UTG 3-Slot Super Slim Picatinny Riser Mount, BH 21 mm

• 21 mm saddle height: Raises a red dot or other Picatinny-mounted optic to a higher sight line, helping achieve a more natural head position and easier alignment on platforms that need extra clearance.
• 3-slot Picatinny platform: Provides enough rail space for many compact optics and accessories while keeping the mount short, which helps preserve room on crowded top rails.
• Super slim profile: The low-bulk body reduces added weight and avoids unnecessary width, making the rifle or carbine easier to handle without a bulky riser getting in the way.
• Square integral recoil stops and Torx screw clamp: The mount is built to stay firmly in place under recoil, supporting repeatable zero retention and reducing the chance of movement after hard use.
• 6061-T6 aluminum construction: The anodized aluminum body balances strength and low weight, giving the riser the durability needed for regular field or range use without adding much mass.

About the UTG Mounts Series

UTG Mounts covers a broad range of optic-mounting solutions for shooters who need practical, robust interfaces between their firearm and sighting system. Within this family, the Accu-Sync line focuses on Picatinny mounts and rings designed around secure engagement, repeatable positioning, and streamlined external shapes that do not add unnecessary bulk. The series includes cantilever mounts and scope rings for 1-inch, 30 mm, and 34 mm optics, along with multiple height and offset configurations to suit different rifles, carbines, and optic setups.

A defining trait of the series is its emphasis on mechanical simplicity paired with field-friendly details. Depending on the model, UTG Mounts may use locking levers or screw-fastened clamping systems, often combined with squared recoil stops to improve stability under recoil. The design approach favors compact dimensions, clean rail indexing, and mounting geometries that help users match optic height to stock comb, rail layout, and intended shooting position. In practice, that makes the series relevant for everything from hunting optics and sporting rifles to tactical carbines and general-purpose range setups where a dependable Picatinny interface matters as much as the optic itself.

About the UTG 3-Slot Super Slim Picatinny Riser Mount, BH 21 mm

The UTG 3-Slot Super Slim Picatinny Riser Mount, BH 21 mm is a compact riser for shooters who need a modest increase in optic height without giving up valuable rail space. Its 21.00 mm saddle height is well suited to red dot sights, magnifiers, and other compact Picatinny-mounted accessories that benefit from a slightly elevated mounting position. On rifles and carbines, that extra height can improve cheek weld consistency, clear handguard or rear-sight interference, and create a more comfortable upright shooting posture.

This model uses a 3-slot Picatinny top section, which keeps the mount short at 40.00 mm while still accommodating many compact optics. That short footprint is particularly useful on firearms where rail space is shared with backup sights, night vision bridges, or magnifier mounts. The super slim body shape and lightening cuts help keep the setup trim, so the riser adds function without making the top rail feel crowded or top-heavy.

Mechanically, the mount is designed for secure attachment and repeatable positioning. Its integral recoil stops and locking Torx screw interface help the riser stay planted under recoil, which matters when maintaining zero and avoiding shift after repeated removal or hard use. The aluminium construction and black anodized finish support everyday durability, while the 0 MOA configuration keeps the optic level with the bore axis, making it a straightforward choice for general-purpose red dot sight setups.
