My CETME built over 10 years ago will only take G3 Mags. Cetme mags seem to bee too tall and don't allow the bolt to close.

The magazine well on the original CETME was designed for a curved magazine. The G3 magazine is straight. Some of the lowers that Century used were designed to match the original CETME mag well - like the one that I owned. Others were closer to the G3 shape. So never assume that a CETME build.
