Outer barrel length inquiry
 

Im pretty much finished working on my C8 (just waiting for mags). The only thing I'm curious about is the outer barrel length I'll need to bring a suppressor flush (or close) to my hand guard.

I'm currently running a Madbull DD MK18 RIS II rail with my standard G&P M4 14.5 inch outer barrel. What length of barrel will bring my suppressor flush to my RIS?

If anyone has any input or pics, it'd be greatly appreciated :)

10.5"

Sounds good! Thanks!
