Ok so I have a sm1.5k and I plugged the pump on it and did petg barrels. After shooting it for a while, the black piece (rubber sealer) on the end of the firing pin inside the air tank, kept coming undone if I ever pumped it 4 times or more. So after it kept coming loose time after time, I dropped some glue in there to hold it in place and it stays now, but now there is a small leak. I believe that the glue may have corroded the black piece slightly, or caused some irregularity in it, so that a small leak occurred. Any advice on what I should do? I was wondering if the black rubber sealer could be replaced...(I think its a faucet washer, but im not sure if thats correct and if it is, what size it may be)

Any help is appreciated...

Could a firefly sustain a handyman or NF spring? If not, what modifications would I have to make to the gun for it to handle the stronger spring?

And besides that and a petg barrel mod, is there anything else I can do to acheive the greatest distance possible?

The title says it all. I have two secret shots that I have modified and I am not satisfied with their velocity. I want to replace the original spring with a stronger one, preferably one that gives me ranges of 60'-70'. Does anyone know of a spring I could buy at an ACE store or at another hardware store that will get the job done? The main problem is finding one that is skinny enough to fit inside the plunger tube (i.e. a handyman spring is too fat)

Thanks

The title says it all. I'm using vinyl dye to paint my guns if that matters.

im currently in the process of modding my nerf guns but i have come to a difficult decision: 9/16" brass or 17/32" brass? im not sure which one would suit me better, im hoping to mod all of my nerf guns with one or the other so i dont have many different types of bullets lying around. any advice would be greatly appreciated.
