Rt trouble shooting...
I am working on an old style rt mag and have it shooting without the barrel on but once I stick the barrel on it wont cycle. I stuck a few barrels on it but it didn't work with the other barrels on it either.
I was thinking it could be the spring or the bolt but I don't have a lot of knowledge about mags so that is just my guess.
Also I was wondering what the purpose of the powertube spacers are? Are they just to restrict air flow through the powertube and act as velocity adjusters or do they have another purpose also?
Thanks for any help or corrections!
