5 of 5 Great product, even better customer service October 21, 2021
: J W from Sterling, AK United States  
The fit and finish is good. Everything arrived neatly packed and in good time. I was contacted by MAS defense prior to shipping to confirm everything was correct with my order which I appreciated. I will certainly be doing business with MAS defense again.
