Forward Controls Design (FCD) — Precision Optic Mounting Plates

Forward Controls Design (FCD) makes optic mounting plates and accessories for pistols with one guiding principle: the best solution, not the cheapest. While most optic plate manufacturers use aluminum — including 7075, the strongest aluminum alloy — FCD machines their plates from 4140 steel and 17-4 stainless steel, arguing that no aluminum alloy is adequate for the recoil forces generated in a firing pistol. This isn't marketing — it's a deliberate engineering position that FCD backs with technical reasoning, and it's why serious competition and duty shooters seek out FCD plates specifically.

The Engineering Case for Steel

A 1.2oz RMR weighs 112.5lb at 1500G of recoil. FCD does not believe aluminum is a suitable material for anything that can experience up to 1800G of recoil — especially for sights that use a cross bolt. 4140 steel costs more and takes longer to machine, but FCD considers reliability and durability far more useful qualities than light weight in this application. The result: OPF plates that hold the optic genuinely immobile in recoil, eliminating the screw loosening and shearing failures that plague lesser plates under sustained fire.

The OPF Line — Optic Platform, Forward Controls

FCD's optic plate lineup is called the OPF (Optics Platform, Forward Controls) line. Every OPF plate uses the same design philosophy: front and rear recoil fences that sandwich the optic body, tight tolerances (held to 0.003"), and steel-on-steel construction. Plates ship with Vibra-Tite VC-3 thread compound and Torx hardware. A torque wrench is required for proper installation.

Glock MOS (Gen 3-5 and Gen 6 ORS)

  • OPF-G, RMR — for Trijicon RMR and SRO on Glock MOS. The original FCD plate, developed in collaboration with USMC combat veteran and former USMC Shooting Team head coach Tom Shields. Machined in 4140 steel, black nitride coated.
  • OPF-G6, RMR — for Glock Gen 6 ORS slides. Machined in 17-4 stainless steel — standard on all Gen 6 compatible plates. Requires a sealing plate for RMR (not required for RMR HD, SRO, or RCR).
  • OPF-G, ACRO — for Aimpoint ACRO on Glock MOS. A collaboration with Tangodown (AAM-01). Machined in 4140 steel, Melonite coated.
  • OPF-G, DPP — for Leupold DeltaPoint Pro on Glock MOS. A collaboration with Tangodown. 4140 steel.
  • OPF-G, EFLX — for EOTech EFLX on Glock MOS. Also compatible with DeltaPoint Pro (note: use correct screws for each optic).
  • OPF-G, RMRcc — for Trijicon RMRcc on Glock MOS (Gen 3-5 full size and compact, not compatible with 43X/48).

Sig Sauer P320

  • OPF-M17, ACRO RSD — for Sig P320 M17/M18/Legion/AXG with dovetail rear sight. Aimpoint ACRO P1/P2 compatible. Machined in 4140 steel, QPQ coated. Collaboration with Tangodown.

Walther PDP

  • OPF-PDP v2, ACRO — for Walther PDP v2 and Aimpoint ACRO P1/P2 (also compatible with Steiner MPS). 4140 steel, black nitride. Not compatible with PDP v1. Collaboration with Tangodown.

FCD Accessories

  • SBT Battery Tool — for Trijicon RMR HD and SRO. Machined in 17-4 stainless steel. A collaboration between FCD and FischerPrecision3D. Designed for use with a 1/4" bit screwdriver or included handle.

FCD's Collaboration Philosophy

FCD is a small company that only takes on projects where they can genuinely improve on what exists. When a product already exists that they couldn't do better — like the Tangodown ACRO plate for Glock MOS — they collaborate and co-brand rather than create a duplicate. This philosophy means every FCD product represents a deliberate engineering decision, not a catalog expansion for its own sake.
