I finally got my AC556, and I put it in a SCAR stock. However, when I was shooting it, it was only firing 2 shots at a time in both 3RB and full. The AC would shoot 2 rounds, and the bolt would close on an empty chamber without grabbing a new round out of the magazine. But, after I shot 2 mags, the gun ran like a sewing machine.

I let the gun cool down and I shot XM193 out if it. It ran without a hitch.

I don't know if it's the crappy ammo or the gas system is too or not dirty enough.

Thanks,

My AC556 functions much better with XM193.  When I use WWB it occasionally would short-cycle and the bolt would close on an empty chamber.  trgrhppy
