Great AR9 Glock Lower October 17, 2024 : David Scott from Gresham, SC United States   Lower was well designed and formed. Mag release system works great. Ejector fit well with upper and did not cause any drag or binding. I have worked several AR Glock lowers and can definitely recommend this one. Was this review helpful to you?

Exactly as described November 11, 2023 : from TN United States   The lower looks great, there was a small hiccup with no ejector and hardware in the box but after a quick email they had the missing pieces sent out immediately. I appreciate it, thank you! Was this review helpful to you?

Very Good Quality Item August 9, 2023 : David Hill from Flint, MI United States   These lowers are not as available as AR-15 Lowers.  When the item is located,  the price is usually very high.  MAS Defense delivered a quality part at a reasonable price.  Shipping was acceptable and the time to receive the item was better than average.  I will be shopping at MAS Defense for my builds in the future.  By the way,  there is no such thing as a 5 star ratting.  Perfection does not exist.  MAS Defense is as good as it gets right now.
