I paid about $900 for this one last year, during the height of the insanity. It is one that someone built as a good user. I'm an FAL noob myself, so I'm not a good source of information. I was told to go to FAL Files and read, read, read. I read until my ears bled, and I barely know more than it did when I started.
Basically what I know is this: There are some good receivers, and some bad receivers....from several different manufacturers. But you can't go wrong with an Imbel. It's cheaper to buy parts and mags for rifles built on a metric receiver, but inch pattern rifles generally have a few features that some consider to be improvements over metric rifles. I realize this has nothing to do with how much it will cost to build a rifle, but I felt like I should share anyway.
People sell complete rifles in the FAL Files marketplace all the time. Also parts and parts kits.
