Description
A heavy-duty stainless steel optic plate that mounts an Aimpoint ACRO P-2 or Steiner MPS on Glock Gen 6 ORS slides.
The OPF-G6, ACRO replaces the polymer insert of the Glock Gen 6 Optic Ready System with a plate milled from solid 17-4 stainless steel. It uses the entire ORS pocket to index: the underside is contoured to fill the spindle-shaped cavity and a relief at the rear engages the slide's locking tab, so the plate cannot rotate or shift.
The ACRO dovetail is kept to Aimpoint's specification rather than shortened to lower the sight, so the sight stays put on the plate. Because the plate must accommodate the countersink of the M4 screws used by the Gen 6 slide, the top of the dovetail sits above the slide.
Key features
- 17-4 stainless steel — Milled from solid 17-4 stainless and black nitride treated; standard on all OPF-G6 plates.
- In-spec ACRO dovetail — Dovetail height follows Aimpoint's ACRO specification for full sight retention; it also seats the Steiner MPS properly.
- Uses the ORS locking features — Contoured underside and rear relief engage the spindle cavity and rear locking tab of the Gen 6 slide.
- Standard M4 hardware — Uses US-made T20 M4-0.7 × 8 mm plate-to-slide screws rated at 140,000 PSI tensile strength, which are easy to source.
- Lightening cuts — Deep pockets on the underside reduce weight and are hidden once installed.
Compatibility and fitment
- For Glock Gen 6 slides with the Optic Ready System (ORS).
- Sights: tested with and supported for the Aimpoint ACRO P-2 and Steiner MPS. Fit and function are not guaranteed for Chinese-made ACRO-footprint sights.
- Backup sights: the ACRO P-2 needs a front sight height of at least 0.385 in, which gives a lower 1/4 co-witness. A 0.365 in sight set is sufficient for the Steiner MPS.
- Holsters: compatible with most duty holsters made for the Gen 6 MOS, such as the Safariland 6360. It is compatible with the TangoDown Lens Guard, but not with the Safariland 6360 when a TangoDown Lens Guard is fitted to the P-2.
- Depending on slide tolerances, a gap of 0.001 to 0.002 in can appear at the front underside of the plate. It is cosmetic. Fine tool marks inside the lightening cuts are not visible once the plate is installed.
- Installation: insert the rear of the plate into the rear of the ORS pocket at an angle, confirm the slide's locking tab has engaged the pocket in the plate, then rotate the front down. A firm press on the front may be needed to seat the plate fully.
