So, slightly different from the other Titan mods on here. This is a titan that fires micro darts/stefans but loads from a breech rather than couplered barrel or clip. I'm going to go on the assumption that people routinely remove the air restrictors in the Titan, because you need to do that in order to do this. I also plugged the overpressure valve inside with hot glue,s o that will increase performance...look at another tutorial for how to do that.

The pictures are large, so I'm just going to thumbnail-link them here, click on the thumbnails for larger view.

These are the pieces needed, minus the orange thing (was going to use it for something, decided not to). I forgot to take a picture of the step where i attached that grey piece of PVC to the white, but basically all I did was dremel down the white, hammer the grey PVC onto it, and use the dremel to round off the leading edge. I don't have the diameters for the PVC on hand, but I can get people the diameters if requested here.

Anyway, the combined piece of grey and white PVC is going to be the part you see when this is done. The shorter piece of grey PVC laying below it is going to become the sliding breech cover, and the clear plastic tubing is what the dart will go in inside the larger barrel...it'll make sense when you see it.

Posted Image

Next step is wrapping the whole piece of clear plastic tubing (except for about an inch at the end) in 3 layers of duct-tape. This is to take up the space difference between its outside diameter and the inside diameter of the rigid PVC barrel.

Posted Image

Next you force the tape-wrapped tubing down the PVC barrel. I had to use a hammer because of the friction, but that's the idea...nice tight fit.

Posted Image

Now you use a dremel to grind down the orange piece that the Titan's barrel usually screws onto so that the grey pvc fits snugly onto it. Again, needed a hammer to force it on...but it's sure not coming off. I followed up with hot glue around the edge for security, but I'm not worried. It should be noted that because I left the end of the clear tubing flush with the end of the grey "coupler", it has been forced inside the orange barrel where the Titan's air restrictor used to be.

Posted Image

This picture combines two steps. I ground down the inside of the piece of grey PVC to make it fit snugly over the white PVC, but loose enough to slide with some effort. Then I used a red sharpie to mark off the area to cut out for the breech.

Cutting out the slot for the breech.

Posted Image

Now, tricky thing. I hot glued the pieces I cut out back together so they won't fall apart. This makes it so you can actually place them back over hole before sliding back the grey PVC, making a tighter seal on the dart...

Posted Image

...like that. Note: that is the glued piece back in place, before sliding the grey cover over it. You don't HAVE to keep this removable chunk of plastic, but I find that it makes the gun fire better.

Posted Image

And done. You slide the grey piece up the barrel, pull out the cover, slide the dart into the tube, replace the over, slide the breech down, pump, and fire. I'll have ranges tomorrow, it's currently 12:40AM and a bit dark out. The gun currently is firing the original Longshot darts (think they're called Streamlines) as well as micro stefans.

Again, can get exact diameters and lengths of pieces if anybody wants them.

I guess you have some heavy duty industrial strength toilet paper holders. Do they advise you to wear eye protection when changing rolls?

Excellent, MichMorchaint! I wanted to do this to mine but wasn't sure how to. Props for a great and useful mod.

Yah, great mod. I am probably going to do the same to my titan. One question, does the breach mech lower the gun's range and/or accuracy that much?

Thank you all.

As far as I know the breech shouldn't lower any range or accuracy, but I haven't done any range tests yet. I'll try to get out and do that as soon as it stops raining (stupid weather). As far as accuracy, I've only fired it in my basement but it was dead on, so I don't think that's an issue (range of approximately 30 feet).

Ranges forthcoming.

Ok, got outside to test but ran into a problem. My backyard is between 140 and 150 feet long, and this shot the entire length of it no problem. THe issue was that at the end of the yard, the darts hit trees. Therefor I cannot get an accurate measurement, but we at least know that the gun will shoot 150 feet easily.

I also had my girlfriend shoot me with the gun to see what it felt like. At 30 feet it left a red welt on my back through a heavy sweatshirt and a t-shirt.

Successful in my book.

Hey nice mod, could you post the sizes of the pvc and tubing? I just got a titan and would like to do this but i don't know the sizes you used except for the 1/2" pvc.

I'll look when I get home tonight, but I believe the sizes are thusly:

The white PVC is 1/2".
The grey PVC is 5/8".
The clear vinyl tubing is 3/8".

I can verify that in a few hours, but that is what I think. Those are all ID measures, by the way, not OD.

Also, I have slightly modified the barrel system since I posted that. Can toss up some new pictures when I get home as well.

Did some measurements, Sizes are as follows:

White PVC - 1/2"
Grey PVC - 3/4"
Clear Vinyl - 3/8"

And the revised version of this mod:

Posted Image

I cut the barrle shorter to work better with my shotgun attachment, and added screws going through the grey PVC into the orange plastic on tjhe original titan. Holds it on better. I sealed around the screws with hot glue. I also put a screw into the bottom of the sliding part of the breech to allow better grip.

No offense, but the screws kinda make it look kinda ghetto.

Grey PVC is most likely 1/2" SCH40 PVC.
