Inspection
A visual inspection is recommended each and every time you clean a magazine, the
magazine is disassembled, or a problem exists that could be magazine related. The
following are guidelines that can help in identifying and solving magazine related
problems.
Many problems are very often related to incorrect operator use or maintenance, faulty
ammunition and/or problems in the weapon. These areas should be checked for problems
at the same time the magazine is inspected. If the same problem exists with more than
one magazine, then more than likely it is a rifle, operator, or ammunition problem. When
problems do occur, mark/identify the suspect magazine with a tag or paint/grease pen and
use the following as a guideline. Check for proper assembly. Inspect overall function of
follower (free movement), locking tabs, dents, cracks, etc.
1. Housing: Inspect feed lips for dents and proper spacing, sides for dents, magazine
catch area for worn surfaces or dents, cracks, etc.
2. Follower: Inspect for free movement inside of housing, dents, cracks and deformities.
3. Spring: Inspect for bends, cracks, weak tension.
4. Locking Plate: Inspect for worn or broken tabs. It should retain floor plate and stay
securely attached to the spring.
5. Floor plate: Inspect for bends, cracks and correct fit of the locking tabs into the
locking recess of housing.
6. Rubber bumper: Insure bumper retains floor plate into housing when assembled and
there are no signs of extreme wear.
If any problems are identified, repair or replace as necessary.
