Atibal E2 – ACRO To RMSC Adapter Plate Review

First Impressions of Atibal E2 – ACRO To RMSC Adapter Plate

The Atibal E2 – ACRO To RMSC Adapter Plate promises a seamless solution for mounting the increasingly popular Aimpoint ACRO series of red dot sights onto firearms milled for the RMSc footprint. This small, black adapter plate opens up a world of possibilities for those seeking to upgrade their existing optics setup without the hassle of slide modifications. I was intrigued to see if it lived up to the hype.

My journey to this adapter started with a new pistol build featuring an RMSc cut slide. I’ve grown to love the ACRO’s enclosed emitter design for its unmatched durability and performance in adverse conditions. The problem? My preferred slide came only with an RMSc footprint. The Atibal E2 – ACRO To RMSC Adapter Plate appeared to be the perfect bridge between these two worlds.

Upon unboxing, the adapter plate felt solid and well-machined. The black finish was clean and even, suggesting a quality product. Its weight was negligible, which is a plus for maintaining the balance of the firearm.

Compared to other mounting solutions I’ve used, like direct milling (which wasn’t an option here) or thicker, universal adapter plates, the Atibal E2 – ACRO To RMSC Adapter Plate stood out for its slim profile. It seemed like a more elegant and less bulky way to achieve the desired optic mounting. I chose this adapter over a different brand’s offering because Atibal is known for quality and precise manufacturing. I was hoping this would ensure a tight, reliable fit.

My first impression was one of cautious optimism. The adapter plate looked promising, but the proof would be in the installation and performance. I was eager to see if this seemingly simple piece of metal could deliver on its promise of a rock-solid ACRO mount.

Real-World Testing: Putting Atibal E2 – ACRO To RMSC Adapter Plate to the Test

First Use Experience

My initial testing ground for the Atibal E2 – ACRO To RMSC Adapter Plate was the local shooting range. I mounted the adapter plate and an Aimpoint ACRO P-2 to my Glock 43X MOS. The installation was straightforward using the provided screws.

The weather was mild, but I intentionally subjected the setup to rapid firing and some simulated tactical drills. I wanted to see if the adapter plate would shift or loosen under stress. The adapter stayed firmly in place, maintaining zero throughout the initial 200 rounds. There were no noticeable issues or surprises after the first range session.

Extended Use & Reliability

After several months of regular use, including weekly range visits and even a weekend-long defensive pistol course, the Atibal E2 – ACRO To RMSC Adapter Plate has proven its reliability. There are no signs of loosening, and the ACRO remains securely mounted. The finish has held up well, with no noticeable wear and tear despite constant handling and holster use.

Maintenance has been minimal; a quick wipe-down with a cloth after each range session is all it takes. Compared to other adapter plates I’ve used in the past, this one requires significantly less attention. It has definitely outperformed my expectations. I originally thought I might have to regularly tighten the screws, but that hasn’t been the case.
