    "This is a good lower, and I recommend it.
    It's fairly bland, but the build material is great and it's well suited for laser engraving."

    This does not fit King Arms uppers at all, but it will fit JG uppers (It fit mine without a problem)

    "I purchased a Bone Yard Matrix M4 Zombie a while back that had a broken tail on the lower receiver and was worried that finding a lower that would fit would be a problem.
    Picked up this JG lower and it fit the upper receiver perfectly.

    Lower Receiver:
    -Not too light, not too heavy, comes in at about 7oz (200g).
    -Casting is good.
    -The body pins going through the V2 gear box all lined up.
    -Mag well is a bit big in that an inserted mag is a bit wobbly... but then again I haven't
    found a mag well yet that is perfect..., stuck on a piece of Velcro inside and the mag's
    now secure, but not too tight.
    -No markings on the receiver is nice also... I like'em blank.
    -Receiver doesn't have a flat area on the tail to allow rear wiring between the buffer
    tube so you will need to drill a small hole at the base of the tail to pass the wires
    through the tail to stock. No big deal, I've had to do this on other lower receivers.
    -My V2 gear box didn't fit at first and I had to file the trigger hole just a bit.
    Again no big deal, a little flat back spray paint and you can't even see the slight mod.

    The only real con is that it doesn't come with a firing safety selector lever switch...,
    which means you will have an exposed hole on the opposite side of the receiver.
    This hole is usually plugged by the manufacture using a pressed in plug.
    (haven't been able too find this plug on anyone's site)
    I stuck a piece of electrical tape on the inside to cover the hole and keep out dirt.

    If you are looking to upgrade your plastic receiver or just a replacement, for the price, this is a goo deal.

    "Build quality is good, as I have come to expect from JG parts. The only problem I had was that I also ordered the JG flat top metal upper receiver thinking that they would fit together, and they didn't. Tried modding to get them to fit, and the lower seems to be appx. 1% undersized from the upper. Just couldn't do it.

    If you plan to get this with the JG upper, as soon as you get it, check the fitment before any modding. If it doesn't fit, contact evike.
