How Does the DLOC Clamp System Work?

The patented DLOC system uses precision press-fit steel pins for recoil lugs and spring-loaded clamping side bars. Each clamp section of the mount contains two steel pins that pass completely through both the Picatinny rail and the locking bar. This allows the locking bar to slide in and out—under spring pressure—while staying perfectly square.

At the center of each clamp section is a tension knob that also passes completely through the Picatinny rail. Our cantilever scope mounts feature two clamp sections, meaning a total of six steel recoil lugs for unmatched holding strength. Thanks to this design, DLOC mounts maintain a rock-solid grip on the rail, even if the rail is slightly over or under the MIL-STD-1913 specification.

While the design may sound complex, installing or removing a DLOC Precision mount is actually simpler than with most quick-detach mounts on the market—and best of all, no tools are required.

Installation

• Loosen the tension knobs (thumb screws) by hand until you feel a hard stop.
• Push in on the knobs; the locking bars will expand.
• With the knobs depressed and the mount expanded, set the mount into the desired rail slot and release the tension.
• Tighten the tension knobs by hand until snug.

Removal

• Loosen the tension knobs completely until you feel the hard stop.
• Push in on the knobs to expand the mount.
• Lift the optic and mount straight up and away from the rail.

Unlike other QD mounts, the DLOC system has no rotating locking lever or locking arm. One reason the DLOC design is exceptionally strong—and the most repeatable mount on the market—is that it relies on straight-line motion rather than rotational motion to lock onto the rail. Rotating designs typically concentrate clamping force unevenly at a single point. In contrast, DLOC’s full-length locking bar applies even tension across a large section of the rail. This locking bar also slides in and out on precision press-fit recoil lugs, ensuring it remains perfectly square at any level of tension.
