Well I got tired of my angel breeched longshot breaking with that stupid tiny nub.
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

21/32 brass
cpvc
1 1/4 8-32 bolt
1/2 pvc
Glues
*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.

Awesome job.

This is somewhat unrelated, but you can also make a CPVC LS clip breech by housing the CPVC inside an AT2K pump tube which has an airtight fit with CPVC and has a very good fit with LS clips. I will post a writeup or some pictures some time.

[Soothsayer]

This is some intense stuff, lou. Keep it up.

[xbox180]

Cool, when I had created my 180 breech the main problem that I had found was that there would be to much friction between the clip and the 21/32.

[ice]

How do you prime it? Just by pulling on the screw uptop? Besides that, looks great.

[anon-dude]

@ice: Didn't you do something like this? and What ever happened to your update/rev.2 breech?

@louiec3: Great job overall. I would prefer to have the priming handle even though the blotsleds are a pain in the @$$ to mess with, in my opinion. Any way great job.

[Phibonnachee]

Excellent work, does your longshot still use the boltsled? If not then the priming handle seems awfully small and awkward to prime.

Judging from the pictures I would say no it doesn't

[CA13]

So, you basically un-singled an LS?

I think it's cool, I'd probably would attach an extension spring to the brass bolt sled to it retracts as I let go.

[Zorns Lemma]

The brass doesn't move and there is no boltsled.

Nice work loucie3. I think the easiest way to get clips to load easier requires redesigning the 21/32 brass. Instead of making a sleeve that covers both the bolt and the barrel, just cover the barrel and have a thin, slotted top strip to keep darts from sticking up. Then flare the brass around the barrel receiver so that the bolt can slide in and connect easier. That way you solve the problem that the other de-singling longshot guy had with darts popping out, without have to increase the diameter of the piece the magazine must fit around.

[louiec3]

Well I fixed the clip issue, made a handle because you guys don't like a horribly uncomfortable bolt, got more pictures, and a new video!

The clip teeth were catching on the 21/32 I dremeled it down so it acts like a ramp on the cpvc.

You could also do what Zorn's Lemma said and make it a 1/3 pipe or maybe even a 1/4 pipe.






Firing 4 shots the second shot jammed not in the breech but in the clip, because I took the lazy way when making my stefan clips. So now I need to re do all of them. I used wire instead of making polycarb planks to stop the darts going back.


CA13- I never singled this but you could un-single an LS by doing this. You could add an extension spring to the bolt, but I won't. Also there is no boltsled.

anon. dude- There isn't the stock priming handle precisely because boltsleds are a pain in the ass.

xbox180- I never had the problem with too much friction between the clip and 21/32; it may just be because I have only used stefan clips with this and they open up more because the joint at the top isn't connected as strongly as in stock clips.

cheesypiza001- I had seen atomatron use a 2k pump tube for his ls here. That was my original plan except using the brass; then I had a brain blast in the middle of the night, and made this instead.

Zorn's Lemma- I have had problems with breeches before, because I couldn't flare the brass around the halfpipe, but beveling down the edges of the bolt serves the same purpose as flaring it out.

[anon-dude]

I LOVE IT! with the new priming handle and the fixed issues I may just have to make one...

[louiec3]

1 more update----(proof anything can be perfected)

This has to do with the air seal around the plunger tube.
It started today with me finally getting to range testing it was a respectful 90ft. Once I was done I put my finger on the barrel and pulled the trigger, and was shocked by the plunger slamming in the gun; unlike my other guns where it slowly comes to a stop.

I went upstairs and opened it back up.
I grabbed the breech, and plunger tube. After a series of tests I found the leak was where the stock black piece was in the plunger tube. I had cut it off so I couldn't replace it, so I made a new solution.

I made the breech slot in the top longer so the bolt will touch the barrel and kind of pull on the plunger tube making a seal. The bolt was originally made to touch the barrel when closed, but I couldn't get in in fast enough before the glue dried.


Then to keep the seal I had to keep the bolt tight to the plunger tube. Easy solution add A rubber band.

There was a box like thing that has to go.

Make sure the rubber band is still stretched when the bolt is closed. I only used 1 unlike the picture that has 2.

With the rubber band you still need to close the bolt manually, but if you add more it will close automatically. But make sure you add enough so the bolt closes completely.

Also To make your life easier add a 2nd bolt behind the first one this will stop the bolt handle from rotating.


Now I went back out and range tested it...


With single bb stefans and a [k26] spring I most of them landed between 95-110ft.

The highest was 115ft and lowest was 12ft (the bb and glue came off the stefan).

[Merzlin]

Sweet deal. The only thing I propose is adding a more durable way of sealing the bolt, like an extension spring, or a reallllllyyy strong rubber band, ones that can be bought off mcmaster

[angelfalcon]

I dislike the priming rod. I'd use a modified version of HeretiCorp's LS foregrip, so as to get shotgun loading and no boltsled.

Other than that, I think this is one of the best innovations for LS, right behind the original Angel Breech and Slug foregrip.

Just curious, for what reasons did you choose to think that this innovation is behind the Angel Breech? As far as I can see, this breech is better in every way.

[angelfalcon]

It was more of an innovation, everyone saw the bolt system and thought, WHAT THE FUCK AM I GONNA DO WITH THIS? But Angel, being awesome, stepped right up and found a way to make the LS a beast. This system is probably more effective in every way, agreed. But this doesn't absolutely change the future of the LS like that did. This is just an extremely sexy method of de-crapifying a singled LS.

[louiec3]

Merzlin- I would rather have an extension spring, but I have hundreds of those rubber bands right now.

angelfalcon- Can you not read the first post this doesn't use a boltsled at all, as in there is no boltsled in the gun, on the gun, or within 50 ft of the gun.
-I do plan on making a foregrip for this at some time but it isn't a priority right now.
-This breech is better in many ways than the angel breech, but I still give credit to Angel for his breech because that is what inspired me to make this. I just wanted to take what he did and make it even better.
-Why does everyone think this is only for singled LS's? I would put this in a perfectly good LS because the breech works better than other breeches.

Just to let everyone know you can use this same style of breech with mcmaster petg, and other brass sizes. (you would just need to find the proper sizes.)

[angelfalcon]

anon. dude- There isn't the stock priming handle precisely because boltsleds are a pain in the ass.

That's why I said it. That priming handle looks uncomfortable, you don't want to use the stock priming mech because of the boltsleds. A HeretiCorp foregrip would fix the uncomfortable priming handle without having to worry about finicky boltsleds - best of both worlds, have your cake and eat it too.

I have basic comprehension skills. No duh, there's no boltsled. You pull back, the back end of the CPVC pushes the plunger head back until it catches, you pull forward and chamber the dart. No boltsled required.

That's just my solution - idea, rather. Carry on being an ass to everyone offering solutions to the little problems.

Edited by angelfalcon, 14 January 2010 - 08:00 PM.

[louiec3]

angelfalcon- The priming handle I currently have on it is very comfortable to me. If I came off as an ass I'm sorry but you're post seemed as though you still believed that there was a boltsled in there, and a lot of people do have difficulty reading the part where there is no boltsled.

so as to get shotgun loading and no boltsled.

[tn81]

Great mod it look like it's easy to make.

[Clair]

NICE JOB!!

[Clair]

awesome!! can u deliver to hk?? and how the fare?

[angelfalcon]

Sorry louie, you did kinda come off as one. But being man enough to admit maybe you did erases that in my opinion.

If that priming handle feels good to you, go for it!

[archangel24]

Bravo Bravo nice job. I would do this but i can't afford brass, ugh.
