"The gear box pin holes are out of alignment so the pin pulls the gearbox slightly to the right. The supplied mag release is weird and I'm glad I had a spare to install.

The spring for the charging handle was stretched, not a major problem to cut to length and bend the end to fit the screw but not expected on a new product.

The major problem I have is that the barrel nut thread is not the same as Real Steel, so none of the handguards I have will fit.

Not a bad body if you know what you are doing, but definitely not a good choice for your first build.

"This receiver isn't worth the effort it takes to fit gearboxes/barrel assemblies. I tried to fit two different version 2 gearboxes and both would not fit properly because the holes for the pins that hold the gearbox in place do not line up correctly. Because of this the gearbox sits at a slight angle near the front and blocks the magazines. I ended up taking a lower receiver from one of my friends for my gun build. The upper receiver needed a lot of work to fit the different lower and the barrel assembly. the lug for the main body pin needed to be shaved down so that it would work with the different lower, and the back of the upper needed to be shaved down to make it fit also. Even with the mods there is still a gap between the upper and lower near the back of the gun. There are also tabs that i assume are for locking the barrel in place inside the receiver that needed to be shaved down for it t fit my barrel assembly. Unless you want to do some work to fit the parts to this receiver and want a useless lower receiver, do not buy this.

"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.
