Here are the instructions on how to modify your BAR magazine to use 30-06 short blanks.
- J&M Spec. Short Blank Magazine Spacer
- M14 / M1A magazine follower
- M14 / M1A magazine spring
Step 1 – Remove the floorplate from your BAR magazine and extract the spring and follower.
Step 2 – Gently bend the three tabs on the bottom front of the magazine straight. This is best done with toothless pliers or a crescent wrench to avoid marring the tabs.
Step 3 – Install the spacer into the front of the magazine.
Step 4 – Modify M14 / M1A follower to fit freely in the remaining space of the mag well. It doesn’t require a lot of excess space. Just enough for it to slide freely top to bottom when kept perpendicular to the magazine.
Step 5 – Install the modified follower and the M14 / M1A spring.
Step 6 – Reinstall the floorplate and insure that the follower travels freely.
Step 7 – Carefully bend the tabs back flush. Magazine complete!
***If the magazine does not hold all twenty rounds then you can remove part of, but not all of, the lower vertical portion of the follower to increase the capacity.
