DD 1 O'Clock Offset Rail BLK - Tactical Mount Accessory

The Daniel Defense 1 O'Clock Offset Rail is a lightweight tactical mount that clamps directly to your rifle's handguard side rail, enabling fast transitions between your primary optic and a secondary red dot sight positioned at the 1 o'clock or 11 o'clock position. Built for shooters who need to move seamlessly from long-range precision shooting to close-quarters work without losing their cheekweld, this offset rail lets you keep both eyes in the fight while switching between magnified and non-magnified aiming solutions in seconds.

Precision-machined from 6061-T6 aluminum billet and finished with mil-spec Type III hardcoat anodize, the mount is designed to be durable without adding bulk to your handguard. The integrated viewing tunnel minimizes sight picture obstruction and keeps your peripheral awareness sharp. Because it uses a standard MIL-STD-1913 Picatinny interface, the offset rail isn't limited to red dots—mount a laser, weaponlight, or other tactical accessories on the underside of your handguard for intuitive control with your support hand.

The 1 O'Clock Offset Rail now incorporates Daniel Defense's patented Rock and Lock one-piece mounting system, which streamlines installation, improves repeatability, and creates a more robust mounting surface. If you run a modern tactical rifle platform with a Picatinny rail, this mount solves the real-world problem of reaching secondary optics and accessories without fumbling or breaking position.

Specifications

Frequently Asked Questions

What rifles does the DD 1 O'Clock Offset Rail fit?

The mount attaches to any rifle handguard equipped with a MIL-STD-1913 Picatinny rail on the side. It clamps directly to the rail, so compatibility depends on your handguard's rail placement and profile, not your rifle's caliber or platform.

Can I mount both a red dot and my primary scope at the same time?

Yes. The offset rail positions a secondary optic or accessory to the side and slightly forward on your handguard, allowing you to keep your primary magnified optic on top while adding a non-magnified sight for close-range work without interference.

What can I mount on this rail besides a red dot?

The standard Picatinny interface accepts any compatible accessory—red dots, lasers, weaponlights, or other tactical gear. Many shooters use it on the underside of the handguard to position a light or laser near the forend grip for easy thumb operation.

Is the Rock and Lock mounting system proprietary to Daniel Defense rifles?

No. The Rock and Lock system is integrated into this mount and works with any MIL-STD-1913 Picatinny rail, so you're not locked into Daniel Defense handguards or uppers.
