Answering the OP's question, I think almost any rifle with a pistol grip is better, ergonomically at least, than the M1-M14 pattern stock.
I have a M-305 that 45ACPKING worked over, and it's a really good rifle. Accurate and reliable.
Having used the FN C1A1 when I was in the Forces (way back in the day

), I thought it was a great rifle as well.
If money were no object and we didn't have to deal with our idiotic firearms laws, I'd want to get my hands on the Brazilian version of the FN-FAL, the IMBEL. IIRC FN stopped manufacturing the FAL in 1975 (If I'm wrong, please tell me) but again IIRC IMBEL still makes the FAL pattern rifle (of course, I could get one from DSA in the States - assuming again we didn't have our dumb laws)>
