Airsoft Canada - View Single Post - What's the use of that little metal ring around the inner barrel?

It's past the hop-up unit. It's thin and about 2mm long.

I don't recall ever seeing one on my TM M4A1. But there was one on my CA G36K. I changed for a Systema tight bore, and now the ring doesn't fit on the outer diameter of the new inner barrel.
