What a shame! I just sold an L1A1.
My advise:
Look around on Gunbroker for a Century FAL. I have owned them for years and they work fine.
IMBEL MFG FAL 762X51 SEMI AUTO RIFLE : Semi Auto Rifles at GunBroker.com
Buy it now for $1189
Second:
Look at Entreprise Arms,
Imbel Parts Kit Refinished
$579 for a buildable kit
FN FAL Metric Receivers
$399 for a Receiver
OR:
FAL-SA58 Rifles-D S Arms
Rifles start at $1700.
