ACR 5.56 EGLM can be loaded with 20Rnd and 60Rnd mags, but EGLM's magwell is higher than 20rnd mag, but too thin for 60rnd mag. .
For SCARs we removed both 20rnd and 60rnd mags because of this, guess same should be applied here.
Expected: 20rnd and 60rnd mags are not available for ACR 5.56 EGLM versions.
Or 20/60rnd mags should be available both for ACRs and SCARs
