OPF-G ACRO Glock MOS Optic Plate
The OPF-G ACRO (Optics Platform, Glock, for ACRO) is a Glock MOS Adapter Set 01 compatible plate for mounting Aimpoint ACRO P1 and P2 and Steiner MPS optics on Glock Gen 4 and Gen 5 slides. It fits the G17, G19, G34, G35, G41 at 25mm width, and G40.
Why Steel Instead of Aluminum
Most Glock optic plates on the market are machined from aluminum. Forward Controls Design does not make aluminum plates, and the reason is straightforward: an optic plate is a structural interface that absorbs every recoil impulse the slide produces, and it carries threaded holes that a red dot is torqued into.
Aluminum threads are the first thing to fail under that load. Once the threads deform, the optic loosens, and a loose optic is a zero you cannot trust. The OPF-G ACRO is machined from 4140 steel and Melonite coated.
What Makes a Duty Grade Optic Plate
Forward Controls Design spends longer in development than most companies spend on an entire product line. Material selection is deliberate and excludes anything that cannot survive duty use. Every material is sourced in the United States, and their plates are designed, developed, and manufactured here.
They work directly with their manufacturers rather than sending a drawing and hoping. They hold extremely tight tolerances, run stringent quality control, and test exhaustively before a product ships. Nothing goes to market to be beta tested by customers.
On the MOS System
The alternative to MOS is sending a slide out to be milled, or buying a third party optics ready slide. Beyond the wait and the variable quality of milling work, there is no standard sight height across shops. Two slides milled by two different shops sharing a sight height would be a coincidence.
MOS may not sit as low as a milled slide, but uniform sight height, ease of installation, and parts commonality more than make up for it. The weak point of the system has always been the factory adapter plates, which is what this replaces.
Running a Gen 6 Glock instead? See the OPF-G6 ACRO plate for Gen 6 ORS slides. Running a Trijicon optic? See the OPF-G RMR plate for RMR and SRO.
