    7.62x39 Upper finally done!

    I will post pictures as soon as I can. I took it out to the range this morning, and tested it out. It had some teething problems with the plastic magazine ( by MWG out of Florida), but those seem to have cleared up as I shot it more. So here is the basic rundown on what it has:

    Kaiser Defense lower
    JD Machine upper
    JD Machine Rail height railed gas block (I guess that is what you would call it.)
    AR Perfomance 7.62x39 barrel
    AR Performace BCG
    MI Rail height front and rear folding FDE sights.
    YHM Muzzlebrake/ flashider combo
    YHM Diamond mid-length rail
    Magpul FDE pistol grip and collapsing stock
    Tapco FDE front vertical grip
    Eo Tech 552 Holo sight
    Assorted brands of rail and ladder guards, all FDE

    The HK/AK style folding front sight works especially well with the holo sight. The sight seems to fit the holographic ring perfectly, making consistant sight pictures a breeze. The recoil is less than a 6.8 of a similar weight. I was using Winchester ammo, as it was an indoor range, and Wolf/ Surplus ammo was a no-no. It was printing about 1 1/2" groups at 25 yards, which was much better than it sounds, as the target was under a fan, and constantly rocking back and forth. Aside from the 2nd to the last round constantly mis-feeding, there were no problems with it's performance. As I said before, I'll try to post pictures of it as soon as I can.

            Sorry, this is the best I can do right now. I'll try to get higher resolution pictures up some time soon.

                Yes, that is my glowing, white foot. This is as large as it will let me make it in an attachment.

                    Try a hosting website like Photobucket or Imageshack.

                            I enjoy my 7.62 AR. I've only shot it a few times, but it is fun. Can't wait to get out some more with it.

                              Thanks rct. I am totally incompetant when it comes to posting pictures. For those who want to build one, I really recommend the bolts from AR Performance. They are much heavier duty than most of the other bolts out there, which is important with 7.62x39 ARs (which are known for breaking bolts). The also have the added bonus of being able to use standard .223/5.56 extractors if you need to. The come with a heavier duty one made for 7.62x39, but will work just fine with a .223 version. The barrel was actually the hardest part to find. It took me almost 6 months to find one that didn't cost an arm and a leg, and was in stock. JD Machine is working on tracking down a quality barrel maker to do some, but I am way too impatient. I ended up getting one from AR Performance, simply because they had them in stock.
