checked these pout at taccom, i was surprised how solid they felt, when the guy said polymer upper and lower i kind of cringed but they felt great in hand, i don't know how they would hold up against aluminum ARs long term but that price is a great and its within most peoples reach so those guys on the fence about taking their first step into the AR world this is a great option and you get something with a free float handguard a little more modern look than many of the m4 style entry level rifles
