Ya so i noticed very few ls mods on this site, so i decided to open mine up, and with a little help from the folks at nerf haven, see what i could do. heres what i got:
AR removal
new breach
new barrel
lsfg intigration

materials:
1/2 inch (type L i think) copper tubing
5/8 inch brass tubing (should fit over copper tubing tightly)
hot glue
wire
epoxy
super glue

tools:
power drill
knife
file
hacksaw

cost:
around 12 dollars, depending on where u get materials

warning: with this mod you will only be able to load stefans, which is not a problem and do not let it deter you from doing this mod. however, if you are dead set on using stock darts, you may simply ignore the breech and barrel mods. there will also be a brief stefan making tutorial at the end of this ible.
also note: stefans are more powerfull than stock darts anyway.

Step 1: Open Up the Beast

take apart your longshot. pretty self explanatory.unscrew all the screws. it helps if you either leave the screws in there holes or stick them in a cardboard template. it should look like this when you open it up.

Step 2: Take Out the Junk

remove all of this stuff. you don't need it and it makes things a pain.

Step 3: Cut the Breech and AR Removal

now take your hacksaw and cut it nice and straight as shown in the second pic. sorry about the 2 unedded pics. sorry about no pics on air restrictor removal, just dump out the black thing and drill right through with a power drill through the back. all the stuff should just dump out after that. if not just runn it through with the drill. you should be able to see the plunger head when you put it back together. if you have questions comment and i will try to help.

Step 4: New Chamber

now take your 5/8 inch brass tubing and glue it onto the black thing. make sure its nice and even and it will save u a lot of trouble. i used epoxy for this. it also helps if you have a little bit of PETG or something that will fit inside that will help it stay even.

Step 5: Add the Bolt Sled Nub

remember that stock breech that you cut off? well i hope you saved it because we will be needing it. cut off the bolt sled nub, the orange part in the attached picture. now take your 5/8 inch piece of brass and cut score marks in it with a knife that you don't care about or can easily sharpen. these should just be little scratches, not huge slits. now put on a TINY drop of super glue. put it back in the LS but don't close the gun. now close the breach compleatly and slide the bolt sled forward. now make any adjustments in the highth of the nub by sanding or cutting it down. then glue it on with an exessive amount of glue. i use super glue, and that will only hold for about 50 shots. i have also tried amazing goop, multi-purpose cement, and epoxy and none of them have been able to hold it. i have heard that either fishin' glue or zap a gap work well, but i cant find any.

Step 6: To the Other Side.

now take your nice piece of copper tubing and cut it so that there is a piece about one dart length long that is thin enough to pass through the slit in the top of the clip. wrap about one layer of electircal tape around it and shove it in like shown. there should be no full copper pipe sticking out beyond the farthest edge of the breech. you will have to fiddle with pipe sizes for a while. if the breech will not close, it is either getting stuck or the copper piece is to long. if it is not cocking, your piece of brass is not long enough.

Step 7: LSFG Integration- Step One

this step will be to integrate the lsfg, or long shot front gun, the little piece of poo that usually sits on the front of the stock gun and actually decreases performance. the first step will be to cut the longshot and lsfg down to size. sorry there are no pics of this beforehand. first open up the lsfg and gut it. do a simple AR removal and then put it back together, just without the internals. now. mark it where you want to cut and either dremel or hacksaw it. do the same with the longshot. the image notes will give more discription if needed.

Step 8: Lsfg- Step 2

glue the shell into place, one side at a time. next add the internals, and take some wire and tie the too triggers togther. again, more detail in image notes if needed.

Step 9: Re-assemble.

pretty self-explanatory. put it all back together.

Step 10: Brief Stefan Making Tutorial

go to the store and buy some 1/2 inch foam backer rod. cut it into 2 inch segments and straighten them with either hanging it before cutting or a blowdryer afterwards. now take a hot glue gun and burn a small hole into the top and add a small metal bb into it, then cover with hot glue and bam! your done.

Step 11: Updates

this will be where i post any new updates on my LS or any other nerf stuff:
working on a new breech that will shoot shotgun stefans
modded lsfg to shoot either shotgun or mega stefans, but am having trouble with the catch.
shotgun stefan breach failed, so went with the angel breech
lsfg is in pieces and don't work. kinda just gave up on it for a while.

Step 12: Cant Build It? No Problem

if you are having any problems with anything nerf and just want to buy it, shoot me a pm.
I WILL SELL STEFANS FOR CHEAP!
