8.6 Blackout Barrel

What this is

This is our house-spec 8.6 Blackout barrel, rather than a named third-party manufacturer’s product like the Faxon-branded barrel we also carry in this caliber. If brand, specific steel spec, or a particular surface treatment matters for your build, compare the two listings before ordering.

Confirm before ordering

Length and twist rate: 8.6 Blackout is loaded across a range of bullet weights from lighter supersonic projectiles up to heavy subsonic loads, and twist rate needs to match whichever weight range you plan to shoot most. Confirm thread pitch and whether a thread protector ships with it if you are planning a suppressed build.

Fitment

Confirm this barrel’s extension and headspace match your specific upper before ordering, an 8.6 Blackout barrel from one source is not automatically a drop-in fit on every 8.6 Blackout upper on the market.
