I built an STG58 parts kit on DSA receiver,with some DSA parts.IMO,DSA is as good as can be had.
The FAL is a fine rifle,IMO.Tough and reliable,easy to maintain.Iron sights and my poor marksmanship,mine grouped about 3/4 wide by 1 1/2 tall groups @100yds,iron sights.As the bbl warmed up,it would walk some.I could not work much improvement on the trigger.It was quite useable,not horrid,a battle trigger.IMO,you chose well.Have fun!
