The Next Generation of High Performance Competition Ready Magazines for BUL Styles.

Made from Heat Treated 410 Stainless for Ultimate Durability.


No spacer required for 9mm/.38 magazines.


We built a specific competition ready mag to ensure that it sits at the correct height within the new frame from Bul Armory. This puts the bullet in the optimal position to provide smooth, seamless feeding and reliability.

MBX Complete Magazines were designed to be Competition Ready with exclusive features to meet the highest demands for today’s Shooters.
