According to what the paper says, all models feature a H&K profile barrel, no matter if green, black or wood furniture.
Furniture can be replaced afterwards, if it is real Mil-Spec.
If people want an authentic clone, then they don't go wood furniture and polymer grip.
And by the way: green furniture and Navy trigger group/polymer grip was the standard (infantry) configuration which has been in service in Germany until the G3 got replaced by the G36.
Everyone wants a G3, but who is willing to pay for it. That is why most people settle with affordable clones.
Interesting would be what parts the PTRs are build of, and from where the parts come?
That's just for the classic and GI models, all other models use match BBLs with shallow flutes...
The PTR initially used all licensed parts from H&K, Rheinmetall, EBO/Hellenic, and FMP....
The newer PTRs are built completely in house, and I have compared the new PTR made parts to H&K, RM, and EBO parts I have. The PTR is most definitely high quality, and aesthetically superior to even H&K... but they did have a couple issues with improper heat treating when making the transition a couple years ago...however fixed now. My PTR91 SC is newer and made from PTR parts, unlike my other two PTRs using surplus parts... I've shot only about 1,200 rounds through it, but no issues.
To be honest, the welding and fit and finish of the newer full-inhouse PTR exceeds H&K quality. I know that hurts some egos, but I can assure you it's not even debatable... Reliability and whatnot I guess are yet to be seen, but since the "GI" and "Classic" are using proper chamber specs, off H&K tooling, with quality parts, I feel fairly confident they would be as reliable as the real deal. Having subjected the basic "target" PTR to some real abuse, I know the PTR, and the design in general, can withstand some real torture and elements......it should be noted that PTR used out of mil-spec chambers purposely in some attempt for accuracy, recoil reduction, or brass salvaging, I'm not sure why exactly, but I think they never should have messed with depth specs. That said, I have three PTRs, two of which have the match grade barrels with shallow flute depth, and both are extremely reliable, as long as you note to not use tar sealed and generally questionable ammunition..
I am an unapologetic PTR fanboy, but before that I was also an H&K fanboy. I am still a proud owner of H&K firearms...but the fact is the PTR is "just as good or better" than the original, and should really be classified in the same tier of original licensed contract G3s/HK91s, like the original SARs and FMPs. It is built on licensed H&K tooling, up to specifications with proper materials...Unlike all other "clones" in remotely the same price range...
