Daniel Defense 30mm Optic Mount, Double Ring

Product Description

The Daniel Defense 30mm Optic Mount, Double Ring, part number 03-047-07195, is a double-ring one-piece optics mount for standard-size variable power scopes with a 30mm main tube, precision machined from aerospace grade aluminium, finished in Type III hard coat anodising, weighing 5.5 ounces and mounting by way of Daniel Defense’s patented Rock & Lock mounting technology.

Tube diameter is the whole decision here. Daniel Defense offers this variable power scope mount line in 1 inch and 30mm tube sizes, and this part number is the 30mm version. If your scope has a 1 inch tube, the 1 inch double ring mount is a separate part number and that is the one you need. There is no adapter or workaround that makes a 30mm ring set hold a 1 inch tube properly, and trying it damages scopes.

Beyond diameter, the argument for a one-piece double ring mount over two separate rings is alignment. A single machined body holds both rings in the same bore, so ring lapping and the slow misalignment of two independently clamped rings stop being your problem. The trade-off is that ring spacing is fixed, so an unusually short scope body may not suit it.

30mm or 1 inch: getting the fitment right

Daniel Defense builds this mount in two tube sizes, and this part number is the 30mm one. The practical test is simple: check the scope’s main tube diameter, not its objective or eyepiece diameter. If the tube measures 30mm, this is your mount. If it measures 1 inch, order the 1 inch double ring mount instead. If it is 34mm or 35mm, neither of these two fits and you need a different mount entirely — call 817-393-4000. Our scope rings and mounts and scope mounts pages list the alternatives, and the Daniel Defense category collects the brand’s optics hardware.

Installation and levelling

The mount uses Torx Plus fasteners for easy installation and removal. Get the correct driver: Torx Plus and standard Torx are similar enough to engage and different enough to round a fastener under torque. Ring cap screws want even, alternating tightening in small increments so the scope body is not pulled sideways. Confirm torque figures rather than assuming them.

Frequently Asked Questions

Q: What tube diameter does the Daniel Defense double ring optic mount fit?

A: This part number, 03-047-07195, is the 30mm version and fits scopes with a 30mm main tube only. Daniel Defense offers this mount line in 1 inch and 30mm tube sizes, so the 1 inch version is a separate part number. The two are not interchangeable.

Q: Will this 30mm mount work on a 1 inch scope tube with an insert?

A: No. Do not attempt it. The rings are machined for a 30mm tube, and shimming a 1 inch tube inside 30mm rings puts uneven pressure on the tube, which is how scopes get crushed. Daniel Defense builds a 1 inch version as its own part number; order that instead.

Q: How much does the Daniel Defense 30mm double ring mount weigh?

A: The mount weighs 5.5 ounces. Daniel Defense builds these variable power scope mounts at just 5.5 ounces, which is competitive for a one-piece double ring mount in aerospace grade aluminium. On a carbine already carrying a light and a sling, a known figure beats a vague claim about being lightweight.

Q: What is Rock & Lock mounting technology on a scope mount?

A: Rock & Lock is Daniel Defense’s patented mounting technology, used across its rail-mounted accessory line and on this mount. It is how the mount interfaces with the rifle’s rail. For the correct installation sequence and fastener torque on your upper, call 817-393-4000 rather than a generic instruction card.

Q: What tools do I need to install this mount?

A: The mount uses Torx Plus fasteners for easy installation and removal. Torx Plus is not the same as standard Torx, so the right driver matters if you do not want to round out a fastener. Confirm the exact bit size with us on 817-393-4000, or have our gunsmith mount the optic.

Q: Is this mount made in the USA?

A: Yes. This 30mm optics mount is manufactured in the USA, precision machined from aerospace grade aluminium and finished in Type III hard coat anodising. That grade of hard anodising is the reason a mount like this survives being clamped, unclamped and re-torqued repeatedly without the surfaces wearing through.
