If you've ever wondered how people manage to store batteries in their weapon when they don't have a buffer tube, and a tiny hand guard, well here's your answer: they're stored and hidden in a mock PEQ box which is hollowed out inside to store battery!

Full description


A mock PEQ Battery box might sound a bit boring at first, but when you need one it'll be the best thing you've ever purchased! These types of mock battery box are designed to be attached to weapons where there is not enough space to hold batteries, not enough space to hold a large style battery, or even for those with fiddly hand guards where it would be easier just use the PEQ box than trying to gain access to the existing battery storage. When used in conjunction with a front wired gearbox these bits of kit allow you to use even the largest 11.1v or 9.6v battery on a rifle which may not have been designed to accommodate them. Some people even buy them just to simply hold two battery at once so they can quickly switch power-source in the middle of a game.

This PEQ box is perfect for those who are building a project gun which has a skeleton stock and small handguard leaving no room for battery storage, or for those who have a fiddly battery compartment and want to make it easier for themselves to replace the battery in their gun.


  • Designed as discrete battery storage, made to look like a PEQ Box
  • Highly detailed to make it as realistic as possible
  • Large cable routing hole to the rear of the box
  • Designed to store large battery
  • Easy to access, the back simply comes off
  • Attaches to 20mm RIS / RAS Rails
  • Tool-less attachment
  • Easily fits 9.6v NiMh or smaller batteries
