Hello! TL;DR - WE TECH 416 with upgrades (extended Prometheus barrel, ra tech bolt and carrier, more) - hella mags - cheap price, add more mags, price goes up. we tech hk 416 GBBR! It's got ra tech upgrades, I know ZIP about GBBRs but! This one has an extended barrel, I believe prommy, shoots like a BEAST! And it's got a stippled and amazing pistol grip. It's a very hardcore build quality (feels almost like steel!) , comes with 2 regular we m4 black and one brown mag, 1 Vietnam style short mag, and a few disassembled mags and I'm a noob, dunno how. The assembled mags have been tested as working perfectly, I just dunno how to assemble and test the others. So I'm tossing them in FREE IF ABSOLUTELY NEEDED I HAVE 8 total (7 more) WE M4 MAGS BUT! I want to keep those for my EMG KA PDW M2 Stock options: MOE, trident (krytac), FDE crane
