A quick look at the BO Manufacture Diamondback DB15 7" Honey Badger AEG in this video by Airsoft Master... "The Bo Manufacture has done very well with making the Fully Licensed Diamondback Honey Badger PDW AEG rifle. I do like this rifle having an integrated rail system and that it comes with a ETU from Poseidon.   Wait, it even comes with a 6.03 tight-bore and a mapleleaf macron bucking?! It seems the standards for aeg rifles has changed. Check out these rifles and buy one at airsoftmaster.com!"
