Finally got all the bugs worked out. It's a custom built FAL. Dan Coonan receiver with Imbel parts kit. I got it and slicked everything up a bit, installed a new action spring set and scope mount. I'm VERY pleased with the accuracy, much better than I expected. I've been shooting my own handloaded 308's through it - 175 grain Sierra hollow point boat tails with IMR 4895. Lots of fun!
