I set out to fix the breaking problem the only way I knew how with bolts, and you can't have a bolt in an angel breech so I designed my new breech and today I built it.
This breech also eliminates the need for a breakable boltsled.
*Edit- Scroll down for an update.
What you need
1 1/4 8-32 bolt
*Dremel is highly suggested
Open up Your longshot do whatever spring upgrades reinforcements and integrations you want.
I did the front gun integration, replaced spring with a [k26], and added a washer to the black piece at the back of the plunger tube.
Onto the breech...
Cut a 5 3/8 length of cpvc bevel down one end. Glue in a 1 length of brass that fits snugly in the cpvc into the end you beveled down.
Drill a 1/8 hole .5 from the front of the beveled end then tap it for 8/32.
Take the black piece from the front of the plunger tube cut off part of the tube but not all of it probably around 3/8-1/2 in, , and dremel it out so it will fit cpvc snugly.
Also cut a section of 1/2 pvc that will sit flush with the ends in the black piece.
It should not look like the picture there should be about 3/8-1/2 of the stock bolt on the black piece.
Gently persuade the 1/2 pvc onto the bolt you made above( I used a hammer).
Super glue that into the black piece and kill some deadspace with hot glue.
Cut a slot in the your 21/32 about 3.5 long and wide enough to slide your 8-32 screw in. It is .5 from one end.
Cut a halfpipe starting 1 inch from the end that is 2.5 long. the slot form above should be in the middle of the halfpipe.
The barrel is made from a 8.75 long length of cpvc. Bore out one end about 1.5 into it and dremel the end down so it is like a ramp.
Test fit everything together,and glue the barrel onto the breech cover.
Glue the barrel assembly into the thing that holds the dart tooth.
That should be your finished breech.
Install it in your longshot, and close it back up.
Right now I need to work out some problems. Particullarly, the clips are hard to load right now I need to open it back up and fix it It will be easily fixed.
And just because I have an ego I will call this breech the #78 breech.
Once again because you all like videos.
The video doesn't do it any justice this thing is a lot louder.
Ranges are pure estimates right now, but I think it is around 90ft.
