socom 16 tightbore barrel

[steelheader86]

I have a socom 16 by echo1 and bought a modify hybrid 6.03 inner barrel because the modify has the grooves for the hop up unit in the correct spot which is different than most guns. there is a ring that is built into the barrel that acts as a buffer between the hop up unit and the spring the problem is that this ring doesn't move so when I installed in it left no room for the hop up unit to spring back and forth like its suppose to. Anyone with experience with m14 barrels please any suggestions are welcome I'm hoping to not have to send the barrel back.
thanks
Derek.

Could you possibly take a picture of the problem? From my experience, the spacer ring should be able to push into the end of the hop up unit. I haven't used/dealt with a barrel that has the spacer built in, so I don't entirely know.

I might be able to get an idea with a picture though.
