4. Go to a hardware store with the stock spring and see if you can find something stronger that you can replace it with.
4: most of the springs at my local hardware stores are not that long or are only good for reverse plungered blasters. And also because the prime on this thing with the stock spring is extremely heavy.
ALSO, this blaster was bought from goodwill for $6
FYI This is a good replacement spring: https://www.amazon.c...s/dp/B000BQOUIQ
Or you can get it at Home Depot http://www.homedepot...16084/202045472
Questions:
1. When you removed the air restrictors did you perhaps cause a leak between the plunger tube and the front plate (where the air restrictor was)?
2. How far is it shooting? How far do you want it to shoot? I mean, when Make Test Battle singled theirs they only got 160ft/sec max so I wouldn't expect to get yours to fire even 70feet flat especially with the stock spring.
3 What darts are you using?
To troubleshoot, you may want to take off the RSCB entirely. just put a single shot barrel on it and see how it shoots.
