I agree with Death_By_AR, I have a beautiful FAL/STG built by Arizonia Response Systems (ARS) and love it. It is not as accurate as my SA M1A, but it is as accurate as the AR-10A2 with the factory match trigger and 4x12x44 Nikon Monarch scope I had. The FAL had an 8lb military trigger and iron sights and would shoot 2-3 inch groups with any surplus I could shove in it, so would the tricked out AR-10. The AR-10 would tighten up with with factory foddor, ditto for the FAL. The FAL mags are $7-$10, the AR-10's were $75-$100. I don't know if the FAL can jam, the AR-10 was a Jam-O-Matic (with those ExPenSive Factory converted mags). Now the AR-10 may have had a potiental for superior accuracy, but the potiential for problems was undoubtable. My FAL IS unstopable, 2-3 inches with surplus and 1.5-2 with factory.
Good Luck
