BCM C8 SFW barrel. This is the BCM made 16″ clone of a Colt Canada / Diemaco Canadian C8A3 or British L119A1 barrel used in the Commonwealth SAS and SBS service.
Includes factory installed flash hider, SIMON grenade sleeve, triangle front sight, barrel nut, and delta ring assembly.
This is the closest barrel any normal person will come to owning a real Colt Canada SFW barrel. This barrel is compatible with Colt Canada / Diemaco flattop uppers provided they have M4 feedramps, if you are building a clone.
