I bought this upper along with everything but the stripped lower. Runs great with CMMG LPK, M16 BCG and H2 heavy buffer. Nice soft shooting pistol for a great deal!I liked MAS Defense product and service so well, I ordered a custom 9mm upper with a 7.25" barrel and the same handguard on their slick side upper.

More than just putting parts together. Master craftsmanship and attention to detail. Runs like a clock. First time buyer and yes Mas Defense will be my go to company!
