I've bought several of these for multiple AR builds . Very easy to complete and they hold up fantastic. I've put several thousand rounds thru each rifle and thesee lowers show no signs of wear. I'm running a .223, .300 BO, 6.8 spc, and a 7.62x39. No complaints. I'm looking to build one more in 450 Bushmaster and I see no problems with using the EP lower. I've got a couple aluminum lowers as well and I prefer these over them any day of the week.
