WELCOME TO OUR STORE!

MAS Defense is committed to providing "Quality Parts at Reasonable Prices!" Our foundation is built on excellent customer service, honesty and integrity. These simple guidelines are what has made MAS Defense the preferred company it is today.

We have spent countless hours developing a updated, user friendly site for our customers. We welcome all feedback on how you think the new site is working or suggestions you may have on improvements that could be made. Please note, customer accounts were NOT transferred. Everyone will have the option to create a new account or to check out as a guest. We definitely recommend registering so you can check on orders, stay up to date with our newly added items and be notified first of all flash sales.
Thank you for your business and support!
