These roller-locked HK-style "clones" ARE NOT made by HK GmbH in German. Those are the only HK-style weapons that meet the original designer/manufacturer specifications.
HK GmbH has ZERO CONTROL over how the "licensee" makers from Pakistan, Greece, Iran, etc make their products and the materials and quality is all over the map. That license agreement is between Germany and the host country NOT WITH HK. A quick look at all the problems with "clones" posted on HK Pro will give you some idea of the quality of these copies. It is rare to see posts on other than operator or ammo issues with genuine Oberndorf-built HK's.
That being said there are those who have reliable clones and swear by them but that is the exception versus the rule in my experience. I witnessed many issues with clone parts failures (bolt heads, firing pins, barrels, even locking pieces) that I never saw in a "real" HK weapon.
HK's failure to offer a German-made roller-locked rifles in the US opened the door to these clone makers filling that void. Can't blame them. No one can argue the vast difference in purchase price for the HK90-series that are no longer made - supply and demand and the supply was shut off years ago.
The clones sellers will tell you they are made on HK tooling or to HK specs or are "as good as" but it is simply not true. HK GmbH stands alone as THE quality manufacturer of these roller-locked guns and anything else is a compromise in quality and performance. Having tools and parts does not make a genuine HK product.
