Got new FX Dreamline in mail and mag would not fit into gun..
Thought I had a problem with finish of Magazine , so I took it apart.
Problem was barrel was too far in, stopping the mag.
I adjusted barrel and now the mag fits..
Their are no pictures or video's online of this newer magazine
Their are 4 holes in case for return spring and I think Mine is now too strong return and may distort pellets
Thanks for responding and hope you can help.
Be careful when you remove screw and lift cover, the spring might come out of hole
Need to try and count turns..
Thanks Mark
