American Defense Aimpoint T1 LW QD Mount - Lower 1/3 Co-Witness, Quick Release
American Defense
The Daniel Defense Aimpoint Micro Mount with Rock Lock system is a lightweight, durable mounting solution built for shooters running Aimpoint Micro optics—the R-1, H-1, T-1, or T-2—on AR-platform rifles and other Picatinny-railed firearms. If you're after a permanent, low-profile mount that won't add unnecessary weight or bulk, and you want the flexibility to set your sight picture to absolute or lower 1/3 co-witness with your backup irons, this is the mount to consider. Daniel Defense engineered this design around the essentials: secure retention, repeatable zero, and no snags or sharp edges.
The core innovation here is the recoil lug interface—a feature that directly addresses one of the weak points in other mounting schemes. Rather than letting recoil energy travel down the fasteners and into the optic's factory mounting threads, the recoil lug absorbs and redirects that energy, keeping your zero rock-solid shot after shot and extending the life of your optic. That's not marketing speak; it's mechanical durability. The Rock Lock attachment system secures to any MIL-STD-1913 Picatinny rail with two slotted machine screws that thread into stainless steel self-locking inserts—they resist vibration loosening without requiring threadlocker or constant maintenance.
Switching between absolute co-witness and lower 1/3 co-witness is straightforward: include the spacer with your installation for 1/3 height, or omit it for absolute co-witness with your irons. The mount is reversible and free of unnecessary snags or protrusions, so it plays well with slings, cases, and rough handling. If you've been comparing lightweight Aimpoint Micro mounts, the Daniel Defense version has earned its reputation for combining minimal weight with maximum reliability—no quick-detach complexity, just a solid, fixed platform that holds zero.
