Gas Ring, Helical (One Piece AR-15 Gas Ring)

Description

Single spiral of 300 series stainless steel wire with polished outer diameter for your AR-15 style bolt. These provide improved gas seal between bolt and expansion chamber inside the carrier. This helical wire ring replaces conventional three-piece “piston ring”style and provides longer gas ring lifespan when used on Titanium products versus legacy/mil-spec stamped steel conventional gas rings. *PLEASE NOTE* ALL RCA Titanium Complete BCGs ship with a one piece gas ring pre-installed.
