"Skinny" Tracer Unit

[Von Nimble]

Hello all,

I'm on the hunt for a "skinny" tracer unit. It is for my G&G Predator, anyone familiar with the gun know it's has that angry maw on the front (see pic).

That maw raises the issue if not being able to fit big suppressors on there. I am wanting to fit a Traver unit but I'm not able to find one which will fit so far. I have a mock suppressor on there already which has a diameter of 30MM and I wonder if anyone can point me I the direction of a tracer unit at that size?

Any help and advice would be appreciated! Thanks!

P.S. I'm steering away from the tracer unit hop-ups as I have heard they are a neat idea but a bit shoddy in practice.
