This is my second purchase and just like the first one everything was great! Great products at really good prices. Super fast handling and shipping. Who doesn’t love that! Shoots extremely well. Fit and finish is outstanding! Highly recommend MAS defense!

This upper is way better then I thought it would be.  Very well built, looks great and an unbelievable price.  I will definitely buy more parts in the future.
