The Most Honest Kinetic Development Group OPMOD Sidelok Aimpoint ACRO Mount Review Online
After years spent in environments ranging from dusty workshop benches to unforgiving outdoor expeditions and sterile laboratory settings, I’ve developed a keen eye for what truly works. When the need arose to securely mount an Aimpoint ACRO optic onto firearms where a low profile was paramount, and quick detach functionality was a non-negotiable, the Kinetic Development Group OPMOD Sidelok Aimpoint ACRO Mount immediately caught my attention. This specific mount, an exclusive offering for OPMOD, promised a blend of robust construction and user-friendly innovation that frankly, sounded too good to pass up.
The scenario that pushed me towards seeking out a dedicated ACRO mount like this was a project involving a lightweight PCC (Pistol Caliber Carbine) build. Traditional QD mounts, while effective, often added unnecessary bulk and weight, detracting from the firearm’s intended agility. Moreover, the need to quickly dismount the optic for cleaning or to utilize backup iron sights under specific conditions, without a frustrating wrestling match, became a recurring pain point. I needed something faster and more streamlined than a standard screw-tightened setup.
My initial impression upon handling this OPMOD-branded mount was one of solid engineering. The billet 6061 aluminum construction felt substantial yet surprisingly light, exactly as advertised. The anodized finish exuded a professional matte black look that promised durability and resistance to the nicks and scratches that inevitably come with real-world use. It felt precise, with no perceptible wiggle or play in its moving parts, hinting at the repeatable return-to-zero claims.
I briefly considered other quick-detach solutions, including some with elaborate lever systems, but many seemed overly complex or bulky for the low-profile goal I had in mind. The simplicity of the Sidelok mechanism, as described, offered a compelling alternative, promising tool-less operation. The immediate feeling was one of quiet confidence, a sense that this mount might finally solve the specific problem I was facing with optic mounting.
First Use Experience
My initial testing grounds for this optic mount were primarily focused on a Ruger PC Carbine chambered in 9mm. The goal was to see how the mount integrated with the firearm and the Aimpoint ACRO P-1, experiencing its core function of attachment and detachment firsthand. I mounted it on the Picatinny rail, familiarizing myself with the Sidelok mechanism’s operation, noting its smooth yet firm engagement.
In terms of performance, the mount excelled in its primary function: providing a rock-solid platform for the optic. Even after repeated cycles of removing and remounting the optic, the zero held remarkably well, a critical aspect for any serious optic mount. The mount’s low profile was immediately noticeable, significantly reducing the optic’s height over bore, which was precisely the design intent.
Ease of use was, frankly, exceptional. The one-handed operation, even with gloves on, was not an exaggeration. The Sidelok engaged and disengaged with a satisfying click and minimal effort, a stark contrast to the fiddly screws or levers I’d dealt with previously. There were no immediate surprises or quirks; it performed precisely as advertised, which in my experience, is a rarity.
Extended Use & Reliability
After several months of consistent use, including range days, training sessions, and general handling, the Kinetic Development Group OPMOD Sidelok Aimpoint ACRO Mount has proven its mettle. It’s become a fixture on my preferred PCC, experiencing countless cycles of attachment and detachment without any degradation in its performance or holding power. The low-profile setup has become indispensable for certain firearms where space is a premium.
Durability has been impressive. Despite being removed and reattached numerous times, the locking mechanism remains tight, and the billet aluminum shows only minor cosmetic scuffs from being handled. There are no signs of cracks, stiffness in the mechanism, or any hint of a performance drop, which speaks volumes about its robust construction and materials.
Maintenance is practically non-existent, which is a huge plus. A quick wipe-down with a dry cloth is all that’s ever been needed to keep it clean and functioning optimally. Unlike some other QD mounts that require occasional lubrication or tension adjustments, this unit remains a “set it and forget it” component, only needing to be touched when the optic itself needs to be removed. Compared to older, more complex QD systems I’ve used, this mount requires significantly less upkeep.
Specifications
The Kinetic Development Group OPMOD Sidelok Aimpoint ACRO Mount is crafted from high-strength billet 6061 aluminum, ensuring a superb strength-to-weight ratio. This material choice is crucial for a component that needs to be both durable and lightweight, contributing to its stated approximate weight of 2.5 oz. The mount features a black anodized finish, providing excellent corrosion resistance and a non-reflective surface crucial for tactical applications.
This mount offers a low profile design, specifically engineered to minimize the optic’s height above the firearm’s mounting surface. It is compatible with Aimpoint ACRO Red Dots or other compatible Red dots utilizing an ACRO style mounting base. A key characteristic highlighted in its design is its no co-witness capability, which is ideal for platforms where absolute cowitness is not a requirement or is actively undesirable.
The Sidelok mechanism is the star here, allowing for instant attachment or detachment of the optic to the firearm. This is achieved with no tools or adjustments needed, facilitating one-handed operation even while wearing gloves. Critically, it offers 100% repeatable return to zero, meaning you can remove and reattach the optic multiple times with confidence that it will return to its original point of aim.
Performance & Functionality
In its core function, the Kinetic Development Group OPMOD Sidelok Aimpoint ACRO Mount performs exceptionally well. It securely locks an Aimpoint ACRO optic (or compatible footprint) to a Picatinny rail with impressive rigidity. The Sidelok mechanism’s primary job is to facilitate rapid optic changes, and it absolutely nails this aspect, making it faster than any screw-based mount I’ve encountered.
The main strength lies in its speed and ease of use. The ability to detach and reattach the optic with one hand, without tools, and with consistent return to zero, is a game-changer for certain firearms and scenarios. Its weakness, if one could call it that, is its intentional design choice to not offer co-witness with AR-15 style iron sights, which is a deliberate trade-off for its low-profile nature.
Overall, this mount exceeds expectations for its intended purpose. It delivers on its promise of rapid, tool-less optic changes while maintaining zero, making it an outstanding choice for firearms where a low profile and quick optic swaps are beneficial. It performs its specific function reliably and efficiently, which is all one can ask for in a dedicated mounting solution.
