Piecing together some ideas for a build and I was wondering if there are any options that someone knows of to get a 20" outer barrel on a WE M4.
I know about the WA to WE outer barrel adapter, but I want to make sure that there aren't any alternative options first.
Out of curiosity, would I be able to use a PTW outer barrel such as this?
