The US prejudice against the FN FAL (including the inch pattern L1A1 SLR) is that they'll inevitably choke. However, Bloke's legit BSA L1A1 ran like a champ at Finnish Brutality 2023, with only one very minor hiccup at loading on the last rifle stage. Interestingly, the same hiccup that Ian's (Forgotten Weapons) G3 had several times, starting much earlier.
