Its a little fugly but it's got where it counts.
The CETME is the Pappa of the HK G3. When HK was turned down by FN to produce the FAL, they took the CETME as a patern to develope there own rifle. The two look similar on the out side but the HK has they roller system that makes it a sweet rifle. Rollers are not required for a good .308 auto rifle as there are several others that are fantastic without them... the FAL, M14, etc... and the CETME. It's an older design, but they function very well.
Accuracy? About average but not as tight as a G3.
Since its an odd duck - not many around and many smiths don't work on them regularly - I'ld take the FAL clone. Cheap mags, cheap parts, easy to find... I saw an L1A1 NIB for only 400... it was rough as hell but take the money you saved and put that into some good smithing
