: Greg Ilko from Beech Grove, IN United States  
Solid company who treats their customers with courtesy and respect.  Quick turn around on order and trouble-free shipping.

And the product is high quality.  Extremely satisfied . . . again.  This is my 2nd MAS upper and no problems with either.

: Jonathan Howard from Easley, SC United States  
This is my second upper from
Masdefense.   No complaints with quality and the price is great.   I encourage anyone who is hesitant to try them out.  Quality parts at a great price.

2 of 5 Shipping was bad December 9, 2018
: Elvin Perez from Mahanoy City, PA United States  
I paid over $30 for 3 day shipping, and it took a week for me to get my parts, the parts and prices were great though

Reply from MAS Defense:

Elvin, I apologize for the inconvenience. Your order was placed on 11/26/2018 at 10:08PM. We shipped your order on 11/30/2018. Lead times are the amount of time it takes to process your order and get it to shipping. We were at 3-4 business days at that time for uppers. We are looking into ways to reduce the lead times during the holiday season.

Thank you for your feedback. We appreciate your input!
