Anyone has experiences on these FN button cut barrels?

Yes and I would choose FN over pretty much any other barrel manufacturer. That said I’ve never had good luck with primary arms — a few barrels were not as advertised. Big hassle to get a timely refund for their errors.

Yes, they’re amazing! The quality is apparent and they shoot great too...
