A member was contacting me asking how my gun fired exactly, so I thought I should add a video of the action.
Also here are some more pics of the updated version of the gun. I changed the grip so its now a PVC handle with a nice foam grip. The Springs have not changed, although there have been minor adjustments using duct tape to improve seal.
If your like me who put the stock LS and BBB spring inside your LS before any reinforcements, chances are you had to single your longshot. Problem here is that singled longshots make the clips obselete and greatly reduce the ROF. There have been many solutions before, such as ice's string mod and hereticorps foregrip, and if your boltsled has not broken then this mod probably doesn't apply to you, but my solution is easier.
The Completed Gun
I am very sorry for not have made this earlier, it really helps clarify everything I did in this mod and make it easier to understand. I didn't realize how easy it was to do, but now that I have this pic up i hope it helps everyone understand how my mod works.
What happens is the bolt cpvc part pushes the dart into a coupler, and at the end of that coupler is PETG. PETG is looser than cpvc so darts slip in easier (of course PETG doesnt stay in the cpvc coupler really well so you need some e-tape to keep it steady).
So what you have is essentialy a PETG barrel in a cpvc coupler, and a cpvc bolt that pushes the dart into the PETG at the other then of the coupler.
What I did is I took a pipe of cpvc and glued that to the part where the plunger head meets the black plastic inside the plunger body. The length of this pipe is very important, too long, and a stefan won't pop up when the magazine is present; too short and it won't reach seal properly. At the other end of the shell, I put a coupler at the end of that for the cpvc to stick into (See pictures).
At the coupler, I stuck some petg into the coupler which is used as the actual barrel (e-tape around it to ensure a tight seal around the coupler). Also, I put some popsicle sticks and washers to allow the stefans to be smoothly guided into the petg nested in the coupler.
To make the handle, I drilled 2 holes into the cpvc attached to the plunger head. Then I drilled holes into the cpvc tee and nailed the two together at an angle. I cut a little into the shell and to the sides of the tee for the bolt to fit snugly, then I simply attached some cpvc to the tee which is used for the bolt handle. I also glued between the tee and the shell to ensure no air is leaked into those holes. The reason for this complicated attachment, is because any other method will be blocked by the wings of the magazine and will be unable to slide back.
Here is an image of the breech open
When the bolt is pulled back, the cpvc primes the gun as well as allowing a stefan to pop up from the magazine, then you simply push forward and the stefan will be moved into the coupler where it will then be inserted into the petg.
Ranges: 80-100 ft -probably cause my barrel material is too loose.
Also, because there is no stopper of any sort above the magazine, sometimes multiple bullets will pop out when priming, so I need to keep my thumb there for that purpose. However, this allows me to easily breech load multiple stefans into the clip at any time. I can still get off a shot about every 4 seconds.
Overall, I'm happy with this mod because it gives almost the rate of fire of a regular LS with the power of as many springs as you want. I will be happy to clarify anything that didn't sound too clear.
