A&K 249/MK46 Box Mag Insert No Modification

Enhance reliability and capacity by replacing your factory box magazine insert with this innovative design. The system features a robust clutch that remains intact even when debris or faulty BBs enter the box. It is designed to self-regulate the feed rate, capable of feeding up to 40 rounds per second with an 11.1 battery.

All parts are made with high temp materials, so if you accidentally leave a box in the car in the heat of summer it will still operate properly.

Installing this product will require soldering. Please contact a local tech if you aren't comfortable doing this yourself.

Due to the variation in how machine guns are wired up, this has been left up to the end user. If being used with a hpa engine, a relay will be required to run the box off an 11.1v because a 7.4v battery does not make enough torque to fully engage the clutch.
