    There is no way that ANY OF YOUR GUNS will be able to shoot properly.

    Why do you say that? I have made dozens of them and to me they sure seem to shoot "properly".

    Well, nothing personal but the 'semi auto' mech of yours jams alot.
    Elastics may pass the bullet.

    Well, this is an old model (about 3 years old) which had its faults which I have done my best to fix. I have not noticed any jams in my last couple semi automatics, and as for the the elastic passing the bullet, the rod behind the ammo feed feeds the rubberband at a height at which it will catch on to the bullet.

    I was making this, and I was wondering if it is correct that the rubber band flies off each time I shoot.

    It's OK. However if you don't want then to fly off I'm sure you'll manage to modify it so they stay connected to the gun. Also you may want to know that this I'ble is outdated for the MAR-3 was posted already.

    Guns like this are pseudo semi auto.  The mech has been done before.

    It is actual semi-auto so you just have to pull the trigger to shoot.
