Will this fit my .750 barrel without any machining?
Yes — it’s sized for a standard .750″ gas block journal and drops right on, no fitting or machining needed.
What’s the set screw spacing on this gas block?
0.470″ center-to-center, matched to modern match-grade barrel patterns rather than older mil-spec spacing, so check your barrel’s screw spacing before ordering.
Does it come with the roll pin and set screws?
Yes, the roll pin and two 4140 steel set screws ship with the gas block — nothing extra to buy.
Will the low profile height clear my free-float handguard?
Yes, the low profile design is built to clear free-float M-LOK and Keymod handguards on a .750 build.
What finish is this gas block?
Bead-blasted 416 stainless steel with a silver finish that resists corrosion without needing a coating.
Does this include a gas tube?
No, this is gas block only — pair it with a properly sized gas tube for your barrel length.
