- For use in USGI type 30 round magazines for the AR15/M16. 
- Will also fit SCAR 16 GI Magazines. Not factory FN SCAR 16 magazines.

-Original military style green USGI followers may need to be trimmed or replaced to work properly. If your followers have a green spike in the middle this will have to be cut down to work properly. Please see the training video section or the other photo here for instructions on how to do this. The link to the FAQ section also provides more information. 

-These will not work in the Surefeed E2 USGI AR-15 magazines without modification.
