Most optic mounts force you to make a permanent decision before you even open the box. You have to guess whether you want a lower-third co-witness or a tall, heads-up posture. You have to commit to one specific red dot footprint. If you decide to change your optic setup six months from now, your expensive mount becomes a paperweight, and you are back to square one.
We looked at a drawer full of single-use, abandoned optic mounts and decided the market was missing a smarter alternative.
While our Sidelok line remains the king of Quick Detach modularity, we knew a subset of shooters demanded a dedicated, bombproof hard mount—but still wanted the freedom to adapt. Enter the KDG BOM Series. It is a permanent, bolt-on fortress for your red dot that completely future-proofs your rifle.
THE HARD MOUNT PARADIGM: ZERO COMPROMISE
The BOM Series is engineered for shooters who prefer a set-it-and-forget-it solution. Whether your rifle is going in a patrol car, a rugged gear bag, or surviving the heavy, violent recoil of large-caliber platforms, this mount is designed to withstand extreme abuse without shifting your zero by a fraction of a millimeter.
But “fixed” shouldn’t mean “limited.” We infused the BOM with a level of modularity never before seen in a rigid bolt-on mount.
TWO HEIGHTS. ONE BOX.
Stop buying multiple mounts just to figure out your preferred sight picture. The BOM system solves the elevation dilemma by including everything you need for the two most demanded heights in the industry right inside the box.
- 1.57″ Lower-Third Co-Witness: Run the mount clean out of the box for a traditional, reliable cheek weld that aligns perfectly with standard backup iron sights.
- 1.93″ Heads-Up Height: Use the included lift block and long hardware set to raise your optic. This configuration is optimal for keeping a more upright posture, shooting comfortably while wearing gas masks, or passive aiming through night vision goggles.
You don’t need to choose at the checkout counter. Test both configurations on your own rifle and see what works best for your specific workflow.
FUTURE-PROOF YOUR FOOTPRINT
The industry changes fast, and the optic you run today might not be the optic you want tomorrow. Instead of locking you into a single ecosystem, the BOM Series utilizes a brilliant interchangeable top-plate system.
If you switch from a closed-emitter mailslot to a micro reflex sight, you don’t throw away the mount. You simply swap the top plate. At launch, the BOM supports four of the most prolific industry footprints and a new one:
Supported Interfaces: Aimpoint T2 // Trijicon RMR // Aimpoint ACRO // Leupold DPP // Aimpoint COA
HYBRID ENGINEERING: ALUMINUM SURVIVABILITY, STEEL GRIP
We didn’t just machine a block of metal and call it a day. The BOM features an intentional hybrid construction that puts the right materials exactly where they belong.
The main body and riser blocks are precision-machined from high-grade aluminum to keep your weapon system as lightweight and nimble as possible. However, aluminum is not ideal for the extreme friction of a rail clamp. That is why the mounting crossbolt and side clamp are crafted from high-strength steel. This creates a vice-like, unyielding grip on your 1913 Picatinny rail that can handle severe impact and constant vibration.
