Some magwells may be tighter than others. Installation can be made easier if you push the CompMag in against the locking wheel to keep the back end of the mag flat against the back of the magwell. This keeps the CompMag from tilting in the magwell and helps it go in straight.
For receivers with Cerakoted magwells we recommend roughing up or removing the Cerakote inside the magwell where the locking wheel sits when the CompMag is inserted. You can easily do this with a bit of sandpaper. Cerakote is a slick, hard surface and will prevent the locking wheel from engaging so it must be removed for the mag to lock in properly.
NOT compatible with lowers that have a custom or extended magazine well. It will work with the Ruger 5610 even though the magwell is not a standard shape.
