Description
PEQ-15 Battery Box (OD)
This is a PEQ-15 style battery box in od. It replicates the shape of the AN/PEQ-15 aiming unit seen on many modern military rifles. In airsoft, units like this are mainly used as a rail-mounted housing for a small AEG battery, which is especially useful on rifles with little room in the stock or handguard.
A PEQ-style box is one of the most popular accessories for M4 and similar rifles because it looks right for modern military and special forces impressions. This version is listed as a battery box only, without a laser, so it is a simple way to add the look and gain battery space. The od finish suits olive drab furniture and woodland loadouts.
Battery storage
The box opens to give access to a hollow interior where a small battery can be stored, with the leads routed back to the replica. Battery sizes vary a lot, so check the internal space against your battery before relying on it, and route the wires so they cannot be pinched or snagged. The exact internal dimensions are not stated in the listing.
Look and setup
Mounted on the top rail of the handguard, a PEQ-style box sits naturally in front of the optic, as it would on a real rifle. It can also go on a side rail if that suits your setup better. Keep it clear of your optic’s field of view and any front sight.
Fitting
Remove the magazine and battery from the replica, then position the box on the rail and tighten its mount. Check that the battery leads reach your connector without being stretched and that they do not interfere with the handguard or optic.

Brush off dirt after games and check the mount is tight. Remove your AEG battery from the box between games and store it safely, and check the wiring for wear where it leaves the box.
