18" rifle length barrel by trybe - TRYBE Defense 18 in Medium Profile AR-15 Rifle Barrel, .223 Wylde

i ordered one of these barrels which i installed in a upper everything fit fine , has strong 5r profile. slick finish and seemed to be correct in the chamber. now the gas port looks a bit large --however a rifle uses a pretty big port and the reduction in dwell adds a tiny bit more to the ports size so i think it will be OK the second barrel is identical to the first-- now i haven't fired either of um as of yet--but they certainly looking good so far--
