RS Regulate BM-2 AK47/Yugo Spec (.66) Accessory Mount - Fits .66" Barrel Diameter, Matte Black Finish - BM-2 - 617395300303
Product Description
Mounting tactical flashlights or infrared illuminators to AK pattern platforms—specifically Yugo/Zastava models—has historically required replacing handguards with heavy, heat-retaining railed foreends or relying on flimsy barrel clamps that shift under recoil and alter point-of-impact. The RS Regulate BM-2 AK47/Yugo Spec Barrel Accessory Mount (BM-2) solves these mounting and weight challenges by delivering a ultra-lightweight, low-profile Picatinny rail section that clamps directly to 0.66" outer diameter barrel profiles with zero barrel deformation.
Precision CNC-machined from 6061-T6 aircraft-grade aluminum, the BM-2 features an 8-slot 1913 Picatinny rail positioned virtually flush to the barrel axis. This minimal-clearance profile places your weapon light directly adjacent to the handguard for easy thumb activation while preserving traditional wooden or polymer furniture configurations. Designed specifically for Yugo-spec barrels (such as the Zastava M70, M90, M77) and standard AKM/AK-47 barrel journals measuring 0.66 inches ahead of the gas block, the two-piece clamping mechanism distributes clamping pressure evenly without impacting barrel harmonics or sight picture.
Finished in a durable Type III hardcoat anodized matte black coating, the RS Regulate BM-2 weighs under one ounce, offering a rugged, ultra-clean illumination solution for AK purists and modern defensive rifle setups alike.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment & Measurement Matrix: Engineered specifically for barrels with a 0.66" (16.7mm) outer diameter forward of the gas block. Fits Yugo/Zastava AK pattern rifles (M70, M90, M77), standard AKM/AK-47 barrels, and platforms with matching 0.66" dimensions. Note: Always verify barrel diameter using calipers before installation. Will NOT fit heavy-profile barrels (e.g., VEPR, 0.59" light-profile AK-74 barrels, or 0.75" front sight blocks without checking BM-1 / BM-3 sizing options).
Installation & Torque Sequence:
- Safety check the rifle, remove the magazine, and visually and physically inspect the chamber to confirm a clear weapon.
- Clean and degrease the clamping area on the barrel forward of the gas block.
- Separate the BM-2 mount halves and position them around the barrel at the desired rotation angle for light placement (typically 9 o'clock or 3 o'clock).
- Apply a small drop of non-permanent blue threadlocker (Loctite 242) to the clamping screws.
- Tighten the screws evenly in an alternating cross pattern until snug, then torque using an inch-pound torque wrench to 10–12 in-lbs. Do NOT over-torque.
Key Features
- Engineered for 0.66" Barrel Profiles: Purpose-built to clamp securely onto Yugo/Zastava pattern AKs and standard AKM 0.66" barrel sections.
- Ultra-Low-Profile Picatinny Rail: Keeps mounted weapon lights tightly tucked against the handguard for low-bulk handling.
- Preserves Factory Handguards: Enables tactical light mounting while retaining classic wood, surplus, or modern non-railed handguards.
- 6061-T6 Aircraft Aluminum Construction: Delivers maximum rigidity and strength with a total weight under 1.0 ounce.
- Mil-Spec Type III Hardcoat Anodized Finish: Provides extreme surface hardness and corrosion resistance against harsh field conditions and muzzle blast.
- Non-Marring Clamping Geometry: Evenly distributes clamping forces across the barrel circumference without impairing accuracy.
