Magazine Catch is serviceable but has issues

Most of the parts are perfectly fine with no quirks, but the magazine catch is not quite right, the way it is cast lets numerous brands of magazine be pulled out of the magwell when they should be locked in, (namely Mission First, C Products, and various oddball GI mags though other GI mags work just fine). This was not a fluke with 1 kit as I have used 2 of these and they both had this issue. I replaced the catches with different ones and the problem was immediately fixed in both guns. Also, Magpul magazines will not seat while loaded with this kit's magazine catch.
