PTR 91 vs. CETME significant differences???

In terms of build quality, the PTR is a few floors up. The PTRs, however, are much closer to being brand new guns than the CETMEs. The PTR receivers are built on former FMP machinery licensed by HK. The CETME receivers are built by some privateers.
If you are just looking for something to shoot with, the CETMEs could be the way to go, provided you find one that works (as noted by others, some have not functioned well) and don't mind the unrefined build quality and upside down safety. The two CETMEs I have have worked fine. The PTR also the same.

The PTR-91 is a clone of the HK-91, which is in turn a semiauto version of the German G3 selective fire battle rifle.
The CETME is the forerunner of the G3. It was developed by German engineers working at CETME in Spain just after WWII, and is largely based on the StG45 design that never made it into production in Germany before the war ended. In the 1950s, the German Army needed new rifles to replace the M1 Garands its troops had been given after the war. It first tried to obtain a license from FN to let it make FAL pattern rifles in Germany. When the Belgians insulted the Germans, they instead went to Spain's CETME and licensed the rights to the CETME design. The Germans then made some modifications and improvements to it, which resulted in the G3 design, later produced for civilian markets by Heckler & Koch as the HK-91.
I can't tell you exactly what the difference are, as I'm not that much of an expert. I do know, for instance, that the sights are a little different. Some other parts are also not interchangeable, while others are. They look alike, though, and function in exactly the same way.

Rear sight: CETME sports a flip type while HK has a rotary elevation adjustment with windage adj. as well.
Front sight triple frame: CETME is elevation adjustable for zeroing while the HKs is a fixed blade.
Various cosmetic differences between the two: Stock and forend set is completely different( multiple HK variations)
Fire control box internals have slightly different components, bolt, carrier, trunnion all have minor differences.
You finding comparison photos of the internals would be easier than me typing them all out. RTG parts has a page on the interchangeability of the two.
Moreover, the CETMEs most of us know today were very crudly assembled by Century arms. They are made with a low quality reciever and well used parts kits. JLD builds new HK91 copies, on machinery they purchased from FMP in Portugal, which was an original contractor for HK. While not an HK, JLD is by far the best copy of a roller locked delayed blowback rifle on the market.
