FMA AN/PEQ-16 Battery Case — Sand

The FMA battery case, a replica of the AN/PEQ-16, is a Picatinny rail-mounted housing for two CR123A batteries, designed for shooters who need a compact power solution integrated directly on the weapon. The internal compartment measures 90 x 45 x 20 mm and the centre section is removable, allowing batteries of different lengths to be accommodated without replacing the entire body.

The body profile follows the original AN/PEQ-16 geometry, with a concave upper surface: this recess lowers the accessory's centre of gravity relative to the rail, bringing the weapon body closer to the overall centre of mass. The practical result is reduced lateral bulk and less stress on the mounting point during recoil, compared to a flat-profile housing mounted at the same height.

Attachment is via MIL-STD-1913 connection: the mount fits any standard Picatinny rail on a rifle. The design includes no laser or illumination functions — the body is intended solely as a battery housing — which also makes it useful as a counterweight or as a replacement shell on platforms that already carry the original device.

Key points

• The removable centre section accommodates batteries of different lengths without additional modification.
• The concave upper profile lowers the accessory on the rail, reducing vertical bulk compared to flat-body solutions.
• MIL-STD-1913 attachment provides direct compatibility with any standard Picatinny rail on a rifle or carbine.
• Internal compartment of 90 x 45 x 20 mm sized for two CR123A batteries, the most common format in tactical illumination and aiming devices.
• Faithful replica of the AN/PEQ-16 geometry, also useful in configurations that require visual consistency with reference equipment.
