Fn upper review - FN America FN15 20 Inch Rifle Upper Assembly 36427

my cousin has this product, felt recoil is low and good, accuracy is excellent when using a variety of different bullet types and the upper does not get as hot as a carbine or mid-length gas system, so generally speaking accuracy is great, felt recoil is less compared to a 16 in barreled up and it runs cooler.
