Lol So you think buying 2 guns is easier than putting a rail onto the gun you already have?
The KJW is TM compat, the WE not so much, the we's slide might not fit onto the rails on the kjw without some sanding/filing OR it might be too wide and ride sloppily on the rails
The WE's outer barrel system might also be an issue, so may have to use the KJW's outer barrel, leading to further issues
