't move. Everything else looks ok, I'd check the plunger head and your dart fit.

Edit: In response to Icey, silicone is what 'Slug recommends in his post, and the Liquid Wrench stuff (I fould a description of the can) says it's safe to use on plastics/rubber, so the lube should be fine. Also, the wrong lube would cause the problems I've mentioned above, bad plunger head/tube seal.

Your AR bore hole looks too big, so when you shove the dart in it might be touching the plunger head. ARs are also to prevent that from happening. The dart would actually get stuck in the gap. Type/size of darts and type/size of barrel material would also help. If it's 1/2" PVC, standard suction micros won't fit, but streamlines and 1/2" stefans will.

Try cutting the coupler down by half, this helps on decreasing dead-space. Also, if you have any E-tape under the o-rings I would suggest taking it off and just use 2 stock NF o-rings. Also your spring power may be a large problem. Lastly dry off your o-ring(s) and lube it with some silcone grease, can easily be found at ace or any hardware store, danco o-ring lubricant is great stuff by the way.

EDIT: Also I usually do this to all my NF's, superglue the air restrictor plate and ring together.

I've tried tight stefans, loose stefans, and stock darts. None work.

I have two O-rings on the plunger head. It makes a perfect seal.

1/2" cpvc barrel.

I don't have any e tape on...I tried that once and it didn't work

I'm only using the stock spring. My local hardware doesn't have any silcone grease...so I'm stuck with this.

I'll try that I suppose. (cutting it in half)

Theres your problem. You need a new spring or to add more springs to the stock one. If you have a TTG spring add that or if you have a DTB and SF spring add those. Another good option is an ace 49 spring.

The dart won't escape the barrel... The stock spring has enough power to get a dart out of a 3" barrel. Cutting the coupler in half won't solve that problem either. Yes, both of your answers will help the performance, but it's not why the dart is getting stuck.

If I had to guess without a picture, I'd say it's the plunger head seal. When you say it's "air tight", how do you test this?

On the other hand, the guy who posted before me used the word 'fuck' a lot so he probably knows what he's talking about.

I prime the gun, I cover the coupler with my thumb and it stops halfway once I fire it. Then if I take my finger off, it shoots the other halfway

Does the barrel work on other guns? Does other barrels work on the gun?

Of course...

Does other barrels work on the gun?


Considering how it has a CPVC Coupler I haven't had the opportunity to try.

I'm just shooting to get lucky at this point, with a great seal (and everything else seems good) I don't know what else it could be...

This seems to be broken, is it? Maybe when you push your thumb against this (when you test the seal), you are pushing it back together (assuming the epoxy is cracked) so the seal is nice. But when you have a barrel, the air escapes from here from the lack of pressure. Try pushing back on the barrel when it's loaded and see if it fires.

With or without holding the barrel, stock darts have finally come out of the barrel, not stefans, just stock micros, all about a foot each...

So no difference.
