Brief M249 boxmag 'how to' guide

Just thought i'd show you a brief 'how to' guide for a boxmag for your M249/Minimi/LMG mod's etc.This particular one uses a Reloader B's internals.Dimensions will be different to mine depending on capacity etc but the width will be around 91mm

1st job is to cut the feed down and 'weld' it together with a soldering iron and then used epoxy resin to strengthen it(don't ask about the colour!)





I've knocked up a plastic sleeve that slides over the feed neck of the hopper,it has an internal o ring in it to stop it slipping off.The other end is machined out to accept Q-loader/dishwasher hose etc


I've made an internal feed tray so the balls feed the hopper



Here it is shown how it'll look with the hopper internals



I've decided to bolt the feed unit to the feed tray and the feed tray to the sides so i can take the bottom off without unbolting the feed unit.It'll make battery changes far easier.The Q-loader feed tube isn't the right length,it's just there to give an idea of how it'll look when complete



The board is mounted on 2 stand offs and bolted to the side panel,2 holes were drilled,one for the on/off button,the other for the LED.



Added a ramp to alleviate some weight/pressure off the feedunit so as not to get any feed issues/jams

This is what it looks like when fitted.

This one was fitted my Ion M249


Here's one i did that went on an A5 M249



Any questions,just ask

About the same weight as a fully loaded Pulse.But it all depends on what material you use to build it with.

Very cool, I love projects like this!

Though I have to ask, could you have used a warp feed?

Warp is to tall plus you need an agitating hopper(probably)to feed the warp
