The FAL is a fine rifle and easy to maintain in the field. The sights on the FAL suck. I never understood why they did not put the same sights on it as the Garand or the M14. However it is still a fine rifle and can give great grief to bad guys down range. At 100 yards using rapid fire I can put most of the rounds in a pie plate using an FAL.
I had a HK-91 civilian G3, and never really liked it all that much. Hard to clean with the blowback design, and it did have a nasty recoil impulse. Possibly due to the delayed roller lock blowback action. Tore up brass but was very accurate with iron sights. Always liked the looks of the FAL, too bad I never got to handle one.
