true that. when i was getting a LGS to transfer a lower for me, they were saying that they could sell me one cheaper than i could build it. i asked what they had, and they had a $700 rifle with a pencil barrel and m4 furniture, as well as other deficiencies, that was well over $100 more than i was building a 14.5, gov profile ar15 with all milspec parts and magpul furniture lol
PSA lowers are gtg. All the the above brands are manufactured by the same company. There are only a handful who machine their own, like Aero Precision for example.
