RA Tech Precision Inner Barrel help

[Coski]

Hey all.

Im looking at purchasing a tightbore for my WE 16 inch M4.

Obviously length wise, a standard M4 inner isn't going to cut it, so looking at getting the tightbore for the M14 Socom(410mm).

Does anyone know if the M14 inner barrel will fit the M4? Is their only difference in length or does it come down to how it fits in the hop as well?

Not sure, but I would google the hop unit and see if it looks remotely similar!
