Another ingenious upgrade part from HS-Armory these magazine followers are designed to improve feeding and reduce jams. In most mid-cap magazines the follower (the device the spring is attached to that pushes the BBs through the mag) is rather crudely shaped and often allows the BBs to be staggered in such a way where much of the spring force is transferred into pushing the BBs against the mag walls instead pushing them out. This pressure greatly increases friction which causes the BBs to feed slowly and often jam. The REMF is designed to align the BBs perfectly so the two interlocked stacks are pushed together instead of one trying to push the other. These REMFs are a further improvement on the original UEMF in that they trade universality with increased performance. They are designed to be much more flexible and be a closer fit with magazine slides which means faster feeding and less jams. Unlike the UEMF though they are only confirmed to fit certain mags (see list below) although they may fit others that have just not been tested yet. They should fit M4 (users have also had good success in AK mags and even P90 mags with slight modification) mags that have large radius turns and square channels.
These followers have been tested with the following mags:
MAG plastic mags
King Arms VN mags
They are reported to generlly not be compatible with MP5 mags at least without modification due to their tighter turn radius.
Also have had reports that some slight sanding may be needed on King Arms M4 mags.
