Trying to find the perfect mounting height for your rifle’s red dot sight shouldn’t feel like a high-stakes guessing game. Yet, the modern shooter is forced to make a permanent choice upfront: do you buy a traditional lower-third mount for a classic cheek weld, or do you commit to a tall, ultra-high riser optimized for night vision and a fast, heads-up posture?
If you guess wrong, your only option is to throw that expensive piece of aluminum into your spare parts bin and buy an entirely new mount.
At KDG, we don’t follow the market. We build what it’s missing.
The KDG BOM Series Red Dot Mount completely rewrites the playbook on optic risers. Engineered for mission-critical reliability, this modular hard-mount system delivers a bomb-proof, permanent rail interface alongside adjustable height versatility right out of the box. Whether you run an industry-standard Micro footprint or an enclosed mail-slot optic, the BOM series ensures you never have to buy another riser to adapt your rifle to changing mission profiles.
Speed vs. Security: Why Choose a Red Dot Hard Mount?
Quick Detach (QD) mounting systems are incredible for accessories you want to hot-swap or remove on the fly. But when it comes to your primary sighting system on a duty weapon, home-defense carbine, or hard-use trunk gun, absolute security overrides convenience.
A dedicated hard mount is the professional standard for anything that simply cannot fail under pressure. By removing tool-less levers and spring-loaded buttons, a premium hard mount relies on high-torque mechanical tension to establish a semi-permanent bond with your upper receiver.
The BOM Series Red Dot Mount is built on this “set-it-and-forget-it” philosophy. It handles extreme directional impacts, rapid temperature swings, and violent recoil profiles without shifting your zero by a fraction of an MOA.
Introducing the BOM Modular Height Advantage
The defining flaw of standard hard mounts is their total lack of adaptability. The BOM Series fixes this by utilizing an innovative, tiered riser system that changes heights seamlessly without sacrificing structural strength.
+-------------------------------------------------------------+
| THE BOM MODULAR HEIGHT ECOSYSTEM |
+-------------------------------------------------------------+
| [Base Profile] --> 1.57" Height (Lower 1/3) |
| [With Riser Blocks] --> 1.93" Height (Heads-Up / NV) |
+-------------------------------------------------------------+
Instead of cluttering your workbench with multiple mounts, the BOM series provides multiple height options in a single package. You can configure your optic lower to the rail for traditional carbine classes, or raise it up instantly to clear top-mounted laser aiming modules (LAMs) and optimize your rifle for passive shooting under night vision goggles.
Key Features of the KDG BOM Red Dot Mount
Every millimeter of this mount has been refined to eliminate weak points and provide an unyielding foundation for your electronic optics.
1. Two Primary Heights in One Box
We don’t believe in forcing you to buy extra parts later. Out of the box, the base mount sits at a crisp 1.57″ height, placing your red dot at the preferred lower-third co-witness level for standard iron sights. Need a more vertical posture to prevent neck fatigue or clear a weapon light switch? Simply insert the included lift blocks, drop in the extended hardware set, and you are immediately configured for a 1.93″ heads-up stance.
2. Steel-Clamped Hybrid Construction
An optic mount is only as strong as its connection to the rail. While an all-aluminum rail interface can degrade or strip under extreme stress, the BOM uses an intentional hybrid material layout. The main body is precision-machined from lightweight aerospace-grade aluminum to keep your platform balanced, while the independent cross-bolts and clamping blocks are forged from high-strength steel. This provides a uniform, heavy-duty clamp across your 1913 Picatinny rail that won’t distort over time.
3. Precision Footprint Compatibility
The BOM series is tailored to support the world’s most trusted duty optics. Available in industry-standard mounting footprints, it mates flawlessly with:
- Aimpoint Micro Footprint: Fits Aimpoint T1/T2/H2, Holosun 403/503 series, Primary Arms micro dots, and Sig Sauer Romeo4/5 optics.
- Aimpoint ACRO Footprint: Designed specifically for the unyielding cross-bolt design of enclosed emitter sights like the ACRO P1/P2 and Steiner MPS.
- Aimpoint COA Footprint: Engineered to securely integrate Aimpoint’s low-profile, enclosed-emitter COA standard using its dedicated lockup design.
- Trijicon RMR Footprint: The industry standard for full-size pistol optics, fitting the Trijicon RMR/SRO/RCR, Holosun 407C/507C/508T, and Swampfox Liberty/Justice.
4. Low-Profile, Snag-Free Geometry
A piece of duty gear should never create secondary hazards on your rifle. The BOM features radiused, chamfered edges and a completely streamlined profile. There are no oversized dials, clumsy levers, or aggressive edges to snag on your tactical sling, clothing, vehicle upholstery, or environmental barriers when deploying under stress.
