This might help you.

Im going to do this as soon as I get my FF. I think that I will add a NF spring, or a SS2 spring, if nerfer75 doesn't buy it from me. Is that silicone stuff glue? I couldn't tell by looking at the picture.

It looks like a silicone sealant used around sinks and bathtubes.

Do you mean you want to have the planger start the dart moving
,and then the airtank act as a booster kind of like how multi stage rocket work???

That is really cool looking.

By the way streching the spring will damage the spring.
At first you will get better ranges, but the spring will return
to its original shape after abit, and be weak than before

You have to remember that the LS has shitty seals, you'd probably need more than 1 pump to get ranges comparable to a regular LS+ extra spring. You might as well just keep the spring powered part because you'd still need to use the bring the bolt back, then push it forward if you used air. No offense but this seems redundant unless you're putting a titan in there for the extra range.

I want to make a pneumatic longshot that's singled.
Thanks.
