H&K MP5 K-PDW BB Magazine

Engineered a Speed-loader for this Magazine & Gun, 3D Printed, can load a full mag in about 10-20 seconds. https://www.thingiverse.com/thing:4631900 Free to use / Tinker, just send me a new design if you do tinker.

Pros
Great to have 40 rounds of BBs in a stick, not too bad to load, just time consuming.

Cons
A small opening to load the BBs makes it tedious.

Can be speed loaded with a straw if you put your mind to it

Pros
Works

Cons
None

This high capacity bb mag holds 40 bbs per mag and will eliminate the hassle of traditional drop-free mags which can be emptied immediately leaving you stuck loading instead of shooting

Pros
High capacity mag holds 40 rounds

Cons
Takes a while to load each round in due to manual feeding
