"Overall, a good body at a great price. Some work may be required. Came in JG packaging. Comes with receiver pins, gearbox pin, charging handle, and bolt hold open mechanism. Needs a one piece hop-up unit, the fake right side selector switch cover, and fake bolt plate.

I bought this body to install onto a new JG M16 with a two piece barrel and a plastic body. Here are some issues I ran into:

1) The upper has two protrusions inside the hole the barrel slides into that are supposed to interface with the hop-up channels on the barrel/trunnion. These protrusions,or tabs, ensure that the hop up unit, barrel, and receiver are in alignment. In my case I had to be cut and file the hop-up channels on my barrel trunnion to accept the tabs.

2) The barrel nut from my two piece barrel would not thread onto this body. Having taken a caliper to each, it appears that the threads on the barrel nut are too small, but they could also be threaded differently for all I know. I ended up using a one piece barrel and the barrel nut that came with it (which also solved problem #1).

3) The body's stock extension was too large in some areas to accept the rear sling mount/buffer tube spacer plate without filing.

4) The paint inside all of pin holes had to be removed in order to punch all the pins in.

"I received this metal body for christmas and at first I thought it was broken because the holes on the receivers for the front locking pin are not aligned and the dust cover did not open when I pulled on the charging handle. At first I had to use a hammer to get the pin in and out but working the pin in and out fixed the problem to the point where I can push it in with my thumb and pop it out with an allen wrench. The dust cover problem was fixed entirely by putting in a dummy bolt from my original body.

fits my Madbull Dragon Fire rail system
came with the charging handle, forward assist knob, and selector switch already installed
upper receiver slides off lower receiver instead of pivoting off
easy to install
comes with its own hop-up

made by Dboys (this company makes lesser quality airsoft guns)
you have to assemble the hop-up
the mag catch it comes with is confusing (use your own)

the pros out weigh the cons in my opinion.

"the first thing i realized when i got this was that it was a dboys brand body. at first i though it wasn't going to be good, but once when i opened it up i was amazed of the amount of detail they put in to it. every thing came together perfectly, except that the dust cover latch's screw came undone, and that the charging handle didn't even pull back as much as the others, but other than that it was awesome. i give 4 stars because of the latch and the handle.
