I had a HK91, PTR 91, and a PTR 91K in the past when they were using the parts they bought from the Portugese gov't auction. Not bad rifles, but I never could totally get into the platform due to the lack of mounting an optic, etc. The FAL has a lot of the same short comings to it as the 91 so I stayed with what I already knew. Now that the AR is better suited for certain tasks and there is more support it feels right to me, or at least the Colt 901 does.

No arguing that the 91 can be said that it is robust, there are some countries in harsh environments that adopted the G3 for that reason. But lets look at it this way, the Germans wanted the FAL and the rights to manufacture it in Germany; but the Belgians said no--wonder why after two wars in the first half of the century. The German BGS used the FAL while the military went to Spain and got the rights to the CETME, and with a little work came up with the G3. HK was a product of the Belgians denying the Germans the ability to make the FAL in their own country.
