5 of 5 300 BLK Upper April 7, 2022
: Paul Woltmann from United States  
MAS Defense went above and beyond for me. Was looking for an item that was out of stock and messaged customer service. They got back to me immediately! The product was out of stock but they set me up with a *blem which I could not find even the slightest blemish on. Upper functions great, looks great, and with customer service that good; you can't beat em! If your debating ordering from MAS, just do it you won't be disappointed.
