I recently received a Longshot for my birthday, and began modding it as soon as I could. I basically did The Inventor Guy's mod, but instead of a foam seal I did a nested brass breech- a half-section of 17/32 and a 9/16 barrel. This results in a almost perfect seal, and gives you the nested brass effect. Using the funky hot-glue seal and the stock spring, I got ranges a little under that of my angels BBB. I am not going to post ranges, because I recently discovered that bbs do not give you an adequate weight for stefans, so none of my ranges are good . So if anyone asks "how are those ranges" or anything like that, they have been skimming... I am hoping to get some o-rings soon, and I will post the improvements.

The breech consists of a half section of 17/32 brass a bit longer than the length of my darts and a full section of 17/32 that completes the seal. The darts in the clip are pushed into the half section and then the bolt is slid forward so the half section goes completely in the 9/16 barrel and into the full part of the 17/32, giving it a good seal. The dart does not go into the full part of the 17/32, but it could if you took the trouble to make the edge perfect. (right now mine is bowing in) Make sure that at least a bit of the half section is in the barrel when the bolt is all the way back to avoid unnecessary jams. Oncce you clear the hole where the dart used to get pushed in you can just stick the 17/32 in there about an inch, and add some epoxy, not hot glue, around it.

This system is not completely reliable, but it works fine unless you push in the bolt really fast, then the dart sometimes gets pinched in the breech, and it is obvious when it is. This is pretty complicated to operate, because it stumped all my friends at the war... there are many things you can do wrong...

Don't hesitate to ask any questions, usually I can get on the computer at school for about 10 minutes a day, so expect answers around 7:00am and anytime on weekends. I have no time after school, but I hope to get better pictures next weekend.

Do you spell it Breech or Breach? I'm not exactly sure... Edit: Got It! Thanks Lizard Messiah!

Anyway, on to the Pictures...


View from where the sliding door would be. I left it out so I could always see what this thing was doing.



Dart in open breach. View from magazine well.



Open Breach. View from magazine well.



Breach halfway closed, view from magazine well. Dart in breach.


The pictures are big, I know, and there are a lot of them. If these is anything I did not make clear please tell me. Any comments are welcome.

Am I the first to do a brass breach on the LS? That is pretty cool...

Hope you liked it,

Nice. What kind of ranges are you getting?
As far as I know, you are the first to do this.

I was going to do the Inventor Guy mod to my ls , but now I guess I'll be doing this one. Good job Veg!

[The Crackerjack Man]

WOW! Im definatley doing this mod and if i add the shotgun mod that would be awsome.

Looks great, I think that may be the solution to my horrible jamming problem I've been having with TIG's mod. But, I do have some questions. First of all, how long is the 17/32 section? Does it go into the 9/16 section very far? I know that with my brass it's tricky to get the 17/32 to fit into the 9/16... perhaps too tricky to really work with this breech (breach?) system. When you say you can't do it quickly, does that mean you have to do it really slowly? I'm just wondering how combat effective this is going to be if you have to sort of baby it into the breach (breech?). What I really want is to take advantage of the LS's ROF since the spring I added isn't that strong and I can cock it pretty easily with one hand still, so being careful with priming is not quite what I'm looking for...

Edit: It's breech.

The 17/32 section goes into the 9/16 completely all the way up to the plastic piece, and there is about one inch of full 17/32 in the 9/16. It takes a lot of checking the fit and this might not work with longer darts. I really don't have a problem unless I ram the bolt close to as fast as I can. You need to mod the clips too. I will get better pictures, and turn this into a full writeup next weekend.

Now, back to Homework.
