By the way,
Start proofing your system with one round fed from the magazine, and ensure that the magazine follower locks the bolt back. Also take note of what direction your spent brass flies, and how far. Look at the fired case before proceeding, checking for any pressure signs...cratered/flattened/pierced primers, eschar on the brass, split case necks, swollen bases, and ejector recess brass flow (where the molten brass has filled into the ejector channel against the force and mass of the ejector and ejector spring).
Do NOT use that SMG buffer in a gas-operated system.
