The Tasco SS is a great scope (especially for the money). I have one on a bolt gun, and I'll probably pick up another.
However, the FOV is WAY too small to pick up targets quickly. Fixed 10X is fine for a fixed-position, you-have-all-the-time-in-the-world gun, but it's a bad choice on a "tactical" gun like a FAL.
I'm putting a Leupold 3.5x10 on my AR10, and it will be set at 3.5 unless I happen to be in a fixed position and need to engage long distance, where there's no big time factor. Trying to find a target 50 or 75 yards away with a 10X scope is going to slow you WAY down. People who get a chance to shoot 3-gun or IDPA-type matches learn this very quickly. Most experienced hunters also use variables, and keep them cranked down to low power while they're stalking. Only rarely is the high magnification useful.
Actually, I'd take a fixed 3X scope over a fixed 10X scope for a FAL any day. But a quality variable is actually VERY useful on a FAL, AR10, M1A, etc.
