Dirt:
A "real" FAL/L1A1 based on an Imbel or DSA receiver is around $1400 or more but if you educate yourself you can get a CAI for around $700 that functions just as well as the high end versions. I finessed myself one from here. (MGO), that cost me, for the weapon itself, about $400. Since I was educated about the issues I determined the problem and now have a perfect L1A1/FAL that I would trust my life to.
I say that as someone who carried the SLR, (which is the L1A1/FAL), for ten years and trusted my life to it... Now I have one that dear old Elizabeth doesn't have to lend me to go and do my business...
