i was a little scared to buy this for my mauri simply because its echo 1 and im not sure i completely trust their products yet. im not sure why the price is so dramatically different from the other box mag but this one shoots flawlessly. i really do believe that it probably has to do mostly with wut kind of m16/m4 mag you use. i use a g&g 450rd hi cap mag. i was blown away with its performance and am quite happy with my purchase.
performs as well as the more expensive model.
holds all the ammo you will need for quite a few rounds.
looks godly on your gun.
gets rid of those awful p90 mags.
nearly 100 dollars cheaper than the other model.
it says echo 1 on the product and i am not a fan of echo 1.
also, did not come with the wiring, battery sleeve, or security strap.
