My $0.02 is that I bought a G3 clone instead of the CETME in January. Rationale?
1) I don't like the ground bolt that is showing up in CETMEs sporadically. I have an engineering background and personally don't believe that operationally it is dangerous, however it does give a false reading on wear in the trunnion, bolt, roller lockup. What I read into this is that the "parts bins" have mostly worn out used parts and they are being fixed with a field expedient method. The G3 clones aren't showing up this way.
2) Sorry, I like the G3 rear sight BETTER than the paddle on the CETME. Better sight picture and windage adjustment method in my opinion (YMMV)
3) Sorry, I like the G3 stocks better than the CETME wood...especially the green ones. (YMMV)
4) Overall, used part availability is better (do a search on eBay) and new parts are available in a pinch.
For me, it was worth an extra $100 to get these advantages. I am not comparing either to FALs, M1As, etc as each has its own advantages and bit of history. Nor am I comparing it to the HK91..come on, $2200????? Outrageous.
