Ordered two DTT AR15 complete build kits and put on PSA stripped lowers for my sons, I built them, did not have DTT assemble them. DTT offers more free float handguards options in kits than PSA and at better prices. Shipping was in about 2 weeks, when you get delivery tracking change shipping to a FedEx location (walgreens for me LOL) if you have to sign for orders. Everything was included as promised, rifles shot well and were accurate. Ran 250+ rounds through both without any issues at all using good ammo and magpul magazines. Seeing all these poor reviews, not my experience. Takes them a day to reply to emails or chat if you have questions, pretty standard. My guess is some people order AR parts and kits online and have no patience, I get it but even Amazon takes a couple weeks or so and they are a trillion dollar company. Dont be scared by the poor reviews.
