天鵝頸

The M10 x 1.0 thread screwed right into my gun with no cross-threading, which was my main worry. I went with the flexible version and it lets me get into tight corners way easier than the old fixed neck. Solid build, no wobble at all.

Swapped this rigid neck onto my 15 series gun and the M10 x 1.0 thread screwed in clean with no cross-threading. Liner feeds smooth through it now, and the neck holds its angle instead of drooping mid-weld.

Picked up the flexible swan neck version and it's made reaching tight corner welds way easier than the rigid setup I had before. The bend holds its position without sagging, which is exactly what I needed.
