This assembled .750 low-profile gas block and stainless gas tube combo is a drop-in pairing for AR-15 builds running .750-diameter barrel journals. The gas block is black-nitride-finished steel with set screws and roll pin pre-installed; the gas tube is a beveled stainless tube ready to slot directly into the upper receiver.
What's in the combo:
Install notes: The gas tube is press-fit on assembly with the supplied roll pin — verify alignment so the tube clears your handguard's gas-tube cutout before torquing set screws to spec (typical 35–45 in-lb with a drop of thread locker). Save the time of pinning the tube separately on the bench.
May ship with cosmetic blemishes on the gas block that do not affect fit or function. Gas length ships per variant — confirm the gas-port location on your barrel before install.
