Product was perfect and received it very quick and the prices are actually very reasonable for the quality of product. One stop shopping, they have everything I needed, the folks I spoke with on the phone were friendly, knowledgeable and a complete pleasure to speak with, looking forward to my next project and future purchases from MAs Defense

This is my 2nd upper from this company and it works great so far. No issues and it shoots really well.

I have ordered twice from Mas Defense and I must say that their products and service is top notch. Orders are always shipped lightning fast and securely packaged. Mas Defense is my new go to supplier for any new build.

I have purchased several upper assemblies from you in the past and I am always impressed with the quality and the price. You can not beat either with MASDefense.
Timely and economical
