I have owned both and yes some parts will interchange. but the CETME is not as finished looking since the receiver is not made by HK. About same moa rifle and mags and trigger pac and bolt assm do interchange. Sold the cetme and bought a 91a3,been looking for a 93 but those are hard to find in vg condition.Sold the 93 15 years ago ended up buying a 43, but sold it a year later.Stan
