Do any of you have experience with this and is there a reason I shouldn't do it? I included some images for reference. I speculate this this will allow the plunger to travel faster inside the cylinder because there is less pressure resistance buildup from the orifice part which will allow for more of the spring's potential energy to do work on the project itself. I'm tempted to open up the holes or create more of them to let air move more freely past this part into the barrel. It'd be sort of like putting a governor or speed limiter on a vehicle. I think this part it is an orifice which intentionally reduces air flow out of the cylinder to limit the projectile velocity. All the pressurized air must pass through and around this disk before reaching the barrel to actually push the projectile out. It appears the disk sub-assembly has two functions which are 1) seats the round correctly in the barrel when the plunger is primed, and 2) limits airflow out of the primed cylinder into the barrel while firing. While I was disassembling the cylinder I noticed that there is a disk with holes drilled into it in the bottom/barrel end. I believe the blaster components are made of PVC, so I might use some plumbing clement and spare plastic I have laying around to brace some of the components the spring acts on. I've only seen people throw in the 15kg rate springs so I thought I'd try to squeeze a little more out. Starting with velocity, I got an 18kg rate Worker spring which is sold for the Kronos but looks like it should be a drop-in fit. Mainly, I'm trying to improve the accuracy of the blaster, buy also the velocity/distance of the rounds. I'm in brand new territory and you guys are the experts here so I thought it'd be best to hit you up before I did anything too permanent. I got an upgraded spring and also bought the Worker pump-action kit.

I just picked up a Rival Helios and am already at work on it. The TL DR is that I have a Rival Helios and want advice on accuracy and performance mods.Īs a 30-something year old 'kid,' I'm, a long time Nerf fan but am new to modding them.
