I am very excited to email you to say my AR45 runs awesome! I put 100 rounds downrange yesterday, just 2 minor hickups (with the SGW mag) but the OEM Glock mags ran amazingly well. Thank you Julia and please please express my gratitude to David as well. I really appreciate your level of customer service and the quality employees you have. I will be back soon (after the holidays of course).

I just wanted to take the time to show my appreciation to you all. First, I am a military Veteran and want to say thank you for honoring and acknowledging the service of this nation's Veterans. Second, I ordered an upper from you all yesterday and I am pleased that I am getting speedy updates about my order and the process that it is in. I have had a really bad experience for a month with ordering an upper from another company which I never received and ultimately requested a refund for. I was not able to reach anyone by phone to get an answer as to when my order was going to ship. I just wanted to let you all know that you have a customer for a long time in me because of your attention to detail and great customer service. I will be ordering more items from you all in the future!
