*** Local Pick Up is available by appointment only in Charlotte, NC. 



*** Shipping timeframes have been delayed due to the increasing demand for AR15 parts. Parts will ship in approximately 2 business days. Barreled Uppers are built to order and will ship in approximately 4 business days.  *** Orders can NOT be edited, changed or modified in any way once they have been placed. Please make sure your are 100% sure you are ordering the correct parts. Give us a call before you place an order if you have any questions or if you are unsure of fitment.

 

MAS Defense is making some changes! We are upgrading our website to be more 
user friendly for customers and dealers. Changes will take place in June 2016. Please
note, MASDefense.com will stay the same. If you have Shop.MASDefense.com
