    Very cool and good start.

    (I really like your combination carry handle/top cover pivot pin. Very clever) Just kidding.

    Yea, that's pretty cutting edge stuff. You can add it into the original design if you want, but I demand it be named the "Mustang Handle"

    Do you think that dropping the feed tray back 12mm from your original position is right? My main concern is that the feeding angle would be too sharp in the original position.

    I would recommend that the nose of the bullet just enters the chamber when the base of the cartridge case leaves the belt link. The longer 7.62x51 case should put the base farther back than with the 7.63x39 so the feeding angle will be less anyway. Cntrailrider has had success with his feed tray farther back than mine though but you have to have the bolt traveling forward fast enough to throw the round into the chamber if it is mid air when it leaves the belt link and before it enters the chamber.

    Mustang -

    Lookin' real good. Not a good idea to have cartridges flying through the air (unsupported). Almost nosing in the chamber as it's leaving the link is best, and the path always seems rather steep. Height of your feed tray is critical, to overcome the steep angle.

    Real nice pictures - keep us posted

    Got the ejection port (super-sized) cut, and the trunion mounted. Now comes the hard stuff...

    GOt the lower rails made, the bolt is sliding as well as the barrel back on today. I sure do love this "screw build" and being able to take it apart and put it back together over and over. I may never smush a rivet again.

    Sorry, no pic today....

    Looks great. From your last picture it looks like you are going to need to open up the ejection port on the left sideplate some more to get the brass to clear it.

    Yep, I'm gonna wait until I get it sliding to know how much to open it up.
