Please excuse my lack of knowledge because I haven't done much (any, really) modding...
Then this modification is going to be out of your league.

I didn't have to do this. Instead I slid a section of 17/32 inside of it and pounded the edges lightly using a brass hammer. Then I sanded the exterior smooth.Oh be sure to lube the top half of the half pipe of the main barrel. This helps the sliding of the 19/32" and makes cocking the gun and shotgunning darts alot easier.
The breech slides flawless now without any oiling.
The hang up I have now is getting the hardpoint affixed to the outside of the bolt.

I'm getting around 110 feet using 9 inches of 9/16" nested inside 8 inches of 19/32". Which is awesome because that's about as far as my Titan will shoot with an 8-inch CPVC barrel.
I just need to finish modifying my magazines next. This breech design works best with magazines that have the "stefan compatible" changes made to them since the bolt opening can only be so big and still work.
The dimensions on my parts ended up a tad different as well since I didn't have exact measurements to work with in the beginning. SO I had to come up with my own based on just the concept.

I cut the stock bolt piece down to 1-1/2" in length measured from the end that ends up inside the plunger chamber. What dictates the length of the "lip" you cut from the 9/16" barrel piece is largely determined by how far forward the 9/16" and 17/32" pieces extend inside the new brass bolt piece.

Same sizes of brass. Only difference is the lengths I cut them to.So, CS what different sizes of brass did you use for that? Same as Forsaken?

Is using this bolt design incompatible with shooting CDTD's? Are they just too long for it to open?
Oh you can use CDTD's its just you have to convert them even farther by shortening the length of the dart. In other words, you will most likely need to cut off 1-1.5 inches off the tail end.

The breech only works well with magazines made "stefan compatible" incase anyone was wondering.

As I understand it, the use of the 1/2" brass is for the darts to "nest" snugly in, a-la traditional nesting, and it nests inside the 17/32" in the front of the breech for an airtight seal. The 19/32" is so that the actual breech that grabs the darts is a little wider, making it work smoother... right?
Do any of you who've done this think I will be able to construct a working longshot breech using only 9/16" and 17/32"? I would forego the extra nesting of 1/2" in 17/32"... Is the nesting of 1/2" in 17/32" brass absolutely essential?
And, Is 9/16" brass wide enough to grab darts without jamming?
Thank you for your time.

The 1/2" brass is not used for nesting it is used as a hollow rod that will push the darts from teh clip into the main barrel while still allowing air flow.
If you click on the link in my last post it will describe the breech better.
I think the Veg made a longshot breech that is a bit more simple than mine using only two sizes of brass.
It is in the mods directory. The only difference is that breech does not allow for shotgun loading.

Have you had any issues with your breech system jamming? There's mention of TheVeg's breech being finicky, and I don't want that.
I watched the video explaining the breech (thrice) before posting; that's the only reason I understand anything about this...

Oh ya, very nice looking.

You tighten it while looking inside of the barrel with a flashlight and stop tightening when you can see a divot. Then simply roll it around.

1) FA24's video shows the clip being loaded with the bolt in the forward position. I'm assuming this is to prevent the top of the magazine from catching on the bottom half of the exposed breech. That being said, do the magazines show any sign of wear from being stretched around the 19/32" brass?
2) Is e-tape really enough to keep the front barrel in place? Without the use of glue couldn't the front of the breech gradually rotate just a little out of alignment?
I guess I haven't seen mention of either of you using this in a full Nerf War yet and I'm curious as to what type of issues might arise after a day of constant use and abuse.

What dremel bit did you use for your cuts? I only have a few basic bits (sanding, grinding, cutting wheels, etc) and was wondering which one I'd have to pick up for smooth brass cuts. I built a mock-up brass breech just from pieces I had lying around, and I see the only hold up for myself being cutting the half-pipe. Any advice?
Amazing breech, btw.

Instead of e-tape I ended up using 1/16th" diameter o-rings shoved in place with a flathead screwdriver. Kept it very solidly mounted but still removable.2) Is e-tape really enough to keep the front barrel in place?

1) The magazine lips are not stretched over the 19/32" brass. In fact they are a bit looser.
2) The amount of E-tape I used was still very tight that it took a lot of muscle to pull it in and out of place.
I used E-tape to keep it in place during the initial testing and making sure everything would fit right. After I knew the front barrel was in the position I wanted it to be in for the rest of time, I decided to use some Fishing glue to help keep it in place.
FA,
What dremel bit did you use for your cuts?
I used a fibreglass reinforced cutting wheel. But any cutting wheel will do. Just make sure when you cut brass with a dremel that you smooth out the edges a little with a sanding bit. This will help keep your breech from shredding darts.

Thanks. Definitely about to make this my summer project. Just need to see if Hobbytown USA is restocked on brass yet.
